PsiWin 2.3.3 under Windows 7 Ultimate

Windows 7 Ultimate running PsiWin 2.3.3

Let’s hear it for Psion. Not only did they make first class PDAs, which still have a massive community of user going nuts over, but their PC connectivity software PsiWin — which they stopped developing at version 2.3.3 (copyright 1997-2001) — still works perfectly even under the beta version of Windows 7 Ultimate edition.

  1. Hi, we use Psion Workabouts extensively and employ Psiwin and Epoc to communicate with the Psions. Along comes Windows 64 bit systems and we are unable to get Psiwin to work. Is there any information or advice you can offer to overcome this problem please?
    best regards, Mike

  2. Please tell me how you managed this wonder. I have Windows 7 ultimate installed and tried to connect my computer with my PSION 3mx but got only negative results.
    Please answer
    Many thanks

  3. Hi Goesta
    Sorry delay replying – got married!!
    No problem with 32 bit but you have to choose your adapter carefully, can supply adapter if you want.

  4. I’m going to blog about this in more detail soon, but I managed to get my Psion 5mx to connect to my work PC, running Windows 7 Professional 64-bit using Windows 7 “XP mode”. Worked a treat. The only real gotcha was to make sure that the Virtual PC (XP Mode) COM port setting matched that on the actual PC (Windows 7).

  5. I am still stuck trying to get PsiWin to run under W7 (64 bit Home Prem). I have got the Psion (Revo) to connect OK and I have the short cut to Psion Backup set to run under XP SP 2 (or 3) but when I click the short-cut all I get is the pop up asking if I want it to make changes to the computer and nothing else seems to happen. I have checked the port setting and they are the same as on the Psion. The system tray shows the Psion is connected. Any ideas as to what to do next. I have noted Gareth’s point about checking that both the computer and XP mode port settings are the same but I don’t know how to do this (not very techie! expect the computer to run like a washing machine – turn on use it). Any ideas would be appreciated. I am sure it can be done.

  6. I can connect my PSION Revo Plus usong windows 7 32 bit but PSI Win 2.3.3 doesn’t recognise the device. When the device is in range, windows makes a noise and it says “EPOC device in range”. I have the option to “send to: My PSION D:/” and “My PSION E:/” but when I try to send, it opend up PSI Win which ALWAYS says cannot connect – no matter which com port I use. I’ve matched the speed settings with the modem and the PDA. The only other thing is that I can select to change the chipset on the IRDA driver drop-down menu from “MOSCHIP/SIGMATEL/etc/etc” there are about 10 to choose from. What should I do to get it to work with PSI win (whihc I installed in XP mode)? I’ve also tried IRmon2000k (I think that’s what it’s called) but that didn’t work either.

  7. Just spotted the screen-shot of your Windows 7 installation – how come the active-window border is blue with a drop-shadow and not transparent like the inactive-window behind it which shows the blurred-out desktop??

  8. To use psiwin suite 2.3.3 with windows 7 (64 bits), you just have to select compatibility mode for psiwin programs (.exe) in program folder (C:\Program Files (x86)\Psion\PsiWin) with WINDOWS XP service pack 2, and it seems to work fine. Hope this will help.

  9. well I just tried to install PsiWin 2.3.3 on Windows 7 (64-bit version) and InstallShield popped up a dialog box saying ORG21.exe is a 16-bit program and not compatible. In clicked on ‘cancel installation’, which did not reverse the steps already performed, but only stopped the installation. Now I’ve got a PsiWin Start-menu entry, files under \program files(x86)\PsiWin and I am unable to uninstall it. bah.

  10. Hi – I found my old Psion Revo when clearing out old PDA’s (quite a few!). Will this connect to Win 7 32 bit or does it need to be Win 7 Ultimate 64?

  11. I have been using my Psion mx and Psiwin 2.3.3 as my address book for years but think it must be time to move on. Can anyone suggest an alternative that is not Outlook, that is as close to the Psion address book as possible. It is the simplicity and free structure that I like and that I can search using any string. My address book is based on companies not individuals so I have many names and phone number under one entry for a company. I thought that there might be a program I can run on a book reader or tablet. Does Lotus notes addressbook work in a similar way to the psion.

  12. Psiwin has run happily on WinXP but with Windows 7 Professional 64 bit, when I try to install psiwin233_english.exe, I get an error message ‘the program …… PsiWin\ORG21.exe cannot start or run due to incompatibility with 64-bit versions of Windows’. I tried the program compatibility troubleshooter but got same message. Any suggestions ?

  13. Very frustrated, would appreciate help trying to get Win 7 64 bit to see my psion 5mx. I followed you blogs, installed Startech ICUXUSB232 serial to USB connector with chipset Prolific PL 2303 ID, connector 1-DB9 Male and the computer sees the connector. I installed psiwin 2.3.3 and no luck seeing the psion. I uninstalled the psiwin, reinstalled it after cleaning the register, checked that the com ports (3) matched and emptied the temporary folders and even switched off the FIFO buffer on the serial port but still no luck, running in Win XP (x86) service pack 2 emulation mode, but still no luck. Would appreciate any advice. Muchas gracias. Ted

  14. Garth- one more thought- on another chat site he suggested deleting one file: Program Files\Psion\Psiwin\ORG21.EXE which he said was for an old version and helped him connect his Psion. I deleted the file, rebooted and still the computer couldn’t see my 5mx. When you respond with help, should I first uninstall, regclean and reinstall to get that file back or does it not matter? Thanks again Ted

  15. Hi, Having done all required items for my psion netbook to be connected to PC (OS Win7 Pro), I haven’t achived it yet. Am i doing something wrong?
    1. I bought a USB-to- Serial adaptor
    2. I connected that to PC and psion and win 7 downloaded and installed the suitable driver
    3. I set the same COM port in psiwin and pc
    4. I tried to connect

    No way for that at all after uncounted efforts. Please help. psion without connection is useless.

  16. Hello Gareth,

    I have Windows 7 Professional like you do. I tried both options for downloading PsiWin 2.3.3, but each time it appears that I get only PsiWin 2.3. Do you have an idea of what I’m doing wrong? Thank you.

  17. Hi Gareth.
    I’m hoping you can shed some light on a technical problem which, like a number of other Psion users, I’ve encountered with the PsiWin (V2.3.3) application. I’ve installed it under the 64bit version of XP Professional. It successfully installs the ‘Psion Backup’ & ‘Psion Synchronizer’ icons on the desktop, (which are simply just shortcuts to their respective applications), and they work just fine. E.g. if I launch the Backup application, a successful connection is established with my Psion Revo Plus, and I can successfully perform a backup operation. Same thing applies to the Synchronizer application. The problem I’ve encountered though, is that the PsiWin installation process fails to install the “My Psion” icon on the desktop, which as you would know, unlike the two icons I’ve already mentioned, is a special icon because when it’s clicked, it opens up a window showing the contents of the PDA itself. That of course allows the user to transfer files to and from the PDA. And there lies my problem. I can back up. I can synchronize. But I have no means of viewing the contents of my Revo, or transferring files. The “My Psion” desktop icon also offers a variety of options in its right-click context menu.
    Any help would be tremendously appreciated. Thanks Gareth.

  18. I have precisely the same problem as Matthew – my Netbook connects to Windows 7 for archiving etc., but there is no “My Psion” on the desktop, or in Windows Explorer. I’ve been using Psiwin since the bygone days of the Series 3 and Windows 3.1, but I have not encountered this problem before!

    Kind regards,


  19. I use a card reader (store all my files on a compact flash card) and then use psi win to convert files, Do not use sync with outlook!

  20. Just for the case that it may help someone: Moxa NPort 5110 serial device server saved me.

    I tried two different USB-to-serial converters, both with the same result, everything looked OK, I was even able to check that the serial connection is working using Hyperterminal/PC and Comms/Psion 5mx (had to copy the missing hyperterminal from XP), but PsiWin never succeeded to connect. What helped in my case was a Moxa NPort 5110 1-port RS-232 serial device server, which I happened to own. This is a small box that connects to a ethernet LAN on one side and to a serial line on the other side. Installed a Windows 7 version of the NPort Administration suite, mapped COM1 port to the device, connected Psion to the serial port on the NPort, and it worked.

  21. Just a sad update:
    NPort Asministration Suite makes Windows 7 booting about 30 seconds longer (stalls just before the animated colored Windows logo appears).

  22. I have been running PsiWin on Windows 7 – 64-bit for over a year with NO problems, except that the “My Psion” icon does not appear on the desktop, and therefore I can’t transfer files between my RevoPlus and the PC. The likely explanation for this is that “My Psion” uses 32-bit code that for some reason will NOT transfer to any 64-bit PC. The other PsiWin programs, including backup, restore, copy anywhere, etc. work just fine.

  23. I have it working on Win 7 64 bit ultimate except for My Psion – when I run it, it brings up Psion Backup instead. I got the error with org21 when I installed – is this connected with My Psion not working? I can do successful backups – without setting compataiblity mode.

  24. I was able to get the My Psion Icon back on the desktop by copying the contents of

    @=”My Psion”

    from the Wow6432Node location, but the “Open” option is missing – which is why it does a backup when pressing “My Psion”. Any ideas how to get the “Open” option back?

  25. Yet another update – I now have the Open option, but it doesn’t do anything, and when I click on “Properties” it says that the option is not available. Seems that the secret is copying everything from the Wow6432Node location, if it’s related to Psion – just not sure that I have caught everything.

  26. After two weeks trying to connect my Mc218 (psion 5mx clone) to my windows 7 32 bit ultimate note book I’ve realized these simple fact:
    1) not all usb to serial cables works with psiwin under windows 7 32 bit.
    The gmus-03 based on the PROLIFIC 2303-H chip I’ve installed with the proper driver works fine with the comms application in terminal emulation transferring files with the Y-MODEM protocol between the MC218 and the notebook and viceversa, but don’t works with PsiWin 2.3.3.
    2) The same cable works fine with Psiwin 2.3.3 under windows XP mode virtualization.
    3) using a express card can solve Your communication problem. I have bought a “Hamlet XRS232EXC – EXPRESS CARD Serial RS232 Hardware” that works fine with windows 7 32 bit and PsiWin 2.3.3.
    I hope this can be useful.

  27. Just adding a little bit of info on my experience of getting psiwin2.3.3 onto Windows7 Pro (64-bit) (just got a new machine, with upgrade from XP to Win7 Pro 64-bit). I read lots of postings, here and other places, about pswin322 onto Windows7 (64-bit). So, feeling forewarned is forearmed, I gave it a go (coincidentally, I’ve got a PCI Express 2-port serial card on the machine, specifically for the Psion cradle, so no need to use a USB-to-serial converter). Oh, and it’s a Psion Revo.

    PSIWIN Installation
    • Got the installation done (psiwin 2.3.3)
    • Got the error about file ORG1 (or whatever) that I expected (that others had seen), and an error about tryng to install 16-bit software and ignored them without too many apparent problems
    • Two icons appeared (Backup & Sync), but not ‘My Psion’ (as expected); no big deal. Start menu items are all there (under entry Pswin 2.3)
    • Once I’d told Psiwin which COM port to go for, it connected fine (I had to wait for it to fail to connect to get the Settings menu: with no ‘My Psion’ icon this was the only way I could find to get into Settings).
    • It seemed to do a full backup without a hitch, took about 6 mins, and I got “Backup completed” box.
    • My Psion in the Start/Psiwin menu (there’s no desktop icon) goes straight to backup

    So, it’s on, it does a backup (which is a very important consideration). Obviously not full functionality (e.g. no My Psion) but it does a backup, I didn’t have to hack the Compatibility setting, I didn’t have to install or run it in the WinXPVM (I suppose you could do that if you wanted full functionality of Psiwin). If I want a file that’s on the Psion, I can pull it out of the backup area in Windows (C:\EPOC), and the Converter (in the Start/Psiwin) does its job. I haven’t tried sync’ing yet, but that’s not something I use often.

    I suppose it’s a bit of a bodge, but it does what I need and pretty much out of the box.

    So, thanks for the info from everyone on this thread and elsewhere, and I hope my experiences might help others.
