  • Can you upgrade a 16-bit app written in Omnis to 64-bit

    Posted by Steve Bonnici on July 5, 2024 at 2:52 pm

    This is a real long shot and a stab in the dark

    About 20 years ago I inherited from a developer an application sold into the car industry. I believe it was developed in Omnis Studio 7 as a 16 bit application. I have continued to assist users who still use it although I have not sold it in maybe 8 years.

    it works okay on Windows 7 through to Windows 10 as long as it is 32-bit Windows.

    The issue now is that Windows 11 does not have a 32-bit version only 64-bit

    So I am just wondering if it would be possible to get it upgraded to a more up to date version to run on Windows 11 64 bit?

    Please dont laugh lol

    Hi Steve

    I am an Omnis developer still using Omnis 7. I do my Dev on a Win 10 PC but I have just successfully installed Omnis 7 version 7.3.8 on my newer Win 11 PC. After a cursory test it seems to be working fine. I am also helping a user organisation upgrade their platform to Win 11 and Win Server 2022 and SQL Server 2022. All is working fine.

    Or have I misunderstood the question?

    Cheers. Neil

    Hi Neil,

    It may be more of I do not know what I am asking.

    The original program was developed on a Mac and re-developed for Windows by a chap who has long disappeared. I must have been re-developed around 1995. I recall that we used to buy licences from Raining Data and that they began with C7RSI.

    It will not run on 64-bit is a 16-bit application but runs okay on 32-bit.

    I can send you the exe file if you like as it is not that big or send you a link to download it

    Hi Steve

    I think it is me not understanding what you are trying to do.

    Omnis 7 installs as a 32 bit App in the Program Files (x86) folder. Unless you have a version of Win 11 that does not have the 32 bit folder.

    I am running:-
    Edition Windows 11 Home
    Version 23H2
    Installed on ‎08/‎09/‎2023
    OS build 22631.3737
    Experience Windows Feature Experience Pack 1000.22700.1009.0

    Are you trying to install on a Windows server which may not support 32 bit Apps? Sorry, not my area of expertise.

    Perhaps someone else can give you better guidance. But I will help within my limited experience.

    Hi Neil

    The application was written around 1995 so it may not be written in Omnis 7.

    I do not know how to find out

    I have managed to set it up as a working application in Hyper V

    That might be a way forward for me

    Hi Steve

    We were using Omnis 7 by 1995. The fact the your licenses start C7RSI proves that it is written in Omnis 7. The Omnis library will be a .LBR file.

    If you can work with a Hyper V platform that will be good. Are you making any system amendments i.e. using Omnis 7 Development version? License number starts C7DSI, so you can open the library and edit the formats. Or just helping the user client to upgrade their platform.

    Hope you are now in a successful place!

    Cheers. Neil

    Thanks Neil,

    Do you know if someone could take the program and upgrade it a newer version retaining its functionality.

    There would be an opportunity to develop the program and get more sales if it ran on say 64-bit

    Yes, it’s possible to go from Omnis 7 to Omnis Studio 11, just not in one step.

    We originally started with Omnis 7 and converted some of these to Omnis Studio. It all depends on how the Omnis 7 app was built. It’s partly automatic conversion, and partly manual conversion.

    Check out this article on Omnis’ website:

    If you want to contact me privately I’m happy to talk further with you about this.
