A client has upgraded to Windows 7 Pro. They are using OI v 4.1.

When they try to run a couple of programs they get a message "Unrecoverable Openengine - Out of Memory". This happens on all Windows 7 machines on their network. It does not occur on XP Pro machines. I have checked all the obvious issues - access rights, DEP etc and everything seems ok. Can anyone tell me where to look next?

OI v4.1x and Windows 7 is not a supported configuration. Upgrading may be the best option.

You may have to disable UAC which probably won't make the IT people happy due to security risks.

OI v4.1x is supported under Win98SE so it may not run at all on Win7 64bit. You can try running OI and the engine in compatibility mode. My experience with compatibility mode hasn't been good. Sometimes you can get stuff to run but Win7 doesn't seem to hold the settings and you have to set the mode every time you run the program - even when logged in as an administrator. The older the programs are the less successful compatibility mode. OIv4.1x is 10-11+ year old.

You may have to register any of the OCX files and some of the DLLs used for printing and Reporter.

If running Win7 Pro or Ultimate Virtual XP mode maybe the way to go but it can become an administrative nightmare.

Warren,

I think UAC was the culprit. The app (or at least, from same source) runs on my notebook. After investigating, I find I must have turned UAC off ages ago to do a proof-of-concept upgrade to v8.x/9.x.

Dare say this experience will provide an appropriate reminder to legacy users to upgrade.

You might have to run it in XP mode, which is essentially a seamless virtual machine.

See http://www.microsoft.com/windows/virtual-pc/download.aspx, which was correct at the time of this post.
