Just wanted to share the following:

After installing FileMaker Pro 5.0 on a machine I would get this error:

"FileMaker Pro could not be launched because of incorrect installation, missing system components, or insufficient memory. Please see the FileMaker Pro Documentation"

The computer is a Dell just out of the box, and the FileMaker copy was working fine before on an older computer...

On the FileMaker site, it referred me to Microsoft Article ID Q293322. It refers to some "issue" with Microsoft Windows NT 4.0 with Service Pack 6a with certain hotfixes... Now on the Microsoft site, there is no solution, just an invitation to call them (with "normal" support costs...).

Uninstalling Win NT service packs or hot fixes did not help. I finally decided to uninstall Internet Explorer 5.5 (with any hot fixes) and re-install FileMaker: it worked! I re-installed Internet Explorer 5.5, and FileMaker 5.0 still worked. Bingo!

I am glad we could resolve the problem but was disappointed that FM and Microsoft did not make it very clear...

There is also issue on some Dell, W2k and FM5 -- it was fixed in FM5.5.

Problem is with type of used sound chip...

The PC I have does not use Win 2000 but Win NT 4.0 with service pack 6a. So the message found at FM was not incorrect. It appears, from the solution I found, that the problem had more to do with the browser installed than the OS (one could argue that it's not that different...)

I know it is not recommended to use IE5.5 on win machine with FM server. Only up to IE5.

I do not know, if we should blame Microsoft or FileMaker Inc.
