I have a client who just installed a VFP6 -based application on his Windows 2000 (SP 4) system. Now when he tries to run Photoshop Elements 2.0, he gets the following error:

*Entry point not found*
The procedure entry point RtlUnhandledExceptionFilter could not be
located in the dynamic link library ntdll.dll

When he reformats the hard disk and re-installs Windows 2000 with all service packs, then reinstalls Adobe, adobe works fine. As soon as he installs my VFP app, Adobe stops working again with the above message.

Clearly some dll dependency gets hosed here. Has anyone else seen this error? My app uses the following OCX/ActiveX/DLL components:
