>
> *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.
