Any ideas what may cause the message like this. The problem seems to be very rare. Originally it was a permanent problem for the particular client, after recreating profile ( customer's OS is Windows 2000 ) and reinstalling the application it became intermittent. For instance, when other VFP8 exe which does some updatiing is launched from Wise Installer it may ( or may not ) pop up, but the application runs fine. Also since for installing the application pretty old Wise Installer is used all Foxpro run-time DLLs are placed into Windows system directory

TIA
