Which version of QCW did you install? Which version of Windows is being used on this station?

There are 2 issues that may cause this error.

1. The correct report table is not being used. If the station is not pointed to the correct Report tables drive or the report table was not installed, you may get this error.

2. There is a UFLDTDIF.dll (and/or U2ldtdif.dll) in the Windows\Crystal directory. This file is installed by A4W & it is not compatible with QCW. UFLDTDIF.dll adds this addtional function to Crystal: DateTimeDiff.
