Prob Printing Crystal Rpts with Runtime

We distribute reports to users to print with the Crystal Reports runtime engine. Repts developed with Crystal Reports 7.0 32 bit report designer. Printed from Centura SQLBase 7.0 Database. Reports print okay with systems running Win 98. Systems running Win95 get error ‘CRRUN32 caused an invalid page fault in module SQLNGCI.DLL at 0137:019c14d’
or ‘CRRUN32 caused an invalid page fault in module KERNEL32.DLL’
Sometimes, after clicking the close button, the report then prints. Other times, it aborts the program or locks up the system.

Anyone have any ideas what the problem might be?
