ISSUE: Receiving "Access violation at address 0046A807 in module 'GPReports.exe'. Read of address 00000000." when trying to print report using GP Reports Viewer. Issue reported on only some (not all) reports and on some (not all) computers.
SOLUTION: This was caused by Arabic characters in the names of some Crystal Reports. Changing the report names to English and confirming the path to them was showing up correctly in GP Reports Viewer setup fixed the problem.
