Hi. We're assuming for the moment that RS 2008 developers (on OS WS2008R2) and rs 2008 std (on OS WS2003) use the .net framework for doing things like saving reports to PDF. We see a few versions of the .net framework on a development 2008 developers server where our new report saves our report uncorrupted to PDF. We see a few on the 2008 std production server to which we migrated where we are experiencing corrupted pdfs. Is there somewhere I can look to be sure on each server which (if any) version of the framework is enlisted by RS? this is the version of the sql engine on the server where we are having the problem SQL Server 2008 (SP3) - 10.0.5500.0 (Intel X86) Sep 22 2011 00:28:06 Copyright (c) 1988-2008 Microsoft Corporation Standard Edition on Windows NT 5.2 <X86> (Build 3790: Service Pack 2) (VM)
