Has anyone come across this issue?
Seems MS have broken it with their own update:
A number of people have reported problems using the Active
Our Server environment : SQL2008 x64 SP2 Reporting Services on Windows Server 2008 x64,
Client PC environment: Windows XP SP2 with IE6 or higher, all users are login to Active Directory, users are not members of local Administrator or power user group.
Error: When a user printing a report getting an error as "Unable to load client print control"
Solution that work for us: replace following files in sql 2008 with SQL 2008 R2
Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer\bin RSClientPrint-x86.cab RSClientPrint-x64.cab RSClientPrint-ia64.cab
Once you replace the files one server users wont get above error and they do not required local power user or admin right to download Active X. Recommending to add report server URL as a trusted site (add to Trusted sites) via Active Directory GP.
