Unable to load client print control
December 5, 2008 Leave a Comment
UPDATE: Further information on alternative fixes has come to my attention via StackOverflow.
This new error has popped up since Microsoft released the update KB956391.

The update is for a vulnerability in the GDI+ DLL which allowed a malicious user to execute code on the client machine (good old! – ed). The fix uses ActiveX Killbits which is a setting that Internet Explorer checks for each ActiveX control. If the Killbits are set, IE refuses to load the control.
The update set the Killbits for the version of the RS Client Print ActiveX control which is used by the version 8.0.0.0 of the ReportViewer which is referenced by RSinteract (and Report Manager). Thus the printing will not work in either.
To fix Report Manager you need to apply the ReportViewer SP1 patch and the Security Update for SQL Server SP2 (KB954606). Once this is working again you can fix RSinteract.
To fix RSinteract you need to apply another Security Update for SQL Server SP2 (KB954607).
Let us know if this fix doesn’t work for you.
