Unable to load the client print control after installing KB956391

Recently, one of my colleagues put together a very comprehensive action plan that normally should fix this issue.

So, if you happen to have this error message while trying to print a report in Reporting Services 2005 after having recently installed the latest security patches, here is how it can be solved.

Since the main cause is that this patch updates the ActiveX controls, we will have to follow the below steps.

1. For SQL Server 2005 Reporting Services we should have at least version 9.0.3282. KB article: https://support.microsoft.com/kb/954607.

Download location: https://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=5148b887-f323-4adb-9721-61e1c0cfd213

2. Install separately the latest version for the ReportViewer control. Since until now we have two major versions of the control - version 8 and version 9, we should check that both are up to date.

a. for version 8 we have : https://www.microsoft.com/downloads/details.aspx?familyid=82833F27-081D-4B72-83EF-2836360A904D&displaylang=en - Microsoft Report Viewer Redistributable 2005 Service Pack 1

b. for version 9 we have: https://www.microsoft.com/downloads/details.aspx?FamilyID=bb196d5d-76c2-4a0e-9458-267d22b6aac6&DisplayLang=en - Microsoft Report Viewer Redistributable 2008 Service Pack 1

After the reportviewer control is updated, an IISreset should be issued in order for the changes to take effect.

 3. On the client computers, have the update https://support.microsoft.com/?id=956391 installed.
