ReportViewer Client Print Control "Unable to load client print control"?

Question

Has anyone come across this issue?

Seems MS have broken it with their own update:

A number of people have reported problems using the ActiveX print control in the report viewer after installing Microsoft Update 956391. Specifically, users receive the error "Unable to load client print control" when clicking on the print icon in the report viewer toolbar. I would like to explain what is happening, why we did it, and how to fix the problems that you or your customers are experiencing.

From here: http://blogs.msdn.com/brianhartman/archive/2008/11/05/client-print-fails-to-load-after-microsoft-update-956391.aspx

I can get it to work in ReportManager again but in our app (RSinteract) which references version 8.0.0.0 of the ReportViewer it is not working no matter what I do.

I've tried everything here: http://www.technologystudio.net/blog/post/Microsoft-Update-KB956391-breaks-Reporting-Services-ReportViewer.aspx

I'd like a fix that doesn't require me to rebuild and redeploy to all my clients. Any ideas?

Answer 1

Found a Fix:

1. First ensure that printing is working from Report Manager (open a report in Report Manager and print from there).

2. If it works go to Step 3, if you received the same error you need to install the following patches on the Report Server.
