Further Information on Report Viewer Client Print Control bug
April 22, 2009 Leave a Comment
A while back I wrote a post about the “Unable to load client print control” error that Report Manager (and RSinteract) was throwing after Microsoft’s auto update KB956391.
I also asked a question over at StackOverflow which I ended up answering myself. Yesterday follow up information was added, which may be of use if you have trouble with the fix.

I have had the same problem (on several different servers). Applying SP3 and Report Viewer SP1 has helped on some of the servers, allowing the client machines to connect and download the control with no problem. However, I have had one server that, even after applying the updates, when accessing the report viewer using a client machine, it was still giving me the error. On looking into the exact URL GET request that is being sent, I discovered that it is possible to force the client machine to connect directly to the Report Server to download the control.
The user would need to enter the following url:
This should then pop up the required download/install prompt.

Hi,
I got this working with out removing any patches. The above patch was not working too. Finally what I did was on the IIS server install the following patch and reset / restart the IIS server. This is not for report manager application. This is for any ASP.NET Web application developed in .net3.5 using VS2008 http://www.microsoft.com/downloads/details.aspx?familyid=6AE0AA19-3E6C-474C-9D57-05B2347456B1&displaylang=en
I hope this helps anyone else with this problem.
