Dynamics NAV RTC hangs when previewing/printing reports

Problem:
When previewing a report you only getting a small window in upper left corner with only a text string with the name for the report and the rest blank. When I trying to close this window, you get an error message: “Errors exist. Do you want to discard changes?” (Y/N). Pressing Yes, hangs and close the RTC client.

Probably cause:
You have installed the RTC client outside the setup chainer or you have uninstalled Report Viewer 2008. It may also be that Report Viewer 2008 installation is broken.

Solution:
Run DVDPrerequisite ComponentsMicrosoft Report Viewer 2008 ReportViewer2008.exe and select install or repair depending on if Report Viewer 2008 was already installed.
