Troubleshooting
Problem
User launches Controller from website (for example http://servername/cognos8/controllerbin/ccr.exe). User receives error message However, if the administrator tries launching Controller directly from Windows Explorer (for example by launching ...c8\webcontent\ccr\CCR.EXE on the application server itself) then Controller launches OK.
Symptom
Screen error message (inside a web page):
- http://servername/cognos8/controllerbin/ccr.exe - Microsoft Internet Explorer
