Need some help with Cognos 8 error (Analysis Studio)

[kmfloyd]

Our primary admin is on vacation and I've been forwarded user issues.  In short, users are creating reports in Analysis Studio and saving to my folders.  When they go back to view them later, they are getting the following error:

ANS-MES-0005 An unexpected error occurred.  If the problem continues, undo your action or close and re-open your Web browser window.  Does anyone know the root cause?

Problem(Abstract)
On some Windows machines, when attempting to open Analysis Studio, an error message is received when trying to either create a Blank Analysis or open the Default Analysis. The solution in this document is applicable in situations where only specific users and/or specific machines experience this issue. If all users who attempt to use Analysis Studio experience this error, the root cause may be something different and it would be best to refer to other KB documents for the "ANS-MES-0005" error. 
 
Symptom
ANS-MES-0005: An unexpected error occurred. If the problem continues, undo your action or close and re-open your Web browser window. 
 



Cause
A Windows Registry entry is pointing to the incorrect version of MSXML.DLL. "MSXML3.DLL" should be being used, not "MSXML.DLL". 
 

Environment
Cognos 8 
 

Resolving the problem
NOTE: The following solution requires a registry modification. Incorrectly modifying your registry can render your applications and/or OS inoperable. Only follow these steps if you are certain of what you are doing. If you are unsure, ask your network administrator for assistance.
The "(Default)" registry key in the "[HKEY_CLASSES_ROOT]/CLSID/{2933BF90-7B36-11d2-B20E-00C04F983E60}/InProcServer32" registry folder needs to be corrected. The key should contain this pathname:
"%SystemRoot%\system32\msxml3.dll"

If the DLL referenced in the pathname is different than "MSXML3.DLL", correct it so that it is "MSXML3.DLL".

Steps:1. Locate the following registry folder in REGEDIT:
[HKEY_CLASSES_ROOT]/CLSID/{2933BF90-7B36-11d2-B20E-00C04F983E60}/InProcServer32
2. Open the key called "(Default)" for modification. The value of the key should be "%SystemRoot%\system32\msxml3.dll" If it says "%SystemRoot%\system32\msxml.dll" make sure to correct it.

Changes take effect immediately, so Analysis Studio can be tested immediately

We were also getting error:
ANS-MES-0005: An unexpected error occurred. If the problem continues, undo your action or close and re-open your Web browser window.

We are using Cognos 10.2.2, users would get this error when ever they tried to launch an analysis report based on a 32 package and the request got routed to a 64 bit report dispatcher.  We were getting the error with: IE, Chrome and Firefox 

Transformer cubes use a 32 bit technology.  To resolve, I created a routing rule for all packages NOT published with dynamic query mode (this includes Transformer cubes) and added on 32 bit report dispatcher to our Cognos cluster.
