Setwow setting in IBM Cognos Controller makes the system run in 32 bit mode which causes problems

Troubleshooting


Problem

When reusing an existing server (that has been running earlier versions of Controller) it is possible that the server has been configured to force all .NET assemblies to run in 32 bit mode (using the “ldr64 setwow” command). This in turn causes problems for especially the FAPNTService.exe and the CCRBatch.exe service that as of 10.2 will need to run in 64 bit mode in order to function properly.

Symptom

In the case of the FAPNTService running in 32 bit mode the most common error is that the service will not be able to log on to TM1. This can be seen as a log message in the FAP log.

The easiest way to check if the services are running in 32 bit mode (which they should not be) is to start the Windows Task Manager and then locate the services in the list (you may have to tick the “show processes from all users” checkbox to see all services. If there is a “*32” text after the name of the service this means that the service is running in 32 bit mode.
