Environment
Microsoft Windows 64 bit
Situation
Customer is unable to install AC 2.7 SP1, receives "AC is not installed" error.
Resolution
This issue happens when only the console is installed on a 64-bit environment. Service Pack 1 reads the following registry key from the 64-bit hive:
HKLM\SOFTWARE\NetIQ\AnalysisCenter\2.0
But when the console is installed on a 64-bit machine, this registry key will be under the Wow6432Node hive.
To overcome this problem, we have to manually create a registry key in the native 64-bit hive:
HKLM\SOFTWARE\NetIQ\AnalysisCenter\2.0
Once this key is created, add a string value "InstallPath" which should be same as it is in the Wow6432Node registry hive.
Once these steps are completed, you should be able to install SP1 for Analysis Center 2.7.
