We have CA-WAAE release 11.3.6 and WCC 11.3.6 installed both on the same Windows 2008 R2 server.

We would like to uninstall both products in order to install properly from scratch the latest release.


The WCC 11.3.6 release uninstall procedure is completed successfully and we also rebooted the server.

But when we try to uninstall the WA AE release 11.3.6, the uninstall procedure fails with error message :

AutoSys SDK being used by WCC. SDK will not be uninstalled.


Consequently, CA-WAAE is not uninstalled and remains referenced in the Windows Programs and Features list.

We double checked, there is no WCC components and it is completely uninstalled.

WAAE 11.3.6 Release on Windows

WCC 11.3.6 Release on Windows
The encountered problem is related to a registry key which will need to be removed manually.

The solution is to delete the "WCC_lock" registry key under:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ComputerAssociates\Unicenter AutoSys JM\11.3_Base\CurrentVersion\SDKInstalled

Problem resolved by applying the solution. WA AE and SDK are uninstalled and reinstalled successfully.
