Release : 11.6
Component : CA XCOM Data Transport for Windows
There is a cleanup utility designed to resolve all problems with incomplete uninstalls for various XCOM versions which prevents a new install from executing.
The utility can be accessed here: ftp://ftp.broadcom.com/pub/xcom/xcpcnt/Uninstall%20program/
Note: Per the readme.txt file:
To cleanup 32-Bit versions of XCOM, use cleanup32.zip and file xcomunin32.exe.
To cleanup 64-Bit versions of XCOM, use cleanup64.zip and file xcomuni64.exe.
For Windows Server 2008 SP02, use xcomunin64.exe utility irrespective of XCOM version.
After the relevant xcomunin*.exe file has completed and the server has been restarted the XCOM install should then proceed without any problems.
If the install is still blocked after running the cleanup utility then running the following commands to delete 2 more registry keys may be needed to resolve the problem (has been reported when the previous install was r11 32-bit):
REG DELETE "HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\XCOM\RemoteSystemsTS\" /f
REG DELETE "HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\XCOM\" /f
