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.
NOTES:
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
