Cannot Uninstall CA XCOM Data Transport 11.6 SP01 after initial install.  Because when I try the install again, I get the message

CA XCOM Data Transport r11.6 SP01 (64-Bit) is already installed on your system. The existing version needs to be uninstalled first before the installation can start. The installation will exit now. 

Cause:

When you initially installed, you might have missed the last steps which are displayed on console 
XCOM_HOME=/opt/CA/XCOM
export XCOM_HOME 
and executed xcomqm -r too soon and the original installation was probably successful. 

And then you uninstalled
In your case, a registry file was probably left behind: 
This file is /var/.com.zerog.registry.xml 
preventing you from doing a new install

Resolution:

/var/.com.zerog.registry.xml has information related to XCOM, patches, version etc. 

If it did not get deleted, then you will get the message 
CA XCOM Data Transport r11.6 SP01 (64-Bit) is already installed on your system. The existing version needs to be uninstalled first before the installation can start. The installation will exit now. 

The resolution is to delete this file 
rm .com.zerog.registry.xml
