Hi Team,

We are not able to uninstall the custom action from the user machine, Please check the below steps for more information.

1. We are trying to achieve silent uninstall with following command

psexec.exe -s -i cmd /c msiexec.exe /x {1ABC3A9F-11A7-498F-B8EA-F55CF391271B} /qb

Error Message: cmd exited on MKAW7X64VANILLA with error code 1603.

2. From the logs I can see below exception message,
