Hi.


I want to uninstall some another application with uninsaller of my application.

For that I created batch file which uninsall both applications which contains

MsiExec.exe /X {0C20DEB6-642F-30D9-BBB8-D27A747E8132}

MsiExec.exe /X {CF79A9E2-D043-46F7-B833-7360AB8F7D7E}

Now I want to call that file from AddRemove programs Remove button of my application.
For I changed HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\myapp

uninstall string with path of batch file and tried to uninstall application from add/remove programs but still it uninstall only my application not another.

Then I tried to change the uninstall string of my application with another application uninstall string. Then tried to uninstall application from add/remove programs but still it uninstall only my application not another.
