uninstalling a msi during/after uninstalling main application

I have an application A and also a support pack B. You install package B with as a feature prerequisite during the installation of A. Now I would like B to be uninstalled if you uninstall A.

What I did was in A was to create a custom action as this:
Type = Launch another .msi package
Location = Launch another .msi package
Source = {product code of B}
Target = ALLUSERS=[ALLUSERS] REMOVE=ALL

Install Exec Sequence = After InstallInitialize
Install Exec Condition = Installed AND REMOVE="ALL"

Now I install A (and B is installed by IS automatically). When I later go to Add/Remove programs and uninstall A, A is removed from add/remove program list but B is still visible.

It seems that A is trying to uninstall B but somehow only does part of the job. No the only way to remove B is to go to the registry and hunt down all places in order to not have it visible in the add/remove programs. So i tried LaunchAppAndWait in install script. This is giving error as Another setup is already running.

Please help how can i uninstall pack B.

Thanks in advance

Re: uninstalling a msi during/after uninstalling main application

You cannot run two instances of msiexec exe at a time.
Hence, when you are running your main application, you cannot use msiexec again and try uninstalling application B.

Try if moving your CA, outside InstallInitialize and InstallFinalize does help.

Perhaps read on chained msi packages. Not sure but there might be a solution there.
