Uninstall via custom action blocked by original uninstall

"Error Message" wrote:
Another program is being installed. Please wait until that installation is complete, and then try installing this software again.

I've tried a few different settings. Deferred, immediate, commit, etc.

I've tried different locations in the exec sequence.

I've tried different locations in the ui sequence.

I've tried asynchronous, synchronous, etc.

This strategy has worked uninstalling other programs, but not this one.

Any advice?

Re: Uninstall via custom action blocked by original uninstall

Perhaps a vbscript could be launched at the very end, as opposed to an installscript, so that when the second uninstallation starts, the first is already concluded.

Re: Uninstall via custom action blocked by original uninstall

I finally solved it.

LAAW_OPTION_NOWAIT instead of LAAW_OPTION_WAIT, and move it to the very end of the custom action sequence.
