[wpkg-users] Trouble moving a PC to a different profile...

Hi Marco,

Let's first have a look at the VLC issue:

This is a well-known issue of the VLC installer and also documented on wpkg.org.
The uninstaller forks a process and then terminates the initial uninstall.exe
immediately. Thus leaving the uninstall entry there. As you can see WPKG reports
that VLC is still installed and therefore enters zombie state (installed but not
assigned to host).

In order to prevent this you need a more smart uninstall command. The script
attached can do that for you. Rename it to unattended-uninstall.cmd, fill in the
values in the header of the file (correct paths) as required and then call this
script instead of the uninstall.exe binary. The script will wait for the
uninstall process to finish its job before it terminates and as a result WPKG
will detect that VLC has been uninstalled properly.

These ones seem to report that uninstall failed. Most probably the checks oyu
defined are still true after uninstall (or you did not specify any appropriate
uninstall command). Make sure the checks will fail after successful uninstall.
