Silent installation problem by macrus on 06-20-2005 at 08:02 PM
Hello
I have problem with unattended/silent installation of MessengerPlus by group policy. I use a script that is run on system startup (before logon) that first checks if msgplus.exe exists in any of typical directories, then runs installation from a network lacation with option /SilentInstallNoSponsor.
Everything is fine until the installation finishes and Messenger window is launched. Notice that it appears _before_ logon screen and installation somehow stalls (it is: Messenger window can be normally accessed but the script stops). Even if I close Messenger window, the script does not continue progress and startup is hanged until GPO script processing timeout comes (10min).
Additional problem is that this appears to be a security issue also - MessengerPlus has features (like task scheduler) that allow access to the system without logging in! I just ran Explorer from it and normal desktop appeared with enough rights to access anywhere ...
I know I could put the installation into user login script but I prefer it to be user-independent...
What is also strange is that some time ago, when I created all this automation mechanism (around version 2.5x I think), it worked...
Is there any other switch or way to prevent Messenger from launching after installation ?
regards
Maciej

This is not a script problem - there is nothing else in it except msgplus installation - from "script's point of view" the installation is not finished (control is not returned to the script) - so it hangs exactly on the line where the installation is launched
BTW: MessengerPlus installs correctly, even if the script is forcibly terminated by the timeout.
I found out some workaround...instead of calling setup directly I use "start" command so the setup processes paralelly now. However, I had to put to the script a command that waits 60s to give Messenger Plus time to install itself (otherwise the installation fails). I don't like this workaround however I can't find any other way for now...

Thank you for reporting. The problem has been "fixed" in the next version by not starting Messenger automatically at the end of a silent installation (it's supposed to be silent after all 
).
