need some advice about registry uninstallstring

[Nerd1337 0]

I am having problems running a script that I wrote. Mainly I am trying to uninstall AVG 7 with my script so that there is no user interaction. However, I am not sure how to run the uninstallstring if the path that the uninstall program is anything other than C:. When I try the following, it works perfectly fine.

Run ("C:\Program Files\Grisoft\AVG Free\setup.exe /UNINSTALL")

However, if I run the following, I get an error about how it can not execute the external program and I have to kill my script.

Run ("%SYSTEMDRIVE%\Program Files\Grisoft\AVG Free\setup.exe /UNINSTALL")

If you have any advice or any ideas pleace let me know. Also, I see that there were marco references, but I am unsure of how to use them, or even if they would help me in this area. If I could either get examples to these, or be directed to some, I would greatly appreciate it. Thanks a bunch!

[/dev/null 2]

Run ("%SYSTEMDRIVE%\Program Files\Grisoft\AVG Free\setup.exe /UNINSTALL")

%SYSTEMDRIVE% is not expanded. Use this:

$systemdrive = Stringleft(@Systemdir,2)
Run ($systemdrive & "\Program Files\Grisoft\AVG Free\setup.exe /UNINSTALL")

Cheers
