Using Minion with non-admin rights on Vista

[despe]

Hello,

When I try to install the Minion client on Vista with admin rights, there is absolutely no problem : the install works fine and I can use the Minion.

But...

When I try to run the installed Minion with an other account (with non-admin rights) it has no module installed and in the "Options" menu there is only one menu : "Global Configuration" (I can not set the path to WoW install folder)

I also tried to run the installation process from the non-admin account, but I have this message :
C:\Users\xxx\AppData\Local\Temp\download-6726.exe
Service does not exist as an installed service.
