@andredr: You have installed SH5 to your "Program Files" folder, the first cardinal sin when using Vista or Windows 7.
You will find your mod files sitting in your VirtualStore\SH5 folder. If you do not know where that is, pls research UAC.
Seee
here for more information regarding JSGME. Pls note the Vista/Windows 7 Users section under "Installation".
@Webster: FYI common problems such as dupe folders will be covered in the above link when I get some time over the coming week.
