First edit the Icon that GME created in the desktop.
Move the cursor to the icon and press the right mouse button and choose Proprieties.
On the Shortcut tab you'll see an option named Start in:
Edit and change to the local address where you installed Panzer Corps.

Minimize the program, open the Windows Explorer and copy to the MODS folder (in your Panzer Corps main folder), the mod you wish to install.
Remember that the files must reproduce exactly the Panzer Corps file structure. Copy all the mods you want.
