That didn't help. I've downloaded it, changed it to Run as Administrator on the Compatibility tab, and run it.
Let me be clear about what I'm doing:
1. Start 7D2D Mod Launcher
2. Click the Browse for Folder icon on Destination Folder, and change it from C:\7D2D to D:\GAMES\7D2D
3. Exit
4. Start 7D2D Mod Launcher again
I expected Destination Folder to be pointing to D:\GAMES\7D2D, but it is pointing to C:\7D2D again. I have installed mods on D:\GAMES\7D2D, and they are there. Once I change the destination folder, they show up again.
One thing I don't think I ever did was to actually start any of the mods, as I'm waiting for them to update to 16.4.
