As a check I re-downloaded the "UAW160Multiplayer13thJune.exe", ran it and then ran the "July05Patch.exe" in the "UAW160 Multiplayer" folder.
In the folder there is a "DSP2020MultiplayerV2.exe" file-manager program which allows you to select the exe that you want to use, the plane-set and the theatre.
I need to know if you can run it, or if you get an error message when you try to run it
