Hi
If he really means Team Avalanches HighRes.exe and if he has a 64-bit Windows ,the error is in the MOD.
The installer looks in the wrong registry key, if Aalis driver is used or not..
But you can trick the installer.
Open the Registry Editor and look for the key
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Square Soft, Inc.\Final Fantasy VII\1.00\Graphics
There change the value for "Driver" to
3
Then install the "HighRes.exe" and then install "Avalanche GUI v2.0.8.exe".
