Just follow the instructions that came with phpBB 2.0.1 and run the patcher. Place the .exe in the same folder as the patch file, place the MODed phpBB2.0.0 folder in the same folder. Then use the same command lind as in the phpBB 2.0.1 upgrade installations.
Ok, I downloaded UnxUtils and I downloaded the patch file. Now I placed the patch.exe file in the patch dir, and I put my phpBB forum in that directory as well. When I run patch.exe and type in the command "patch -p0 < phpBB-2.0.1-update.patch" nothing happens. I know I must be doing something wronge. Is this the right file "patch.exe". I'm using a Win2k box and I don't have access to a Unix OS right now.
