My 1.22 patch was giving errors...The error said something like 'Path not found...' ...It wouldn't even apply...I tried everything until i went to some site that helped me out....

Go to 'Run' and enter 'regedit'... Now go to HKEY_CURRENT_USER>Software>Blizzard Entertainment...Now right click Warcraft III, go to new and enter string value... Name the new string "InstallPath" <---Exactly like this, without quotations.....Right click the new String and click Modify....Here, type the address of your Warcraft e.g. "C:\Program Files\Warcraft III".

Note - Just enter the address of the FOLDER where warcraft is...Dont enter the address of the any file in it E.g. "C:\Program Files\Warcraft III\war3.exe" or "C:\Program Files\Warcraft III\Worldedit.exe" <---Both are wrong Now,

Install the patch and it should work like a charm =D...Plz lemme know if it works...
