Temporary file needed for initialization?
 

Ok downloaded it to my documents i think it's my antivirus wrecking havoc but the error i get in starting it says "Temporary file needed for initialization could not be created or could not be written to. Make sure that the directory path exists, and disk space is available." Space isn't an problem so it has to be the pathing. Any ideas? I like the look of the new maps that i can see with the regular expansion but if they aren't accessible for all the zones and can't update them, what the heck? Please help! Thanks in advance :)

Might be that windows prevents the installer from creating a temp file, try run it as admin if you use vista.
