Hello.
I have checked on a clean machine (Win7 in Oracle VM VirtualBox) without any additional program, But the error still apears.
I'm sure File size is general problem.
Thank you.
I checked and all my setting is correct(as you said).
in installation progress all files copied in Data directory except common.MPQ.
I think the problem is the file size.
I Have this error in log file.
Error 1310. Error writing to file: C:\Program Files\MyPack\WtW\Data\common.MPQ. System error 131. Verify that you have access to that directory.
common.MPQ file size is: 3743138KB
there is no problem on XP
