Instruction for Version 1.0.2
If your pes 1.02 exe file is around 40MB then:
Go to your temp directory: “C:Users*YourName*AppDataLocalTemp”
Start Pes 2013.
Now switch to the temp folder (pes must still run) and look for a file, with the typical pes icon.
The file must be around 19 MB. If there are more than once, just pick one with Version 184.108.40.206.
Rename the file to whatever you want and copy it to your Pes install folder.
With this file you should be able to run the game and also use this tool.
