#2 could be a viable option (I already have a Windows 7 testing machine in VirtualBox so it shouldn't really take long I guess).The workaround (not noob friendly, please do not PM me for support) is to do it manually using one of:
1. Another computer running Windows 7
2. A Virtual Machine instance (Parallels or VMWare Fusion) with Windows 7 installed
3. Using a Windows emulator (eg. Wineskin Winery on Mac).
You then install the game and patch, run the PESEdit D2 switch to a league of your choice (which will now work, as it’s only broken due to file access/security protections in Windows 10) and manually copy the now switched PES 2013 game and save folders and replace the same folders of your installed PES 2013 game on your main PC.
I’ve personally done this process via Wineskin Winery on a Mac, took all of 15 minutes - I’ve now got the Npower Championship working (instead of the default 2.Bundesliga).
Thank you!
