FreeFileSync Forum

That was not the issue. If FFS is installed into C:\Program Files\FreeFileSync, and I executed the direct access from the desktop (I suppose it is the 32 version) , ffs can’t create any file in my computer. I checked it and only if I run the 64 version I don’t have any problem.

Problem solved:

I run my FreeFileSync in a Windows 11 machine and I´ve been dealing with this ERROR_ACCESS_DENIED problem bc i changed the letter of the disk where FFS was installed.

Long story short: Don´t open the FreeFileSync.exe file: instead go to the bin directory and execute FreeFileSync ...
