I am able to confirm that on windows 10 pro. x64 the same issue that another user had, when trying to run swamp is indeed happening.
even when checkup.exe is ran, even when ran in admin mode, even when games coppied to desktop and ran from their, even when game folder is propperly extracted, and, even when progress.ini is deleted.
the game stil insists on erorr52 bad file name or number.
I am certain that it has to do with the inability to register some much needd files.
so i'll be looking in to this, and, once resolved, i'll post a solution here.
It is mildly frustrating that windows10 is being iffy about this.
if some one did manage to stumble on a solution, do let me know.
If not, i'll post back, once i've resolved this.
There's a place for me in this universe.
