Is this a patch or not. You don't seem to know if it is or not.
Is there a patch to iFlySetup-10.3.53-Windows.exe?
Update: I just checked the version installed. it states it is 10.3.52 although the version I downloaded 10/4? file name states it's 10.3.53.
I installed the iFlySetup.exe just now and the version installed it is still 10.3.52
