im sorry pyccna, but thats really impossible. The odds of the right bits being changed just to change the 1000 to 100, and no other data being corrupted would be impossible. If you have a download "Glitch" the intaller would most likely not run but if it did run it would error in the middle because of a in consistancy in the zip files (the downloader loads a zip and creates a gui overlay for ui purposes). And assuming some how it didnt affect the installer, the data that got corrupted would be spread across multiple file, because this is a zip encryption. But assuming some how that the only file touched was the exe, just one bit of data being corrupted (not even remotely possible).
This all assumes that fttp ever corrupts files, which again would be nearly impossible.
