Unable to start due to "Invalid Platform". Help for 64 bit system? [Solved via validation]

[Ultimatenewb13]

I've gone through several forum posts on this subject and all people are suggesting is to upgrade the OS from 32 bit to 64 bit and nothing else. It doesn't help anyone who's actually on a 64 bit system. Is there anyone out there who would actually be able to help in some way?

I've had this game for over a year or so now and apparently a recent update somewhere screwed with something, making it unable to start at all. Assistance is greatly appreciated.

I'm revalidating the files as a precaution while I type this, so the problem might be fixed there. Fingers are crossed, but not keeping my hopes up.

Edit: File validation ended up working.

There were a couple instances early 2016(ish) where the antivirus, corrupt windows OS / updates, etc caused this. By FAR though... 32bit OS / lack of 64bit was the issue.
(and 1-2 of them were a 64bit cpu, not OS.. anyways...)

I'd point to problems with your os, drivers, background programs. Verify cache is typically the default goto on anything - before even searching. Could probably try cleaning registry or a sfc /scannow and see if those correct anything.

Additionaly - a year? - did you previously use any mods? Can easily "verify/clean your folder" by deleting any file in the GTAV root folder that IS NOT A .RPF file AND is NOT a folder. Then verify cache. (and on some.. systems *cough* sometimes files there are hidden /smh)

Edit - looked in my history for recent posts. Early Aug - both had redone hdd with 32bit =\

OS, cpu, whatever it's supposed to be. I haven't had to do many of these, so the correct terminology isn't fully set into my vernacular yet. I can understand it just fine, but the wording on my end isn't always right.

I did an sfc /scannow with Overwatch about two weeks ago because I was having a similar problem with that from the Blizzard app. Didn't come up with anything, and an update on the game later in the day ended up fixing the issue, so I never figured out what to do to fix it. Also cleaned out cache files in both the Blizzard app and the Overwatch folder, but neither made any difference.

I haven't modded the game at all in the entire time I've had it (I estimated a year or so. Probably longer. Didn't want to take the time to figure out a more precise timeframe), so that's off the list.

I almost want to blame it on the new hard drive I moved all my games to. I had been working off of a 2TB Western Digial external drive, but that was starting to crap out and fill up, so I recently upgraded to a 6TB WD external drive. So far I've only had issues with Overwatch and (now) GTA V.

Edit: The file verification ended up working. I posted here before it finished because it tends to take a little bit and I didn't want to waste time only to potentially find out there was nothing to reaquire. Thank you muchly for your help, though.
