So, after playing this game for 2 years, installing every patch without the slightest error, I had to reinstall Windows 7 2 days ago. After that I installed MWO and played fine until now. After downloading 50% of todays patch I get the message:

"The downloaded file is corrupt. The MD5 hash tag of the local file doesn't match that of the file on the server. Would you like to retry?"

Needless to say that "retry" does not solve anything, but wastes another 15 minutes of my time until the error pops up again.

Too bad the error message does not tell me which file is corrupt. So I 7-zip test all MWO files and found 3 .paks with 0KB size. Shaderscache.pak and such. I guess this was caused by the crashed Patch Install before. I downloaded the latest 3 .pak files from the MWO servers and replaced the 0KB ones. Checked all pak files again, found ZERO errors. Restarted patcher, after 50% same error message.

I read a lot of posts now with many different (sometimes weird) "solutions". Almost all refer to 64-bit Windows, I run 32-bit Windows 7 Premium Home Edition (always used this with MWO). Yes, I use Antivirus software (Avira Premium) and I am NOT going to switch off antivirus because a game patcher doesn'ty work properly.

I guess I will have to reinstall, then? What do I do if the error persists? Any workaround that actually works? Most posts about this are years old.

I know that individual pc issues are a pita for developers and hard to reproduce/fix. But they usually don't come from thin air, I had my computer running for 2 years with no issues. I only reinstalled Windows because I wanted to have 2 partitions, one with Windows and programs, one with pure data files. What could have caused the problem now?

Did you try running the repair tool instead of the normal client to patch the game ?

[Allen Ward]

Not yet, I will try. 90% of people I know tried it (to fix other probs) and it didn't do nothing. But it's worth a try, although it takes as long or even longer than reinstalling.

Please let us know whether the repair tool works or not (and if it doesn't, please submit a support ticket)

[Allen Ward]

Just finished running it (took about 30 min). It came up with the suggestions:
With the current options, clicking 'Fix' below will:
-Resolve any mismatched (invalid) files.
-Remove unneeded local files (if any were found).
-Clean shaders
-Clean local cache of FE images (fresh image will download the next time the game is run).

I clicked fix, it started downloading .pak files. After about 8 of them it crashed, showing a generic windows problem message. Not good. So I try to clean the system now and make a full reinstall...sigh.

One hour later. I uninstalled MWO. Checked for remaining folders/files (nothing). Used CCleaner, also on Registry (everything ok). Restarted windows and started to download MWO client again. After downloading Patch 1/1 (saying Download complete!) the progress bar stops at 50% and the dreaded MD5 hash error pops up again. WTF!

When I restart the client, it says PATCH again, starting at zero. Come on...

[Ironwithin]

You said you won't but at this point ... try turning off your AV software for the installation and/or running the client as administrator.

[Allen Ward]

I will. Just started patching again without Avira Pro. Takes another 35 minutes. Going to bed now.
PS: I always run the client as Admin.

MD5 Error for me again, on patching, which I'm pretty much expecting. My solution is to run the repair tool. Which crashes. Then I run it again, and it makes it a little further, then crashes. I repeat until it completes, at least 10 times. Then I play!

Repair Tool crash count 1,...

Thank you, that did the trick! I deactivated Avira Pro (Browser Security and Instant Scan) and after that the patch completed without error. Thanks a lot, it helped at least on my machine. Does MWO use some sort of hack shield? I only heard about similar problems with other games that use something like this. Probably the whole MD5 hashing idea ist not the very best, never seen it in other games (maybe because there no errors came up).

So now I have to reset all my settings and can play. Thanks for all advices here.

Not cool.

[Ironwithin]

Happy to help.

From personal and second-hand experience I can say that Avira tends to be very "uptight" about what it will allow to run and what not.

[Allen Ward]

Strange thing is that I installed MWO without any problems a few days ago - with AVIRA active. Now, with the patch, I had to deactivate it, before I could reinstall. I hope I don't have to deactivate it for every patch from now on.

Are you, by chance, running Avira ?

Nope, but I am running AD-AWARE

However, after watching the stupid thing fail over and over, and trying many things I finally said SCREW IT, and tried the FIXER thingy, which worked.
