Hi, this is for everyone who's experiencing the MD5 hash error at installation / patching.
I sent a ticket to the MWO support and got this reply with a guide that helped me very
much indeed, now it's installing and patching properly and seems to run fine.

Hello xxxxxxxxxxxxxxxx,
That error is generally a sign of a corrupted file in the installation. I would suggest a clean reinstall of the game. Please follow the steps below to ensure you don't run into any snags.
-Control Panel -> Uninstall MechWarrior Online
-Check install directories and remove any folders leftover
**Old Default Install path: C:\Program Files(x86)\MechWarrior Online
**Current Default Install path: C:\Games\Piranha Games\MechWarrior Online
-Clean up temp folders:
**C:\Users\*Your Windows Session’s ID*\AppData\Local\Package Cache
**C:\Users\*Your Windows Session’s ID*\AppData\Local\TEMP\MechWarrior Online
-Clean up registry keys with CCleaner (
http://www.piriform.com/CCLEANER)
-Run the application with the default options
-Clear your browser cache
-Restart the computer
-Download a new installer from mwomercs.com and run it.
Otherwise this can be a sign of a failing drive...
-Open a Command Prompt: Start -> All Programs > Accessories -> Command Prompt
-In the prompt, type in " chkdsk C: /F "
-A reboot will be required to properly check and repair errors.
-repeat those steps for any other installed drives, replacing 'C:' in the command line with each drive letter, one at a time
Regards,
xxxxxxxxxx
