I've seen multiple threads about this.
The error that i seem to get while others do to, while decompressing the patcher will pop up an error at 99% while decompressing and it will say "Error patching, would you like to do a recovery" and that still does not fix anything...
I've seen people say that going and finding the launcher.exe running it as admin works, but alas it did not for me.
I do have updated dot net framework... Im running Win7 64bit.
My last computer ran it perfect (minus the lag due to hardware issues and not being up to date) after getting my new computer and wanting to try GRO out with this beast it keeps popping up that error...
I've tried unistalling several times, tried redownloading more than i can count and to my avail still not working... has anyone found a legit fix that works?
*Also i've sent in a ticket so before someone tells me to or asks me to i've done it already just want to see if someone on the forums can beat them to a fix*
