So, a few days ago, there was a big deal about people not being able to patch their SC2 clients. I, however, was perfectly fine. I think this might have something to do with me patching 9 and 10 at the same time. Today, I was forced to System Restore to April 20th, due to a complete loss of my settings and some other stuff. One affected program was SC2.

Now, that said, I've tried re-patching by both using the SC2 patcher (slow as hell, torrents don't work on campus) and Maged's direct links. However, I keep getting this error:
The patch "pc-battlenet-hdfiles\Support\Battle.net.dll" could not be applied. (Invalid source file size: expected 13684763, actual 13924693.)

I don't know why it's not accepting my DLL file, especially because I'm not downloading a new one. I certainly haven't modified it myself! I can also confirm that Patch 8 was installed properly, since SC2.exe tries to download 9.

Is there any quick insight into this? Otherwise, tell me the info you want, and I'll dredge it up.

Hello Mjolnir

system restores only affect certain system files, not every program on the computer.

As such if a program has been altered after the restore was made than you may have issues running that program if you are restoring to a date prior to that change.

In this case what is probably occurring is your registry keys for the game claim you are using one version where as the game is actually a newer version.

Currently the only way to resolve this is to reinstall the game.

You will also want to do a disk defrag after the game is uninstalled.

No, not currently. world of Warcraft has a chance of getting it to resolve by using the repair utility and doing a revert but even that fails more times than it succeeds.

Just for the record. Maged might be trying to walk you through something we do not support but Maged is really helpful around here and in the old Battle.net forums.

He knows his stuff.

Do me a favor and report anything you find here in this thread.

I am going to send a link to one of my cohorts because he might be interested in what you guys find.
