When I try and install Windows 7 service pack 1, I get an error that halts the install (code 80073701).
I've looked around quite a bit, and a lot of places say that a language pack may be the culprit, and suggested running lpksetup.exe and seeing if there were any (corrupted) installed language packs. I ran this and it appears my English language (default) pack is corrupt.
Is this most likely the issue, and if so, is there a way to go about reinstalling the language pack?
Best Answer
I do not believe your language pack is corrupt. I setup a Windows 7 RTM machine (no SP1), and ran lpksetup. The window was the same as your screen shot. I cancelled out and was able to install SP1. I think lpksetup is just warning you that you only have one language pack, so maybe you don't want to remove it.
