I've been running into the same problem quite often recently, Error 800703F1.
I saw your article on the steps to solve it, but it wouldn't execute the command "%userprofile%\Desktop\cbs.txt"
Any idea on how to fix that? Alternatively I opened the file in WordPad and uploaded that to wikisend, but I'm not sure how to send that on this website.
Thanks for your help, hope to hear from you soon!
