WLE 2011 won't Install

I get error 0x80070643 now

I tried DLing it from the site, from FileHippo, nothing works. I'm going to Restore my PC and see what happens

Well its nearing night for me so ill be off here soon. Someone else is likely to pop in. Good luck let us know how it goes.

Did a complete Factory Restore. Normally I'll run Norton Removal Tool, Install NAV 2011, Comodo Firewall, PC Decrapifier, then start putting my programs and songs on here. WLE was the very first thing I did and it worked. Now begins the 90 minute task of re-installing 7 SP1
