Thanks guys! There is a reason I always come to this site first.Ok here we go....
These errors are commonly caused due to memory errors or incompatability.
If you have two memory sticks try installing with only one by swaping each on each installation if it is still not working. try to change the sticks and see if it works
Had a system that was massively messed up because of an anti-virus issue, so tried to do system restore. System restore failed repeatedly, so tried to do clean install. Clean install from USB didn't work with x64 or x86 versions that I have, although both have worked before. Kept getting 0x80070017 error even after wiping HD etc. Was about to jump out a window. Then tried the RAM swap, and it works!
If you are having the 0x80070017 error on install, take out a RAM stick and try again, then if it still doesn't work, try the other one. It works!
You guys saved my sanity again
