Trying to put Win7 on my secondary system with my upgrade disks (have both 32bit and 64bit) with no luck as the DVD or the CD drive won't read the disc at all. Other CDs/DVDs read fine.
Just copy the disk to an USB drive and run it from there. It's how I installed W7 on my laptop after noticing that it wouldn't recognise any of the disks I burned.

If the lot numbers/codes are correct, then yes. MSFT has done this before where they release different series of install discs, and the auth codes will only work on other discs within that series.
That said, Win7 probably hasn't been around long enough to have too many different series/pressings made, unless they started right off and split codes/lots up geographically.
