Hello,
I just reinstalled powerpoint from microsoft office standard edition, running on windows xp. When I open power point I am asked for the product key. I enter the product key and another window pops up saying product compliance check (setup failed to locate a valid qualifying product on your machine. please select the drive where the qualifying product can be found). So I've tried every drive on my computer and I always get Error 1608 (setup unable to locate a qualifying product). What should I do? Any help would much be appreciated!
Thanks
