@abobobilly, thanks for the invitation for help, I am extremely busy with my upcoming exams its difficult to find time to work out a solution for this problem. (and vista was never an OS that I installed more than once).
But it seems that WMF(water mark factory I presume) has problem with vista, though not many but a few user have put up same problem on some of the discussion boards. Here is a link to a board where a user has pasted the same problem, but please do understand some of the contents on this board are not meant for under 18 people.

Apparently there could be two issues
one the antivrus/windows might have identified the program as malware and blocked it permanently (less likely) and
(more likely) Secondy the software might have compatibility issues with vista and hence must be re-installed in xp compatibility mode, but before reinstallation it must be unistalled not just simple uninstalled, but removing every instance of the program from registry as well (and that my friend is a huge risk for novices)
BTW as far as the probelm of legit Vista is concerned and not having the DVD, find a little program called keyfinder, run it and save the serial number of vista, so that if your installation of vista runs into problem you could reinstall it with any other dvd.:signs069:
Even then if the problem is not solved post again and I ll try to help, but please do understand my exam is on 19th and 20th march and I have to travel to USA as well so finding time will be bit of an issue for me. as far as the error WMF has stopped working it is simply telling that due to one reason or the other "Water mark Factory" has stopped working, if you are connected to net click the option saying "close the program and look for an online solution" see what happens, Post that as well (hopefully it will go to MS website and try to find a solution) (HIGHLY RECOMENDED)
