x200 tablet multitouch

[tomy66]

hi, this is my first post in here and it concerns x200tablet (7450 aj6). The problem is multiouch or no multitouch. I have only touch by pen, there is no finger touch. I tried to install latest software on windows 7 and 8 (both 64x) but it doesn't help at all. So my question is about how can I install multouch and eventually wich system is the best choise for this tablet. If you have any suggestion, queries or whatever else just read. I will be grateful for any help.

Are you sure the tablet is one of the multitouch ones? If you look up the parts using your serial number at http://www-947.ibm.com/support/entry/portal/parts what part numbers does your screen have?
