Cannot install/uninstall Microsoft Mouse And Keyboard Center!

Hi, i was having trouble with the Microsoft Mouse and Keyboard Center because it didn't identify my Touch Mouse correctly (listed it as HID-compliant device and not by its name like my Sidewinder X4 keyboard). I uninstalled it from Add/Remove Programs and i also uninstalled the drivers for my mouse AND my keyboard (because it showed a Dual Receiver Device in device manager). I rebooted my computer but when i tried to install the drivers again through the Mouse and Keyboard installation process i got an error message telling me that it was already installed. I uninstalled it again ( the "ghost" of it was still listed in Add/Remove programs) and rebooted. When i tried to reinstall it i got again the message that was telling me that it was already installed. This is when the weird stuff began happening. The program was once again listed in Add/Remove programs (this time with its icon and not just a "ghost"). I tried to uninstall it and got a message telling me that the uninstallation process could not procced because some files of the original installation were corrupted or missing. But now the program was listed in the start menu of Windows and when i double clicked it it began an installation process which stopped immediately returning a message that mkc.msi was missing from a temporary file of My Documents and it could not proceed, So now i cannot neither install nor uninstall the damned thing. I tried to roll back my computer but it didn't solve any problems. I suspect that some registry entries weren't deleted properly during the first uninstallation process. I don't want to mess with the registry by myself at least not until i am sure which registry entries are created by and related with the program. Any help would be appreciated.

Thanks in advance
