I have been trying to uninstall the new version of Sony, but it isn't showing up in the CP in the uninstall section.

When I try to download it I get a message telling me that it is already installed. When I go to C: drive I can see it there but am unable to uninstall it from there.
I had the old version installed and then installed the new version, which seemed to be working fine. However I had a system crash and since then Sony has not co-operated at all. Adobe Digital, Overdrive and MS Reader are all fine.
I had been trying to follow autumnsong's advice, but am unable to find the program in the Add/Remove Programs.
I'm sure that I must be doing something really dumb, but haven't had a light bulb go on in my head today!
I will keep searching on MR for more info, but so far haven't found exactly what I can use to help me.
Thanks
Jen
