Thanks Denise,
I have attached the Belarc report pages and a capture of the error when attempting to run the install which says that you must uninstall any version 10.1.3035 products before installing ArcMobile v10.
The Belarc report will show I have ArcMobile v3 on there, that wasn't on there when i tried to intall ArcMobile10 so that is not part of the problem.
