I am attempting to upgrade to PM15 Pro from PM11 Pro in readiness for W10 upgrade. The PM11 Pro user manual says >>In case there is some previous version of the program installed on the computer, the program will offer the user to uninstall it first.<< On that basis I understood this upgrade would be an in-place upgrade so I purchased the upgrade to PM15 Pro and downloaded the product Paragon-400-PRE_WinstallSNx64_10.1.25.377.000 When I attempt to upgrade I get a screen advising that PM11 has to be uninstalled using the Windows Control Panel Add/Remove programs be used to remove the earlier version My concern is that how can I safely uninstall PM11 when my "C" drive has partitions created with PM11 ? If I uninstall Partition Manager 11 will the partitions remain or will I be left in "limbo land"? Help please!
