It isn’t the installer you have to trick it is the OS as that is what determines what are fixed and what are removable drives I believe. So if mounting the SD Card option you found would work that could save a lot of grief, otherwise you are left with trying a move.
Before even trying this you would obviously have to disable the avast self-defence module as that would block any attempt to do this. Though I don’t think it is a simple matter of moving the avast software folder to another location and changing the registry references for any instances of C:\Program Files\AVAST Software\ to G:\Program Files\AVAST Software. I don’t know if there are any internal references to locations.
Is this actually an SSD drive inside or just Flash Memory, If a very small SDD I don’t know if these could be upgraded and how much it is likely to cost.
