Support directed me to post here, so hopefully there's an answer out there... I installed ExtFS recently to try and access my old Linux partitions. When I run the utility and tell it to map a drive, I always get the response "Error. Selected letter has been assigned". This happens if I run it as myself or an administrator (although my account also has admin rights). It doesn't matter what letter I pick, I always get the error, and non of the letters have been assigned to either a local or network drive. Secondly, I tried to uninstall it thinking it might not have installed correctly for some reason, but it does not show up in Add/Remove Programs. If I run the installer again (as admin and not), it appears to do nothing. All options are greyed out, so I can't pick to reinstall the drivers or app. Even after reinstalling, it still doesn't show up in Add/Remove Programs. I'm on Windows 7, 32-bit, all up to date. I'm at the office, so not sure exactly what version of ExtFS, but I just installed it last week with a fresh download. Final note: I've already rebooted since installing and since having issues. Thanks.
