RoboForm2Go for U3 Drives
RoboForm2Go: RoboForm Toolbar on a U3 Drive
U3 support has been discontinued.
This happened because U3 standard has been abandoned and U3 consortium is not operational. The last version that supports U3 is: RoboForm2Go for U3 ver 7.4.0.
How to migrate.
Just install regular RoboForm2Go (not for U3) on a regular (not U3) USB disk.
Download the non-U3 version.
