Upon installing 5.1i, my already existing and working Modelsim can no longer find the dongle.
This can be verified by running "lmutil lmhostid -flexid" from a command prompt.
Rather than the expected "Flexid = 8-<some hex number>" it returns "FLEXID=7-0".
Try reinstalling the drivers from the modeltech directory, as follows:
for a Dallas key (the ones with the hole in the middle), run
for the Sentinel key, run
You'll need to reboot afterwards.
