Trying to launch TGRID after installing FLUENT 12 or ICEPAK 12 you receive this error:
Bad version number - must be floating point number, with no letters
FLEXnet Licensing error:-77,131
For further information, refer to the FLEXnet Licensing End User Guide
Comments: This is a bug caused by a newer license library that gets installed when you install either ICEPAK or FLUENT 12 after you have installed TGRID. This will be fixed at some point.
Workaround: The workaround is to reinstall Tgrid in a new location.
