Problem - license manager doesn't start when vendor path includes spaces

A client detected a problem by looking at the license status report using the LMTOOLS user interface.
Even though there were no errors when starting the license manager itself, the status request generated the following license errors.

Users of ACS5II: Cannot get users of ACS5II: No such feature exists.
Feature:       ice-pro
License path:  1500@barley1500;
FLEXnet Licensing error:-5,222
For further information, refer to the FLEXnet Licensing documentation,
available at "".

Why would this occur?

The error occurs when the vendor path name includes spaces. Here is an example of the problem:
VENDOR artwork C:\Program Files\Ansys Inc\Shared Files\Licensing\artwork.exe


Enclose the path name in double quotes. Example of solution:
VENDOR artwork "C:\Program Files\Ansys Inc\Shared Files\Licensing\artwork.exe"
