Why does the Intel® Quartus® Prime software fails to detect a floating license?

Description

In the Intel® Quartus® Prime software version 16.1 and later, you may see that your floating license is not detected. This occurs on slower connections between the license server and the client. The Flexlm version was upgraded to 11.13 and this version is intolerant to WAN latency.

 

Workaround/Fix

To work around this problem, adjust the FLEXLM_TIMEOUT environment variable in the client machine, the available range is from 0 to 2,147,483,647 microseconds. Default value is 100 microseconds. 

For example to set the variable to 1 second, set the variable as follows:

FLEXLM_TIMEOUT=100000000
