Why are the DSE II remote compile and exploration options greyed out?

Description

Due to a problem in the Quartus® II software version, you may see the Design Space Explorer II options for remote compile and exploration are greyed out. This problem occurs when the tool tries to write to a read only location.

Resolution

To work around this problem, set the following environment variable to prevent the tool from writing to this location.

For Linux: export PYTHONDONTWRITEBYTECODE=1

For Windows: set PYTHONDONTWRITEBYTECODE=1

This problem is scheduled to be fixed in a future release of the Quartus II software.
