ISE 14.4 BitGen Failing After Vivado 2015.1 Installation

Question

My node-locked version of Embedded Edition ISE 14.4 has started failing Bitgen with the following warning:
WARNING:Bitgen:26 - Bitgen only supports DRC but not bitstream generation on
   this device.  This condition can occur if there are problems obtaining a
   license to run bitgen or if the design targets a device which is Early
   Access.
I have not changed my ISE license file recently, but I have installed Vivado 2015.1 in the last couple of days. Sythesis and Implementation still work. The License Configuration Manager that I can open from the Help menu still indicates that I have permanent licenses for all the features (i.e., nothing has changed to the best of my knowledge).
Could the Vivado install have messed up my ISE licensing? If so, how do I fix this problem?

Answer 1

Hi ,
Are there more than one ISE licenses in the installation directory?
Please attach the Xinfo file so that we can check if the correct license is being accessed by ISE.
 (also post the name of those .lic files)
To generate the xinfo file:
Start --> All Programs --> Xilinx Design Tools --> ISE Design Suite 14.x --> Accessories --> Xinfo System Checker.
Thanks,
Tushar.
