If you too experienced these issues, follow the steps listed below:ġ. I found a workaround that enabled me to bypass this issue with the License Manager and run ISE 14.7 on Windows 8.1. Specifically, many users including myself encountered instability in the Xilinx License Manager (xlcm.exe) that made it impossible to validate a Webpack License therefore rendering the ISE tools unusable. Unfortunately for me, and many other Xilinx users, the ISE Design Suite 14.6 Webpack Edition was not supported in Windows 8. Get Xilinx ISE 14.7 Webpack to work on Windows 8 I havent tried this for versions older than 14.5 so just be forewarned that it may not work for versions older than 14.5 This can be used for 14.6, 14.5, etc.just change the revision number.
I ran into this problem on my new Windows 8 machine and came across this solution in my journey to locate a fix (see attached file). exe files you need (either _pn.exe or _xlcm.exe). For those of you who already have, are going to, or are going to against your will, migrate to a Windows 8 machine and intend on using the Xilinx ISE tools you are likely to have an issue run the software.
