On launching either the "compXlib" gui from the command line or by running the "Simulation Library Compilation Wizard", the GUI appears to crash with the following message:
This does not always occur and happens on certain Windows machines only.
This has been found to occur on machines where the environment contains "Aldec Active-HDL" in the PATH environment variable.
To workaround the issue please remove "Aldec Active-HDL" from the PATH environment variable.
An alternative workaround is to run compXlib from the command line, as this is a GUI specific problem.
For details on running compXlib from the command line, please refer to the Command Line User Guide on xilinx.com.
