12.4 CORE Generator - ERROR:sim:764 - Could not attach readme viewer to a GUI process

Description

I receive the following error in the CORE Generator GUI when attempting to generate any IP core, regardless of core or device chosen.

Launching readme viewer...
ERROR:sim:764 - Could not attach readme viewer to a GUI process.
ERROR:sim - Failed to launch readme viewer.

Solution

This appears to occur when CORE Generator is evoked using the "wincoregen.exe" executable.

The following workarounds should resolve the issue:
    • After running "settings(32/64).bat", evoke the CORE Generator GUI from the DOS command prompt using "coregen" or "coregen.exe" and not "wincoregen.exe".
    • You can also open a 12.4 compliant DOS command window from the Start menu -> Xilinx ISE Design Suite 12.4 -> Accessories -> ISE DEsign Suite Command Prompt and then type "coregen" or "coregen.exe".
    • Alternatively, you can evoke Coregen from the Start menu -> Xilinx ISE Design Suite 12.4 -> ISE Design Tools -> 32-bit Tools/64-bit Tools -> CORE Generator.
