If Iopen the PlanAhead tool (or other Xilinx application), the following error occurs:
"PlanAhead - System Error: The program cannot start because libxercesc.dll is missing from your computer. Try reinstalling the program to fix this problem."
The libxercesc.dll file is correctly found when I check the PATH.
> which libxercesc.dll
Echoing the PATH variable from a command window shows a valid PATH. However, if the PlanAhead tool is launched in Tcl mode (planAhead -tcl), the echoing PATH from the Tcl shell returns "C:\Windows\system32\NV;.;;.;"
Why is my PATH variable being changed/truncated?
What can be done to fix this issue?
This issue appears to be isolated to Windows 7 computers with the following conditions:
Changing any of the conditions above resolves the issue. Disabling Optimus in the BIOS is typically the preferred resolution.
Another workaround found to work is to remove the original NVIDIA drivers and re-install them. After re-booting,the tools work properly.
