Error Loading runCIPClient.tcl

After installing the CIP client and starting OrCAD Capture, you see an error similar to the following in the Command Window.

Error loading
C:/Cadence/SPB_22.1/tools/capture/tclscripts/capAutoLoad/CIPClient/runCIPclient.tcl: can't find package Tk.

Cause: The most likely cause of this problem is that you have either a TCL_Library or TK_LIBRARY environment variable defined.

Solution: You will need to remove these environment variables. Further explanation can be found from the following link: https://wiki.tcl-lang.org/page/TCL_LIBRARY
