Question:

Answer:
For some reason the operating system is not recognizing that it needs to open a file with a .tcl extension with wish84.exe. Therefore from explorer open folder options, file types, and see if TCL is on the list and asscociated with ActiveTclScript and under advanced the open statement should trigger the following: “C:\Tcl\bin\wish84.exe” “%1” %*
