IDLE will not open; it does not give an error or even appear on the 
process list.

I am using Windows XP on an IBM Thinkpad. I tried the prescribed 
solution on Issue 4049, and it returned this message:

This probably means that Tcl wasn't installed properly.

I am very new to Python (and programming in general), and I have no 
idea how to fix this.

By the way, I did install the program for all users.

This is a duplicate of issue5528.
The fix is to remove the TCL_LIBRARY environment variable.
