Thanks. If anyone's interested, here's a C-dilla killer batch file I worked out. Point your Mathcad startup shortcut to the batch file instead of the executable. Edit the start line to point to your excutable. Try adjusting the time delay (6000) if C-dilla keeps running. Works for 2000i. Others might have a different version of C-dilla to stop. Mathcad works fine without C-dilla once it's up and running, but won't start up without it present. Later.
@echo off
start D:\MathSoft\Mathca~1\mathcad.exe
echo Wscript.Sleep 6000> sleep.vbs
start /w wscript.exe sleep.vbs
del sleep.vbs
