How do I address startup problems after upgrading from Mathematica 3.0 to Mathematica 4.0?

When upgrading Mathematica® 3.0 to Mathematica 4.0, there may be problems with the installation of the Math fonts that can cause startup errors. For example,

http://support.wolfram.com/mathematica/systems/windows/nt/startupfonts.html

You should do the following.

•	Delete all the Math* fonts in the Fonts Control Panel (using the Fonts applet in Control Panel).

•	Using a command prompt window and not an Explorer window, look in the system font directory and verify that all math*.ttf files have been removed.

•	Reboot the machine.

•	Using the Fonts applet in Control Panel, install the Math* fonts in C:\Program Files\Wolfram Research\4.0\SystemFiles\Fonts\Windows. (Be sure to select the Copy fonts to Fonts folder option.)
