Troubleshooting: When installing Legacy I receive a Setup Initialization Error

Click on the Start button and select Control Panel and temporarily change the default language setting for your Regional options to English (United States).

In addition, sometimes files left in the Temp folder by other programs interfere with the Legacy setup. Delete the contents of the C:\Windows\Temp folder (or C:\WINNT\Temp folder), restart your computer and try installing again.

You should also temporarily disable any software monitoring software and anti-virus programs while you install.
