The TrueType Font Assistant relies on font information recorded in the Win.ini file. The TrueType Font Assistant does not work because font information is not stored in the Win.ini file in Windows 95/98.
The Fonts folder is a system folder and is not included in searches. However, if you have installed the Windows Desktop Update component with Windows 98 or Microsoft Internet Explorer 4.0 or 4.01, the Fonts folder is searched by the Find tool. You may want to back up any file that you want to save and do a complete installation rather than trying to re-install.
