1. Use WinRAR to uncompress the files. 2. Both versions contain the unchanged books. 3. Pre-1978_Books_Only.rar contains only the unchanged books. 4. Vedabase2003.rar contains both plus letters, transcriptions and lots of other stuff. 5. Vedabase2003.rar installs from anywhere. 6. Pre-1978_Books_Only.rar assumes that it's in the root directory, so you have to copy the uncompressed files to a newly formatted USB flash drive in order to install it. 7. VedabaseFonts.rar is only needed if you are using Windows Vista or Windows 7. When installing using Vista or 7, use Windows XP compatibility Mode. After installing the VedaBase, copy the fonts to C:\Windows\Fonts. 8. After installing using Vista or 7, run the VedaBase and click "Tools / Options..." Then enter "ScaHelvetica" as the "Infobase view font / Name:".
