We currently do not recommend using the Internet Explorer web browser because the setup procedure can be significantly more complicated. Firefox, or Mozilla, or Netscape are much easier to configure.

Instructions for Firefox, Mozilla, or Netscape web browsers

1. Download and install the small standalone version of Fv. You must have version 4.3 or higher. It is recommended that it be installed in the default location at "C:\fv\bin\fv.exe".

2. Click on this 'Test Hera' link and carefully follow these instructions:
   • a brower window should appear that asks what you want to do with files of type XHERA or text/x-hera.
   • Select the "Open with" option, and use the "Browse" or "Choose" button to find and select the previously installed fv.exe file.
   • Also select the option box to always do this automatically the next time a file of this type is opened, if your browser provides that option.

If these 2 steps have been performed successfully, then clicking on the above 'Test Hera' link will display a new window confirming that you have successfully setup fv to run Hera.

If for some reason you need to reset the path to the fv executable, follow these instructions, depending on your browser:

• Firefox (1.5.0.1): under the Tools -> Options -> Downloads menu item, click on "View & Edit Actions..." select the line associated with the XHERA file type, and then click the 'Remove action' button.
• Mozilla/Netscape: under the Edit -> Preferences -> Helper Applications, select the line associated with "text/x-hera" and click the 'Remove' button.

  You should then be able to click on the above 'Test Hera' link, and enter the new path to the fv executable.

Return to the Hera Home Page.

6. Continue pressing the F3 key to search though the entire registry, fixing any other incorrect references to the location of the fv executable.
