Answer: Here's how to install a new version of Foxhound while at the same time preserving some or all of your existing Foxhound data:

1. Run the Foxhound "unsetup" process: start - All Programs - Foxhound1 - Tools - Unsetup Foxhound

   This will reverse the actions of the original Foxhound InstallShield setup process, but it will not remove the Foxhound database from your system; see Why is it called "unsetup" instead of "uninstall"?

2. Run the new Installshield setup you have downloaded (see How do I install Foxhound?).

3. The post-setup process will ask how much data you want to preserve; just press Enter for ALL data:

   ******************************************************************
   *** You can control how much of the existing data is upgraded.
   *** To do that, you can set the FOXHOUND1UPGRADE environment
   ***   variable BEFORE running this upgrade process,
   ***   OR you can type in a temporary override here.
   ***
   *** The current setting is...
   ***   FOXHOUND1UPGRADE=ALL which means upgrade all the data
   ***
   *** If you want to CHANGE the setting, type in a new value...
   ***       ALL       - upgrade all the data
   ***       OPTIONS   - no samples, just the Foxhound options
   ***       yyyymmdd  - options plus samples since yyyymmdd
   ***       nnn       - options plus last nnn days of samples
   ***       NOTHING   - don't upgrade any data
   *** ...and press Enter to continue.
   *** You will be asked to "CONFIRM OR CHANGE" again.
   ***
   *** If you LIKE the current setting, just press Enter.
   ******************************************************************
   Current FOXHOUND1UPGRADE=ALL
   New     FOXHOUND1UPGRADE=

4. When you restart Foxhound you won't need to provide a registration key... unless you specified NOTHING in Step 3.

By default, Foxhound is installed in this location on Windows XP:

C:\Documents and Settings\All Users\Application Data\RisingRoad\Foxhound1

C:\ProgramData\RisingRoad\Foxhound1

Note: Before overwriting the current foxhound.db and log files, the post-setup process will move them to the backup\previous_build subfolder under the locations listed above.

Caution: If you are running Foxhound as a service, stop the service before installing the new version. The installation process needs to stop and restart the existing Foxhound database, and it probably won't be able to do that if it's already running as a service.

Caution: If you are using the Windows Vista or Windows 7 Task Scheduler to take regular backups of your Foxhound database using the technique described here, you should reboot your computer after installing a new version of Foxhound; see The $backup_foxhound1.bat file looked for a path specification in the FOXHOUND1 environment variable and it was empty.
