The installation process is handled by a setup program that starts automatically when you first insert the DVD. You will be warned to close other programs during the installation. Icons for these items can be seen in the task bar. Be sure to temporarily close anti-virus monitoring software – it plays havoc with the installation of any new software. This software needs about 950 MB on your hard drive. This software also installs files in your system folder, such as operating files and screensaver files.
During later operation of the product, various files are written to your TEMP folder, such as .wav files from Spectrogram usage, .tmp files, and a TBS folder for media caching. You should clean out your TEMP folder periodically.
You should not uninstall version 3.9 if you have custom lists or quizzes that you created. After the installation of version 4, all your custom lists and quizzes can be transferred from version 3.9.
Following the successful installation of version 4, click File and then click Import from Previos Version. Please check to make sure your custom lists and quizzes are imported correctly. If everything looks OK, you may then use the Control Panel to uninstall version 3.9.
You can use the Windows Control Panel Add/Remove to uninstall the program. Look for it under Thayer Birding Software. You might want to do a backup of your sightings and custom lists if you intend to reinstall the software.
An uninstall does not remove the Thayer folder if you have any files in the sub folders that were not installed by the setup program. Examples include backup files you created or the media folder if you copied it to a hard drive.
