Installing FlashGet
Download the FlashGet installation package if you haven't already. Extract all files from the package into a temporary directory using your archiver, such as WinZip. On Windows NT and Windows 2000 systems, login with Administrator privileges. EXIT ALL RUNNING PROGRAMS. Run SETUP.EXE and follow the instructions. Now it is safe to delete the installation files. You may want to keep the zipped package in case you need to reinstall FlashGet later.

Updating FlashGet
When updating FlashGet, do not attempt to delete any files of your current version, especially default.jcd. This file contains all the information pertaining to your queued downloads and download progress. If deleted, the download jobs will not function correctly. If you install FlashGet in a different directory, it uses the database you used last time (usually default.jcd in the folder you installed to last time). Don't use two versions of FlashGet at the same time, because changes are made to the structure of the database in every update. It may corrupt the database if you use an old version.

Uninstalling FlashGet
We can't imagine why you'd want to, but if you're feeling silly, FlashGet uninstalls just like any other application: Click on Start, then Settings, then Control Panel. Now double-click the Add/Remove Programs icon in the Windows Control Panel. Select FlashGet in the list of installed programs and click the Add/Remove button. Follow the instructions. Voilą! FlashGet is gone. If you've been overzealous and already deleted the FlashGet files without uninstalling the application the usual way, use the UNREG.INF file to remove the registry keys responsible for the browser integration. You can find this file in the distribution package or download it directly from http://www.flashget.com/unreg.inf. Right-click on the UNREG.INF file in Windows Explorer and select Install in the popup menu.

FlashGet will remove "download all by flashget" and "download with flashget" from IE's context menu, If not run regedit.exe delete such registry item
