Software Requirements and Installation

You must have Microsoft Word version 2003, 2007, or later to view and print out the Improvement Options Report.
Your operating system must be Windows XP or later. If you are using Windows XP, your installation must have at least Service Pack 2 installed. To install the most recent Windows XP Service pack, go to the Windows XP Service Pack 3 web page.
Click the button above to download the setup program for the AkWarm 2 software. After clicking the button you may be able to directly "Run" the setup program or you may be forced to save it to your hard drive. If you save it to the hard drive, you should then "Open" the saved file or double-click it to start the installation program.

Important Notes

For some computers, the installer will first install the Microsoft .Net Framework 3.5 Service Pack 1 (SP1), which could take as long as 40 minutes on slow Internet connections. All installations of future releases of AkWarm on your same computer will not require this lengthy process and will install quickly.
After installing the software, you should have an icon on your desktop to run the software or you can find the program in the "AkWarm" program group under the start menu.
