I currently use A1, Regvac, Winrescue:
To update I go to the website and click download for each program and then check the current version. Is there a better way?

   At the bottom of each product page and in the Registered Users section, there is a link to the current version information.  You should compare that with the version information in the product.  There is not a better way.

Thanks for your prompt response. I consider the question answered.

   The latest versions of RegVac and A1Click now have update links in them.  It is under the Help menu of RegVac and under the Order menu of A1Click.  It says, Check for Updates.  When you click on Check for Updates, it will check with our website and see if there is a more recent version.  If so, it will take you to the Registered Users section to download the latest version.
   You will need to close the program before you install the newer version.
