SQROT users: 

If you are having issues upgrading to the latest version, please do the following:

1)  Close the SQROT program if it is open
2)  Uninstall SQROT (e.g., Windows Start Button | Control Panel | Programs | Uninstall a program)
3)  Goto https://www.ceder.net/csds2/
4)  Download and save sqrot2publish542.zip to a temporary folder such as c:\temp
    (downloading to the default 'downloads' folder may not allow you to unzip and/or run the setup program)
5)  Unzip the downloaded file sqrot2publish542.zip 
    (i.e., extract all files from the zip file to a temporary folder)
6)  Run the setup.exe file
    (if you get an message, then you probably didn't uninstall the program properly)
7)  Upon successful installation, SQROT 5.42 will run.
8)  You should not have to re-enter your user key, and the program may want to download a
    couple of files from the web.  You might also need to reset any shortcuts you have to the program.
9)  Delete the temporary files
10) To make sure you've got the very latest, run the SQROT program,
    and from the main menu, select 'File | Upgrade program from web'.
