When downloading updates for Spectrasonics instruments in Windows 7 through 11, make sure to use Windows Explorer to extract the zip file.  

Note: If you receive an error that reads "Files to be installed not found." while installing an update, please follow the steps in the article to resolve the issue. 

Third-Party tools like WinRAR, WinZip and 7-Zip might not properly extract the files (you may receive an error message saying something along the lines of, "An error occurred while trying to read the source file... [etc..]").

Right-Click on the zipped updater downloaded from the Update tab of your User account. Select "Open with" and choose "Windows Explorer":

Double-click the Application within, then select "Extract All":

Choose the path to extract the installer to (typically the Desktop) and make sure to check the "Show extracted files when complete" box:

When the extracted folder pops up, you can then run the application within the folder.
