If you encountered no errors extracting SimpleViewer-Pro zip file, then it is unlikely that the svBuilder-Pro installation file is actually damaged or corrupt.
If the Installation Issues in the svBuilder-Pro User Guide do not help, then please try the following suggestions:
(1) Make sure that there is no trace of svBuilder-Pro on your system (perhaps from a failed install attempt) before trying to install the application again. If there is an entry in your Control Panel's 'Uninstall a program' list, please use it to uninstall whatever files exist. Otherwise, try manually deleting the following folders:
C:\Program Files (x86)\svBuilder-Pro
(2) Make sure that your version of Adobe AIR is up-to-date. The current version is v13.0 and can be downloaded from here.
(3) Make sure that you are logged in with an administrative account when you install and run both Adobe AIR and svBuilder-Pro.
(4) Try creating a new administrative user account and install svBuilder-Pro from there to see if this helps.
Hopefully one of the suggestions above will help.
