Hi Sandy55,
Just to clarify about System Restore - it reverts system files, installed applications, Windows Registry, and system settings to the state they were in at a previous point in time (a restore point).
This means that System Restore isn't choosing to use a different version of Secure Browser per se, it's just using the version that was installed at the time when the restore point was created. If you use System Restore to solve the error you are getting, you can (and should) then download the latest version Secure Browser and update it afterwards.
