I have encountered more problems with this new version. I have to preface this by saying that on the original install, I installed it over v4.5 and it had a glitch when doing so. It appeared to go smoothly until the end when I clicked on finish and got the pop up about the setup encountering an error and needing to close. The program ran fine after that except for the fact that there was no right click context scan option showing.
I decided to uninstall SAS and reinstall v5 from scratch. I tried to follow my usual procedure of using CCleaner to uninstall it. I clicked to run the uninstaller and nothing happened. I tried to run it again and it said the file could not be found. I looked in the Program Files folder of SAS and the only thing that had been removed was the uninstaller itself. Everything else was still there and the SAS program still functioned fully. I ran the installer again and got the uninstaller back. I then attempted to manually run the uninstaller from the Program Files folder and once again, it only removed itself. I then double clicked on the uninstall file with the DOS box icon and voila, SAS was removed. After the required reboot, I ran CCleaner's registry cleaner followed by Auslogics and Registry Mechanic to make sure all traces were gone. (there were quite a few things left over).
After another reboot, I then downloaded the latest version of SAS 5 and installed it. This time there was no error at the end but, I'm sorry to say, there still is no context menu option for a scan. I still only have options for Avast!, MBAM, and 7-zip. There also is no mention of an uninstaller in the Program Menu folder.
