Software update problem

I am trying to update to 15.5.14. When I launch the installation file (Manager.msi), I get an “Accessing the feature” dialog box asking me to point the way to Manager(2).msi. I have tried to change the name of the downloaded installation file to Manager(2).msi and browsed to that location where the downloaded file is located with no success. Another dialog box appears saying that the needed file cannot be found. I have done many updates successfully before without these dialog boxes showing up. Please advise. Thank you.

This happened to me too. I’ve upgraded to Win 10 and run several upgrades. After reverting back to Win-7 I can’t install Manager even after deleting all registry that I found.
Going back once again to Win-10 didn’t solved the problem:
