I have a suspicion that you have something more than a ‘rights’ problem. However, let’s try 2 methods to get programs running. If the first one doesn’t work, try method two.

1. Right-click the program (or shortcut) you want to run and select ‘Run as administrator’.
2. Turn off UAC and try running the programs in the normal way. To turn off UAC, go to Control Panel > Classic View > User Accounts and click 'Turn User Account Control on/off'.

To prevent the security pop-up in the System Tray, right-click the red shield (or Control Panel > Classic View > Security Center) and click 'Change the way Security Center......' then choose 'Don't notify me and don't........'.

Post back here with your findings.
