I work with Windows 7 on this machine. But this Windows 7 is protected and I cannot run .exe files on this machine.
How can I make the executables run on this computer?
Note: My account doesn't have Administrator rights.
If you're not an administrator, ask your administrator for permission to run them. There is most likely a good reason as to why you do not have the ability to run them.
If this is actually your machine and you have forgotten the administrator password or similar, please give more information.
