21. Do I have to be logged in as administrator ?

In order to use the TCP Optimizer to its full potential, you should be logged in with administrative privileges (user in the administrators group), so you have permissions to write to all the related Registry keys.

Windows 7/Vista/2008 add some more security measures, so you will have to take some additional steps to run the program as administrator, as follows:

1. Save the TCP Optimizer to your dekstop.
2. Right-click -> Properties -> Copmatibility -> check "Run this program as an administrator" under priviledge level.
3. Click "OK"

Now the program should start with administrator priviledges when ran.
