1. Just put a password on your Admin account, that way you only have to use one account
2. Go to install bat and type in your username of the account and press enter
It will ask for the password, enter it and then enter it again to confirm (note that nothing happens when you type for the password, dont worry about it)
3. It willcomeup with a message twice and then you are done
I did this 2 nights ago and it is working fine now.
