do that i think i found a solution. i'm going to download tweakuac.exe on my other computer and send it to myself through email. hopefully, on my vista it will open and work to disable uac from my limited account. I'll try to remember to update you on the news. Thanks! I am working on a Dell laptop that has Windows Vista Home Premium. I am trying to install a program that is downloaded from one of our hospital vendors to view xrans online. Whenever we attempt to download and install the software we receive an error stating that there isn't enough disk space. I've seen this before in Windows XP Prof and it was related to Admin rights. There's only one user account on the laptop and he has Admin rights, but it still fails to install the program correctly. How can I get around this? I've made all sorts of UAC changes and nothing seems to work. Help! Have you tried Safe Mode yet? If not and you are unsure on how to get there: Turn on your computer and continuously tap the F8 key. Advanced option menu will appear, go to Safe Mode using the direction keys and click enter. After it is done loading there will be a login screen similar to the same screen that you see when you login normally. Click Administrator. If there is no Administrator click your account. A screen will appear asking about system restore. Unless you want to restore click
