Unable to Install Downloads & Write Permission Question

[Thomas]

Can anyone help resolve this? I'm running Vista Ultimate on a 73GB SCSI
HardDrive w/ 50 GB still free. I downloaded MSFT's SteadyState 2.5 beta and
two other utilities. All three use Windows Installer. None offer the option
of installing as "Administrator". When I right click to "Install", I get the
message: "The Temp Folder is on a drive that is full or is inaccesible. Free
up space on the drive or verify that you have write permission on the Temp
Folder". Obviously the HD has plenty of space. How do I fix this or get
"write permission on the Temp folder" so I can get these utilities installed?

Many Thanks. I use MSFT's 1,527-page "Vista Resource Kit" book. On this
point it was confusing because whether UAC was disabled or not, I STILL got
(and still get) : "Internet Protected Mode: OFF" no matter what I do. This
still has me stymied.
