ess64 drivers?

Hi,

I had 2 computers, both with vista ultimate sp1 64bit installed. I downloaded and installed ess4 on both. On one machine, near the end of the installation it compiled, and installed some sort of drivers. But on the other machine it never asked to install any driver during the installation. When it installed the drivers on the 1st machine windows vista popped up a message and ask me for permission to let ess64 to install, and on the 2nd machine windows vista did not ask for permission. I'm wondering what was this driver that it installed on the first machine but not on the 2nd machine.

 

Hello kairii,

Is UAC enabled on both machines?

Thank you,
Richard
