It looks like windows has tried to solve a problem by trying to install in compatibility mode. On the install setup icon right click and look at properties. Now select compatibility mode. If XP is ticked go to the bottom and select change for all users, un-tick XP and tick install as administrator.

When yo go to install right click on Icon and select run as administrator. Some times you need to re-boot and then do this.

I suggest that before you install ACT !, completely disable UAC. (User Account Control)

Additionally, while installing Act! and activate with the license, temporarily disable the firewall and antivirus.

The user that installs and activates Act! must be the local administrator type.

best regards and good luck...
