Adobe Air will not install

Adobe Air attempted installation replies with and error message:

Sorry, and error has occurred while installing Adobe Air. Installation may not be allowed by your administrator. Please contact your administrator.

I have run as user and Administrator to no avail.

Most up to date version has been downloaded from Adobe.

Tried to delete any previous versions

No previous version of Adobe Air can be found on the computer.

I want to use an added program in Dreamweaver.

The add-on is XPOSE Gallery Image Manager

How can I install Adobe Air so I can use XPOSE Gallery Image Manager?
