AdobeAirInstaller
Windows 8.1
Do you want Adobe Air to install on your Hard Drive. Of course I say yes. It then goes to Install Set Up, I agree to the Terms and Conditions, It says installing, and in less than a second comes up with the message: Sorry an error has occurred, An error occurred while installing Adobe AIR. Installation may not be allowed by your administrator. Please contact your administrator.
Click Start, type services.msc in the start search box and press enter.
In the Services (Local) list, right-click Windows Installer, and then click Properties.
If the Startup type drop-down list is set to a value of Disable, select the Manual option from the Startup type drop-down list.
Click on Start button below the heading service status and click OK.
Then try to install again...
