When running the installer for the NetAdvantage Silverlight Service Release (for Silverlight 4) I receive the following error message: Error 1721. There is a problem with this windows installer package. A program required for this install to complete could not be run.
The main profuce bundle (NetAdvantage for Web Client 2010 Vol. 1 Complete Bundle) installed fine.
I'm running Win7 Pro 64bit.
Any Ideas?
Hello,
As far I see form your details you got 1721 error caused by installer and OS settings.Here are few suggestions how to solve this.
1. Can you please try to disable the UAC In windows and try to install the products again. More details about the UAC you can find here:http://www.mydigitallife.info/2008/12/30/how-to-disable-and-turn-off-uac-in-windows-7/
2. Try to install the product as Administrator (as in, right click on the file and run it that way or run it from an Administrator command prompt) .
3. If this doesn’t help can you try to reinstall the Windows Installer.
I hope this helps.

Yes, turning off UAC did the trick. Thanks.
