Milko,

     I was able to successfully install after I made the following changes on the Windows 7 machine that I have been using. 

— I added a registry key to allow msi file to be run as Administrator (https://www.howtogeek.com/178826/how-to-force-an-msi-package-to-install-using-administrator-mode/).

— Overcame the following error: Infragistics Error – "Could Not Access Network Location %SystemDrive%\inetpub\wwwroot\" by following the instructions at this URL (http://ayanigamage.blogspot.com/2011/04/infragistics-error-could-not-access.html).

     So all seems to be working!  Thank you for your great support!

     As an update, I was able to log onto the Infragistics site and access my account.  My account has the product keys and the ability to download the software.  I was able to download NetAdvantage for Windows Forms 2006 Vol.3 [.NET 2.0].  When I attempted the install from the newly downloaded file and associated product key, I received the invalid CD-Key message again.

Alan,

     I did restart the computer and received the same error message, which I noticed is not visible–I pasted in a screenshot.  The error message is just telling me that I have entered an invalid CD-Key.  The msg says "The Infragistics NetAdvantage for .NET 2006 Vol. 3 CLS 2.0 CD-Key you have entered is not valid." 

     I have "NetAdvantage for .NET 2006 Vol 3 Corporate" installation msi.  Do I have the correct version that contains “Windows Forms 2006 volume 3” or I still need to request a Back key from sales?

thank you for your help…

Under my Infragistics account, I have the following licenses (see below).  I tried to install NetAdvantage_20063_CLR2x_NET.msi using the highlighted key, but I this error.  Do I have the correct version that contains “Windows Forms 2006 volume 3” or I still need to request a Back key from sales?
