Here is my reply to the other forum thread with the same question:
I'm not sure why the RadControls for ASP.NET AJAX
detection of the VSExtensions
installer fails on your side.
There is a workaround to avoid the detection and install RadControls for ASP.NET AJAX VSExtensions
without having RadControls for ASP.NET AJAX
, but I would not recommend that. Just a small hint that came to my mind - did you run the RadControls for ASP.NET AJAX VSExtensions
installation as an Administrator
? The installer needs administrator privileges to access the local computer registry and detect if RadControls for ASP.NET AJAX
have been installed. Still, if you decide to try the detection-skipping
approach, you could follow the instructions I posted previously:
There is a small hack, which allows you to have the VSExtensions without running the official RadControls
installation. Please, keep it secret ;-). If you run the
Telerik.Web.UI_2009_1_311_VSExtensions.msi from the command line,
providing the SKIPRADCONTROLSSEARCH=true argument, you will get the
controls installed, i.e.
To uninstall the package you should use the same argument, i.e.
msiexec /x Telerik.Web.UI_2009_1_311_VSExtensions.msi SKIPRADCONTROLSSEARCH=true
Please note, this is just a hack for testing purposes. It installs the
accompanying files to the <SYSTEMROOT>\INSTALLDIRRADCONTROLS
folder. When using that, you also need to browse to the Telerik.Web.UI
assembly manually. There is no validation in the Project Configuration
Wizard, so missing to navigate to a proper Telerik.Web.UI assembly would result in an error.
I would recommend another approach though. As you probably already know, we released RadControls for ASP.NET AJAX Q1 SP2
yesterday. We shipped a new installer with the SP2 release, which
includes the VSExtensions in it. You can find the MSI download in your
Please give it a try and let me know if everything is fine now. Please note, you need to run the MSI as an administrator.
