Problems during install/uninstall

[Telerik Admin]

Shortly after the Q2 2009 release we found that a lot of you experience difficulties with the uninstall of the RadControls for ASP.NET AJAX Visual Studio Extensions standalone installer and the subsequent installation of RadControls for ASP.NET AJAX Q2 2009. I'll try to summarize all the information we've collected in order to help fixing any problems of that kind.

We divide the installation issues in two:

• Problems uninstalling the standalone versions of the Visual Studio Extensions:
• The Visual Studio Extensions got installed only in the current user context. Hence, if one user on the same machine installed them, another user was not able to uninstall them. To solve the problem you could log in as the other user and uninstall the application;
• The first two releases of the Visual Studio Extensions performed a check for the RadControls existence during uninstall. Thus, if you uninstalled the RadControls for ASP.NET AJAX distribution prior to uninstalling the Visual Studio Extensions, you could do either of the following:
• install the RadControls for ASP.NET AJAX Q1 2009 distribution, then uninstall the Visual Studio Extensions and uninstall RadControls for ASP.NET AJAX Q1 2009 again
• force the uninstall. This approach involves using msiexec having the GUID of the installed Visual Studio Extensions package passed.
• For the Q1 2009 official release (VSExtensions 2009.1.311), run
  msiexec /x {7748C8E3-DE7C-454B-9903-9B420D99E1EE} SKIPRADCONTROLSSEARCH=true
• For the Q1 2009 SP1 release (VSExtensions 2009.1.402), run
  msiexec /x {B74F9F17-CC15-4E3D-A220-8478903AB85F} SKIPRADCONTROLSSEARCH=true

• Problems installing RadControls for ASP.NET AJAX Q2 2009 related to the Visual Studio Extensions standalone installer:
• The standalone Visual Studio Extensions installer leaves some registry entries on uninstall. Unfortunately, this happens sporadically and we were not able to find a fix for that. If the entry exists in the registry, it prevents RadControls for ASP.NET AJAX Q2 2009 from installing successfully. To fix that, follow the steps below:
• start the Registry Editor (Start -> Run -> Regedit)
• navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\ Telerik\RadControlsForASPNETAJAXVSX key and delete if found (the location is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ Telerik\RadControlsForASPNETAJAXVSX on 64-bit machines)
• start the RadControls for ASP.NET AJAX Q2 2009 again

Let us know if none of these suggestions helps and we will look into your specific problems.

Please excuse us for any inconvenience we might have caused.
