  unable to uninstall - MVC Templates not visible

  Dec 13, 2007 06:14 PM|LINK

   I am running a 90 day trial version of Visual Studio 2008 Pro.  I installed the ASP.NET 3.5 Extensions CTP, but the MVC templates don't appear in File>New>Project.

  I attempted to uninstall the extensions (to try reinstalling them) and I get the following message:

   "A network error occurred while attempting to read from the file C:\WINDOWS\Installer\ASPNetExt.msi"
  

   

  Can someone help me?

  ASPNetExt.msi does not exist in the C:\WINDOWS\Installer\ directory.  Could this be due to the fact that I uninstalled the ADO.NET Entity Framework 1.0 (Pre-release Version) prior to attempting to uninstall the extensions?

  Either way, what do I do about it?

  Sorry to hear you've had some trouble with the project templates.You can run the following commands to get VS to reimport the templates (you need to do this from a Visual Studio Command Prompt: Start,Programs,Microsoft Visual Studio 2008, Visual Studio Tools, Visual Studio 2008 Command Prompt) 

  • <div mce_keep="true">devenv.exe /installvstemplates</div>
  • <div mce_keep="true">devenv.exe /setup
     </div>

  then launch VS again

   Thanks again for your help Chris.  For everyone else's benefit, here are the steps Chris and I went through (via email)...and the final solution:

  1. Ran the commands in Chris's post above.  They didn't work.
  

  2. Checked the C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ProjectTemplates\CSharp\Web\1033 directory to verify that I had:

      * MvcWebApplicationProjectTemplate.cs.zip

      * MvcWebApplicationTestProjectTemplate.cs.zip

     I did not.

  
   3. Re-downloaded the ASP.NET 3.5 Extensions CTP and attempted to run the ASPNetExt.exe.  Received the following error message:

  Unable to satisfy all prerequisites for ASP.NET 3.4 Extensions CTP. Setup
  cannot continue until all system components have been successfully
  installed.

  Details:
  
  Prerequisite check for system component ASP.NET 3.5 Extensions CTP failed
  with the following error message:
  "A previous installation of ASP.NET Extensions CTP has been detected.
  Please uninstall any previous installation of ASP.NET Extensions CTP and
  try again." 

   4. Finally, per Chris's direction:

  1. Launch the extensions setup, but leave it at the eula screen.
  2. You can then go to %temp% and in one of those subdirs there will be an
  aspnetext folder with the aspnetext.msi, copy that to the
  \windows\installer folder
  3. cancel the setup
  4. goto add/remove programs and uninstall the asp.net 3.5 extensions
  5. Once that's done, go ahead and re-run setup

   

  That worked.  MVC templates are visible at File>New Project... in VS 2008.

  Chris, thanks again for your patience and for walking me through all the steps to debug the problem.

  Hi,

   I have the same problems. I try to copy aspnetext.msi file to \windows\installer folder but I can not find \windows\installer folder in my business vista machine. I see \windows\downloaded installations\, \windows\downloaded program files\ and \windows\setup\ folders. Could anyone help? Thanks.

  Another thing you could try doing is running the following command from an elevated command prompt:

  msiexec -uninstall AspNetExt.msi

  Which of the above methods did you try? Are you unable to uninstall, or are you unable to see the mvc templates in Visual Studio 2008?
