I recently heard from a customer who tried to install Visual Studio 2005 SP1, but the installation was blocked with a message stating that the Visual Studio 2005 Web Application Project add-in needed to be uninstalled first. However, the system did not have any items with that name in the Add/Remove Programs list.
Microsoft released a new set of web application projects for Visual Studio 2005 after the final release of Visual Studio 2005, and they are now included as a part of VS 2005 SP1. Because they are included in SP1, the standalone version must be uninstalled before installing SP1. The tricky thing here is that there are 2 programs that have to be removed to fully uninstall the web application project add-in from Visual Studio 2005 to allow installing SP1 - the MSI-based add-in, and a Visual Studio 2005 hotfix to support web application projects.
If you have the Visual Studio 2005 Web Application Project add-in installed and want to be able to install Visual Studio 2005 SP1, you can use the following steps to uninstall both of the programs that must be uninstalled:
After uninstalling both of the above packages, you should no longer receive a blocking dialog related to the Web Application Project add-in when trying to install VS 2005 SP1.
Everytime we try to remove the web application I get a "fatal Error During Installation" We have tried to uninstall all the VS 2005 stuff. Still can't get it to uninstall.
Hi JamesNoe - Can you please try the steps listed at http://blogs.msdn.com/astebner/archive/2005/10/30/487096.aspx and see if they help resolve this issue?
After doing Aaron's steps, 2005 Web Applications is removed, but SP1 still thinks it's installed. Remove:
C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\ProjectTemplates\CSharp\Web\WebApplication.zip
Finally, SP1 installs!
