After having installed all the RC1 parts, including "Orcas" and try to create a new project in VisualStudio 2005 (Windows Application, XAML Browser Application or Custom Control Library) I get an error message:

"The project file '.....' cannot be opened.

The project type is not supported by this installation."

I've tried reinstalling everything but it's still giving the same error message.

Could it be because I'm running a swedish version of Windows XP? Although I haven't had this problem with other releases.

You could also try to run the following command:

devenv /ResetSkipPkgs

This will try to load any Visual Studio packages that failed previously at some point, such as the WPF project flavor package, which would cause the error message you're seeing.

Well, I answered my own question...but hopefully I can help someone else.

I reinstalled VS.NET 2005 C# Express again and this time it works. I guess the problem was that I installed Orcas after I had reinstalled the IDE. It would appear that it has to be installed after everything else.

Got the same problem.. Updated to RC1 and now I can't work.. Pleeeaaase resolve this for usMicrosoft!

"The project type is not supported by this installation"

When opening the old WinFX projects or trying to create a new project, all the same.

I found something that solved the problem for me anyway, in the Web page opened at the end of the installation of "Orcas". Under "Setup issues":

Open the run-dialog (start-->Run) type "devenv /setup" and press ok.

Opening an old project or creating a new project, works for me now. Hope it does it for you guys too.

Good luck!

Hello we would like to investigate this issue to understand what might cause you to see this error message. Can you please help elaborate more on your installation steps.

Did you install Development Tools and its prerequisites from the from the following locations?
.NET Framework 3.0 RC1
http://www.microsoft.com/downloads/details.aspx?FamilyId=19E21845-F5E3-4387-95FF-66788825C1AF&displaylang=en
Windows SDK (Optional if you want integrated help)
http://www.microsoft.com/downloads/details.aspx?FamilyId=117ECFD3-98AD-4D67-87D2-E95A8407FA86&displaylang=en
Development Tools for .NET Framework 3.0 RC1
http://www.microsoft.com/downloads/details.aspx?FamilyId=935AABF9-D1D0-4FC9-B443-877D8EA6EAB8&displaylang=en

Can you reproduce this issue on a clean machine (one that has had no prior installs of the development tools or .NET framework 3.0) or has this machine had previous versions of either the .NET Framework 3.0 or development tools installed?

If this is not a clean machine what prior working versions of the .NET Framework 3.0 & Development Tools did you have before uninstalling them and then installing the RC1?

Did you ever use this command to install the Development Tools on your machine, "msiexec /i vsextwfx.msi WRC_INSTALLED_OVERRIDE=1"?

What operating system version and os language are you using?

Thank you

Anthony

Thanks Marco. This seemed to do the trick. I'm now able to both create new projects and also open other WPF projects. Thanks again.

Anthony,

Trying to answer your questions...

Yes, it was downloaded from the locations you listed.

Unfortunatly I don't have a clean machine to try on, both my development machines have had several CTPs installed. And I only had this problem on one of the machines, the only difference between the machines are that on the corrupted one, the operating system is swedish and I also forced an install of the June CTP of Orcas ontop of the July CTP of .Net Framework 3.0 using the WRC_INSTALLED_OVERRIDE trick.

Hmmm...this didn't do the trick for me.

I was previously running June CTP (with sdk, orcas, etc). I followed all uninstall instructions beforehand, and installed (in this order)

1. RC1 framework
2. SDK
3. uninstalled/reinstalled VS.NET 2005 C# Express
4. Orcas

at the same locations listed in the post above.

I did have the flavor error after step #3 (in addition this error), but installing Orcas took care of that one. I also tried both commands listed in this thread, neither of which seemed to help.

I should note that I do have VS.NET 2003 installed too, and when I run devenv /ResetSkipPkgs it opens 2003, not 2005 express.

Any suggestions?

[EDIT: I can run XAMLPad and open & run projects in VS.NET 2005 C# Express that I didn't create (such as from the SDK samples).]

Well, I answered my own question...but hopefully I can help someone else.

I reinstalled VS.NET 2005 C# Express again and this time it works. I guess the problem was that I installed Orcas after I had reinstalled the IDE. It would appear that it has to be installed after everything else.

That's correct you have to install it after everything else

I have created my own package with custom project type for custom language. I have also created the installer for my package and when I try to install it on "clear" virtual PCI have got the same error message:

"The project file 'THAT STRANGE BUT THERE IS A PATH TO THE PROJECT IN THE TEMP FOLDER OF MY USER PROFILE' cannot be opened. The project type is not supported by this installation."

There are two weird things:

1. The fact the error occurs :)

2. Path to the project in errror message. I set the path 'C:\Projects' in New Project dialog.

The testing machineworksunder Virtual PC. Environment is very "clear". It is a WinXP Pro SP2 withVisual Studio 2005 Team Suite installed. And the second application I installed was my package.

Well, as you can see neither Orcas nor anything else can influence this error.

Please help me. Any ideas are welcome!

Thanks!

Hiya

To help with the investigation - I am running VS 2005 Team System for SD on XP Pro SP2 English with all latest updates. I downloaded and installed all the RC1 files as this is the only version with a GoLive licence. The rest of WinFX works fine its just WPF that doesn't work for me with the project type not supported error.

The wierd thing though is that if another user logged onto my machine the WPF stuff works fine. We even ghosted another working machine and it still doesn't work for me. This problem therefore must be caused by a setting siomewhere and isn't actually an installation problem.

For me the problem was solved by running devenv /setup

Thanks - this solved my problem when upgrading my older version of 'orcas' to the December 'January' CTP.

Cheers, Jonathan

Install Microsoft® Visual Studio® 2005 Team Suite Service Pack 1
