Error: The project type is not supported by this installation

[Guest]

Hi,
I had created a solution on a different machine consisting of 4 different
projects for each of the different layers Business, Data, Schema,
Presentation where it was working fine. I copied (folder copy) the same
solution on my machine. The Presentation Layer project is the start up
project but my Solution is unable to Load this Project and gives me an error
Message :"The project type is not supported by this installation" (it gives
this message for the .csproj file). The error is misleading because the
solution loads all the other projects i.e Schema, Data, Business with .csproj
files.
I have already tried running devenv /setup but it was not useful.

Any idea on how I can get this running??

Thanks

Did you create your own solution, then copy the other stuff over and try
to
open your solution as if they were part of it? Am I understanding that?

Try creating a new solution, be sure to pick the right solution type
(Windows Application, etc.), then do AddExistingItem, and go find the
files you want to add. On my system, when I do this, it copies them from
where they are and puts them in my current solution's directory.

Or go back and copy all of the folders, including the top one, from the
original machine.

Try launching VS on both machines and checking whether the splash
screens list all of the same products. Then go through the new project
wizards on both and see if there are any differences. Then check the
Add-In Manager and see if there are different Add-Ins installed.

It sounds like one VS has more installed than the other, from the
description of the error message. If you can find differences (even if
you're not sure what caused them) and post them here, we might be able
to suggest a resolution.

Thank you for your response Robin,
If I try to create a new website and a solution from scratch ,I face a
different problem now. My presentation Layer has all the .aspx files. Hence I
would like to have the Presentation Project as the startup project and have
one of the pages in the Presentation layer to be as a start up page. If I
create a new WEBSITE, It doesnt give me the option of setting the index.aspx
in Presentation layer as the Startup page. Also, even if I set up the
Presentation layer as the start up project, when I debug it I keep getting
the error: Project of output type class library can't be started directly.

Thank you for your help

Thank you for your response Damien. I had created VS2005 in another machine
and copied the whole folder to my new machine. I do not have access to the
other machine now but what I can tell is that the new machine has everything
installed. The error seems to be misleading to me.

thanks
Manika

It was unclear to me that you were working on a web application.
In that case, I don't know what to tell you to help you. Maybe if you
posted your problem to microsoft.public.dotnet.framework.aspnet
one of the ASP gurus could help you.

Having had this very problem on Friday, I am inclined to think the project
with the aspx files is a web application project created on a PC with
support for that in visual studio. The machine you're trying to open this
project from does not have web application project support installed.
