I have a visual studio 2005 solution with many projects. Yesterday I was able to open it normally. Today, when I double click on it, I get the following error message:
The selected file is a Visual Studio solution file, but was created by a newer version of Visual Studio and can not be opened.
Please help.
Sounds like you, or someone, opened the file in VS 2008/2010. The solution file has been upgraded. You can create a new solution, add the projects, of course in 2005.
I right clicked on sln file and used Visual studio version selector to open the file and it was successful.

I'm looking for a way to update my visual studio 6.0 .sln file to a newer IDE like Visual Studio 2019. When I attempt to open it, it gives me the option of a one way upgrade, but I get errors such as:
"Unable to convert project. Please make sure this is a valid Visual C++ 6.0 project." on a .dsp file.
Is there a proper way to do this or do I need to re-install Visual Studio 2006 just to open this project? Thank you!
Funny question but I stacked on it. I opened in VS2013 solution file which uses VS2012, but it still doesn't show me any screen for upgrade solution to VS2013. I mean I can open this project in VS 2013 and it works but solution file still shows that it use VS2012
According to this article some wizard should be shown, but it doesn't

Found the answer. We need to correct manually the Visual Studio sln file like this
Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio 2013
VisualStudioVersion = 12.0.21005.1
MinimumVisualStudioVersion = 10.0.40219.1
Open the project using VS2013, then go the the directory that the project is in and change the
extension of the Solution file (*.sln) to something like *.sln_12. Now save the project and a new sln file will be created.
Check this url http://visualstudiomagazine.com/articles/2013/06/12/vs-2013-can-load-vs-2012-and-vs-2010-projects.aspx. It supports round-tripping with older versions of visual studio so it doesn't upgrade solution/project file automatically.
I recently installed the Windows Phone 7 SDK that came bundled with Visual Studio 2010 Express for Windows Phone. I downloaded a sample app and tried to open the solution file. When I checked the solution view window, the app project was not loaded. Every time I tried to reload the project, it flash as available for a moment and then go back to being unavailable. I tried all the usual tricks like removing source control from the .csproj and deleting the .user and .suo files. Any ideas?
Ok I figured it out. When I open the solution file, it opens in Visual Studio 2010 Shell. What I needed to do was to go to Visual Studio 2010 for Windows Phone, open existing project, and then browse to the solution file and open it. Sorry for the confusion everyone!
When I open my SLN file in Visual Studio, it launches and loads correctly with no errors. When I select a VB file from the Solution Explorer, I get the following message:
I have tried to associate the file type with Windows, but it is already associated. What can I do to get my files to open? HELP PLEASE!
EDIT
: I can right click and open any file in Visual Basic Express and it works, but the problem is that when I am in the IDE I cannot open files from the solution explorer which means I cannot edit the UI.
The problem described was occurring due to a bug in the Windows 8 developer preview. Upgrading to the Consumer Edition fixes the problem, and adds a number of stability improvements, plus a new Visual Studio IDE is available: Visual Studio 11.
I am trying to open a solution file in source safe 6.0d in Visual Studio 2005 (no service packs installed) and I get the Conversion Wizard saying it was created in a previous version.
So I try to open it up in 2003 sp1 and it says it was created with a newer version of visual studio?
Is there a way to tell what version of Visual Studio is in Source Safe?
Any ideas?
Look in the .sln file. Starting with VS2005, the second line has an identifying tag, such as '# Visual Studio 2005'
Each project file also has a 'ProductVersion' attribute. My guess would be that some projects within the solution have already been converted to a newer version.
