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 used Visual Studio 2010 to develop a web application. I formatted my machine and installed Visual Studio 2010 Professional. When I try to open old projects, I get an error saying:
The selected file is a solution file, but was created by a newer version of this application and cannot be opened.
I do not remember the version of visual studio 2010 I used the first time.
Can anyone tell me which version came after the professional edition?
Make sure VS2010 is updated to the latest service pack, otherwise check to see if the project was actually made in VS2012/13 in which case you will need to create a new VS2010 solution and rebuild it from your existing projects.
Open the .sln file in a text editor. In the beginning there is a marker which tells the VS version it is meant for. For VS 2010 it should look like that:
Microsoft Visual Studio Solution File, Format Version 11.00
# Visual Studio 2010
You should be able to change these values without any problems. As far as I know the file format did not change.
EDIT
Considering the comment of Dumisani: of course you need to target .net 4.0 and make sure no features of .net 4.5 are used!
Chances are you had a service pack installed that you are missing with a clean installation.
I edited my project (which was written in school using Visual Studio 2008) at home using Visual Studio 2010 Express. When I got back to school, I couldn't open my solution anymore as Visual Studio 2008 told me that the file was created with a newer version of Visual Studio. I asked my professor for help and he edited something in the assembly information of the solution and voila, I could open, run, edit it again as nothing ever happened.
However, I forgot what he did with the assembly information. Does anyone here know what he could have done? or is this approach not advisable?
At the top of the .sln file there would be a line:
Microsoft Visual Studio Solution File, Format Version 11.00
If you change the version to 10.00, it would correspond to Visual Studio 2008. Use any text editor for this.
The file format has not changed in between these versions (nor has it for Visual Studio 2012).
Edit the .sln file in Notepad and find the version number (11.0) on the first or second line. Change it to 10.0, save the file, and you should be good to go.
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.
I have created a project using Visual Studio 2008 and .NET Framework 2.0.
Now I want to open it in Visual Studio 2005 (.NET Framework 2.0).
When I try to open the solution in Visual Studio 2005 it is showing an error as "It is created using the Higher versions".
So is there any way I could open the project in Visual Studio 2005?
Or should I redo the entire project in Visual Studio 2005?
Please help me out!
Thanks in advance!
You can edit the solution file and project files (not recommended, but you can). If it's a csproj file, change the line
<ProductVersion>9.0.30729</ProductVersion>
to
<ProductVersion>8.0.50727</ProductVersion>
If it's the sln file, change:
Microsoft Visual Studio Solution File, Format Version 10.00
to
Microsoft Visual Studio Solution File, Format Version 9.00
Try opening the project file instead of the solution file. Otherwise just create a new VS2005 project and add all the files and folders from the VS2008 project.
You can use Visual Studio Project Converter, a handy tool to convert between most versions of Visual Studio (VS 2002, 2003, 2005 and 2008).
But unfortunately, converting .NET projects is not supported.
I have just encountered the same problem.
Modifying the .sln file and .csproj file by notepad is the solution.
If want to know more about the file format, we can create a simple project both in VS2005 and VS2008, then compare the project files.
