On some Sketch when loading, VS complans that NET Framework 4 is not installed, but is!

How come?
How resolve?

/Bertil

how did you get on with this?

please make the problem and email your project in a zip. we can see in the .vcproj file what it is trying to do.

Things you should do...

Close visual studio, open task manager and kill all devenv.exe processes.

Then re-start visual studio to see if problem is resolved.

If the problem is not resolved or if there were not any devenv.exe process then please re-apply Visual Studio SP1

Does this fix the problem?

Thanks for the files. I think we are looking for the problem in the wrong place, the files you sent are good and normal.

This is definately a problem with your visual studio or .net installation so we need to  make a few tests to narrow the problem.

The first thing to do now is to create a new empty C++ win32 project using the normal Visual Studio "File>New Project" and to add a single .cpp file to it. 

By making this test you are using normal Visual Studio commands and not the Arduino addin menus.

Can you do this without an error?

Thanks

Interesting, my next suggestion was to try compile. I think the .net 4 error appears when visual micro attempts to alter the c++ project settings.

We can see from your test without visual micro that Visual Studio is not happy with the C++ install

I will try to search microsoft for the error later today to see what is recommended. Maybe you can do the same. Why is visual studio 2010 looking for 2008 when you compile a C++ project?

This seems to indicate that the C++ of your vs 2010 is wrong. For it to ask for 2008 it suggests an older version of C++ is installed. This would also explain why vs 2010 says .NET4 is not installed.

Can you explain the history of your visual studio uinstall? how lon has it been installed? was it originally vs 2008?

So you are saying that Visual Studio and the Arduino plugin worked correctly until you altered the default programs path?

In this case I think the suggestion to alter the program path does not work correctly for Visual Studio

So maybe it can be fixed by running the Visual Studio Installer and clicking "Repair"?

Bertil here again.
"Repair" chaged nohting.
this is the error-log:

the setup-log is large, I have it, tell my if You need it.

/Bertil 

Yes, the problem is obviously not Visual Micro, 
I have got same hints.
Have to fix Visual Studio 2010 first!
I let you know when/if I am up and running again:

Well done! I will add a page to the main site for this just in case some one does the same 

Thanks for the update
