If i click Yes it shows error [Project Name] could not be compiled. Try rebuilding from source manually.
if I click No Nothing will happen…
Initially i did this project in unreal 4.9 and visual studio 13 now i am upgrading it to 4.12 and visual studio 15.

Hey armroyce-

If you’re using a source project, can you try opening the .sln and building the project in Visual Studio? If the compile isn’t successful, try right-clicking on the .uproject and select “Generate Visual Studio project files” and then build in Visual Studio again. If you are still getting compile errors, please post the errors that you’re getting for more information.

I tried all these methods… Now if i compile the project through the visual studio it shows the same error…
And when I am trying to open the .uproject file it shows the error like this…

If you are moving from 4.9 to 4.12, it may be useful to upgrade incrementally through the other engine versions. A number of source code and engine changes have been included since 4.9 and your project code may need to be updated to compile successfully. If you’re still unable to compile the project, please list the exact error you’re getting when compiling in Visual Studio?

I just copy all the project files into my new project file… It is working properly…
