Is there a way to regenerate a missing .resx file?

I have the source for a project, but am missing the .resx file, which prevents compilation. Is there a way to re-generate a resx file for it? This is a C# project I created with Visual Studio 2010 Professional on an XP machine that I'm trying to open with Visual Studio 2012 Ultimate on a Windows 8 machine.

UPDATE

It (Resources.resx) was actually there (under Properties), so I guess "cannot be found" means: "I don't like the one you gave me."

When I mashed F6 to give it another try, I got the warning, "A custom tool 'ResXFileCodeGenerator' is associated with file 'Properties\Resources.resx', but the output of the custom tool was not found in the project. You may try re-running the custom tool by right-clicking on the file in the Solution Explorer and choosing Run Custom Tool."

also: "A custom tool 'SettingsSingleFileGenerator' is associated with file 'Properties\Settings.settings', but the output of the custom tool was not found in the project. You may try re-running the custom tool by right-clicking on the file in the Solution Explorer and choosing Run Custom Tool."

I ran "Run Custom Tool" for both Resources.resx and Settings.settings, and still get the same error and two warnings.

If you have compiled the project in the past and have the dll/exe available, you can use JetBrains' DotPeek app to export the resx XML from the assembly

Open the dll/exe in DotPeek

Then double-click each resource to see the XML in a window. You can then copy/paste the XML into a text editor and save as a .resx file.

Don't bother right-clicking the resource and trying the 'Save Resource to File' option, as this doesn't create the file in the same format as you see on the screen.
