Delphi 2007 – when you lost your Borland.*.Targets file during a Windows upgrade

Posted by jpluimers on 2018/08/09

When upgrading Windows, it will create a fully new %windir% for you.

Any files an application installed files in them will be gone, and appear in a %HomeDrive%\Windows.old

If you’ve deleted that directory because you thought all your applications worked, or the Windows 10 upgrade automagically deleted the Windows.old directory by itself after some grace period, then you might be in trouble.

One of those applications is Delphi 2007. I wrote about a different issue on x64 Windows on that product before: Delphi on Windows x64: solution when project compiles fine under IDE, but not using MSBuild.

Basically it puts these files in %windir%\Microsoft.NET\Framework\v2.0.50727:

  • Borland.Common.Targets
  • Borland.Cpp.Targets
  • Borland.Delphi.Targets
  • Borland.Group.Targets

Those will be gone if you deleted the Windows.old directory.

If you are lucky, the files are also in this directory to copy back to %windir%\Microsoft.NET\Framework\v2.0.50727 and %windir%\Microsoft.NET\Framework64\v2.0.50727:


And if you’re not, you can find them here too:
