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
:
C:\ProgramData\{B59CE2E6-B15A-4F23-BD0E-72BF2ADDC3C7}\core\7EFD2DA3\6C948720
And if you’re not, you can find them here too: https://gist.github.com/anonymous/ab801cd925e5e634518fd5592eb2a46e
