Error 0x80131702 when installing .Net framework 2.0 Redist

  • Article

The other day I encounter a problem when installing .Net framework 2.0 redist. It is a fresh install on a clean Windows XPSP2 machine.

During the install, setup pops up a dialog says LoadLibraryShim failed to locate fusion.dll, hr=0x80131702.

From CorError.h (in you .Net framework SDK include directory):

#define CLR_E_SHIM_INSTALLROOT EMAKEHR(0x1702) // Install root is not defined

The error means mscoree cannot find where the installroot is.

InstallRoot is a registry value of type REG_SZ in HKLM\Software\Microsoft\.NetFramework. It usually points to "%windir%\Microsoft.Net\Framework" in x86 and "%windir%\Microsoft.Net\Framework64" in x64/ia64 (replace %windir% with your real Windows directory.)

After I added the InstallRoot registry, the setup can be resumed and finished successfully.

    OK it's nice to know the solution, but the obvious question is why the error happened to begin with? Why wasn't the InstallRoot entry written by the setup program? I shouldn't have to tell dotnetfx how to do its job.

    Out of the many times of installing NetFx, I only encountered this problem once.

    I don't exactly know why the registry is not written correctly, but it certainly depends on the environment.
