I am running a freshly installed MiKTeX set-up (v2.9, x64) but it fails to install updates through the "Update" tool. After selecting packages to update, it downloads them but then interrupts the process with this error: the MiKTeX package management utility could not be found.

And when trying to open the Update tool from the "Package Manager" I immediately get this error: The update helper could not be found.

After some googling (see links below) I have come to believe that both problems are caused by the fact mpm.exe seems to be missing on my system.

Could anyone perhaps provide me with that missing exe? Preferably the x64 version.

Edit Possibly related bug reports I found:

  • Opening the update manager from the package manager never really worked. Did you check with the package manager (admin) if there are new (miktex) packages (after doing repositories->synchronize) and did you install them?

It turned out the problem was indeed caused by the missing mpm.exe.

The reason is that somehow the (current) "Basic" MikTeX installer does not install the miktex-mpmcli-bin package. This really should be considered a bug because mpm.exe is essential for the correct working of a number of MikTeX (GUI) tools which said installer does install (e.g. the "Update" tool).

To resolve the problem it suffices to install the miktex-mpmcli-bin package through the "Package Manager".

  • Strange. I also installed Basic MiKTeX (some years ago) and had no this problem.
