[Tex/LaTex] problem with Beamer in the latest MiKTeX update

beamermiktex

This is about MiKTeX Revision 2.9.6360.

Immediately after the latest MiKTeX update, my Beamer files stopped compiling. When i tried to compile a file that had been working fine I got a Package installation popup saying:

tex\latex\beamer\beamerbasemodes.sty

Is missing.  It is part of the following package

beamer

So i clicked to have it installed. All that achieved is that i got an error message

! LaTeX error: File 'beamerbasemodes.sty' not found

I repeated this a few times with minor changes to the file, and then went to the MiKTeX Package Manager to see what parts of Beamer are installed. It said none were.

Either the update had removed Beamer, or the attempt to install beamerbasemodes on the fly had done it. So I reinstalled it by hand. In fact i did this several times in various ways. It made one difference. Sometimes the problem package was identified as

translator.sty

In case it would help, I ran Update FNDB and restarted my machine. Each time I installed Beamer, the Package Manager then reported that Beamer was installed.

But when I tried to compile the file, the same things happened all over. And when i went back to the MiKTeX Package Manager it reported Beamer is not installed.

Is Beamer now out of date? Or is this a problem on the new update? Is there a simple fix i can use?

The problem disappeared when I used the MiKTeX Package Manager to install Beamer and translator, used Refresh FNDB, and restarted my machine.

Experience with a second machine shows the latest update indeed replaces the old Beamer with one that does not have translator in it, so I had to install translator separately using the MiKTeX Package Manager. When I did that immediately then the new Beamer stayed installed and there was no need to Refresh FNDB or restart the machine.

But for some reason when I tried to let MiKTeX install translator on the fly it not only failed, but erased my Beamer.
