Acroread32.exe deleted

Hello nice people,

in my company, we use Adobe Reader a lot (about 800 computers), in the latest update of reader we are experiencing a problem, the software updates automatically, but then the users cannot open any pdf's and the file "acroread32.exe" vanishes from the folders of the software. I tried to repair the instalattion, but it did not work.

I have to uninstall the new version, and reinstall an older version. Then, the software works again.

Any help available? We have 800 computers, all updating automatically the adobe reader software...

Thanks,
