Unable to install Standard if Reader is installed

Hi,

I am trying to install Acrobat Standard on a user's machine that has a recent install of Acrobat Reader. When Standard installer is run it will try to uninstall Reader completely with the message that it is not compatible with an installed product (Reader).

If the Reader installer is run when Standard is installed it requires Standard to be uninstalled.

Looking at the extracted MSI files it seems that the Reader install files have AcroPro.msi, and not the usual AcroRead.msi. And when installed the Product ID and Reg keys are the same for both products.

Reader:

Standard:

Has someone in the Acrobat Reader product team updated with the wrong source files? Or am I missing something fundamental in how these products should work with each other? Maybe someone can help.

Thanks

Alex
