How to install acrobat when you open the office

After acrobat 8.12 is installed in 64-bit win7 recently, every time the Office software is turned on, a prompt will be prompted to install acrobat, And the last prompt will appear "cannot find ...... /amd64/adobepdf. DLL file error"

In fact, under the Adobe \ acrobat 8.0 \ acrobat installation directory of Acrobat, there is an adobepdfl. dll file which can be copied to the amd64 folder and renamed to adobepdf. dll.

Open the office software again and prompt that the installation will be successful once and for all.
