Hi,

I was using the Acrobat Reader 9.4.2 on my Windows operating system. But yesterday a message pop upped for the update of the reader. I updated the files, but when I tried to install the files it failed. A message was displayed showing “Error code 1646”.

I tried numerous times looking for a solution online but could not find the answer. Tell me if you can help me with this. Thanks.

Try downloading the 9.4.2 patch manually from the link but do not download the MUI version. And then save the msp file on your desktop.

Launch the Command Prompt and then type the following command:

msiexec /p (space after p)

And then drag and drop the msp file on the command line window. It will list the entire path to msp file. Type /L*V "C:Readerpatch.log" /qb after the last quote and press the enter key. This will strike the patch installer off.
