Problem installing acrobat reader update on Windows

[brucef16847509]

have a problem installing acrobat reader update

error code 1321, does not have enough privileges to modify the file C:/programfiles(x86)\comonfiles\adobe\acrobat\activex\acropdf.dll

I need the application to be up to date and need a quick resolution on the same.

Reply as soon as possible on this
