how can I replace this component without reinstalling all my programs?
Probably not and, contrary to kglad's proposal, simply downloading the file and placing it in the folder might n ot resolve the issue at all. In fact I tend to think the file is already there. Something is simply blocking it or it never loads because your system isn't compatible, but you did not provide any system info or tell us what version of Acrobat you are using even, so nobody can tell anything beyond that....
