I've tried using Adobe's program where you send them your email and requirements and they email you a link to download, but even if you explicitly specify Reader 8 (they give you 8 or 9 to choose from), the email you always points to the distributable install of Reader 9.
I've already taken a hit after installing on Sr VPs who later complained they could not open documents (trust me, updating them first was not my decision). Soon after we discovered the problem was because it was instaleld from a UNC location (\\server\share\folder as opposed to R:\folderinmappedshare\installfolder\). While this can be rectified by reinstalling from a mapped drive, I'd rather wait until 9.1 comes out before giving the new version another shot. However, I WOULD like to deploy updates to version 8.1.3 in our domain. Is there a way I can do this other than running Reader and clicking on Help, Check for updates? That means one internet download for each PC and that ads up.
