I accepted the update but it failed. It was late and a failed update to Adobe Reader was the least of my worries at the time.
Today, when I tried to use Adobe Reader, I noticed it had been uninstalled.
It’s not nice having to download and install something like Adobe Reader when I need to open a document, but the worst came when I tried to install it.
Adobe Reader requires elevated privileges to install but, due to the way the installer works, being a local administrator (I running Vista x64 Enterprise joined to a corporate domain) is not enough to install Adobe Reader on C:\Program Files (x86), because it was still failing.
Do you know what was the first name I thought of for this folder? C:\Program Files (Bad)
Just blame it on Vista.
