I didn't see this issue in the forum, so:
My XP Pro SP3 install has taken over my context menu -- it placed "Read" at the top of my context menu for several different file types, including .exe, and it now attempts to open said files, which of course results in a "not a supported file type" prompt.
It even tries (and fails) to re-open itself when I click its desktop icon!
I can still open affected files by right-clicking in Windows Explorer (or shortcuts) then via context menu Open, but I have lost the ability to open programs via start/programs menu, desktop and directly in Windows Explorer (dbl-click).
There's no exe extension for me to re-associate in the Windows Explorer Tools>Folder>Options>File Types. I've looked in HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers and there's no Adobe entry.
I've uninstalled everything Adobe, wiped all relevant files (found via Search), cleaned the registry, reinstalled from scratch. No joy.
Can I correct this (i.e., get rid of "Read" in context menu) or must I do w/o the latest Reader?
I'll take the utter lack of response to mean there is no fix for this. So be it. Since I can't even boot up the affected machine because of this issue, I'm ditching Adobe Reader and using Foxit instead!
