I have Windows 8 and this is the message I get when it try to open Adobe PDF. Also says
PDapp.exe.bad imageadobe/OOBE/PDapp/P6adobe_oobelib.dll, bit designed to run in Windows or has error.
Reinstall the program and make sure your files are not blocked. "Bad image" errors mean that the DLL cannot be loaded to the correct memory addresses and that most commonly happens when some security tool is blocking stuff...
If you are installing a version prior to AA X, that may also be a problem. Assuming it is AA X is at least what you have, you should also log in as the administrator and disable anti-virus during the install. After doing the install, open Acrobat and go to Help>Updates to install updates.
