Having issues with a 3rd party plugin we've used for years...there is presently no 64bit version. we use it with the win32 version of reader. Since the Jan 10 update, we get "Invalid plugin detected. Acrobat reader will close". What happened with the Jan 10 update in the win32 version of Reader that could cause a previously working plugin to stop working? I read that the experimental 64 bit version does not have plugin support; but not reading anything about the 32 bit version having any changes or issues that could impact 3rd party plugins.
