Hello Lou,
Adobe Reader 9 will tell you, in Edit-Preferences-General-Applicatino Startup a value for "Currently in Certified Mode:" reflecting the current mode. If no 3rd party plug-ins are installed, even if the check box right next to it "Use only certified plug-ins" is not checked, it will show that it is in certified mode.
To have PP Search 7 in Acrobat 9, make sure you HAD Acrobat 9 installed at the time you installed PlanetPress Suite 7. If not then it will not appear.
I would suggest you simply uninstall PP Suite 7, double check Acrobat 9 is indeed installed and has been started at least one time, then re-install PP Suite 7.
In Acrobat, before or after installing PP Suite, make sure the "User only certified plug-ins" option is UNchecked in Edit-Preferences-General-Applicatino Startup
Let us know if that solves your issue.
Best regards,
