Install Canvas app managed package to Professional and Group edition

Question

I developed a canvas app that display a custom section in the account's page, so that I uses:

• canvas app
• virtualforce page
• page layout
• profiles (to assign which users can see the application)

I installed the app on the Enterprise edition as a managed package and it worked as expected, the problem is when I tried to install it on other editions I faced the following problems:

• in the Group edition the installation failed and it gives me a meaning less error message but mostly it can be installed because it includes component which is not supported.
• in the professional edition every thing works as expected but when it render the app it gives a permission error, and when I tried to allow the users throw profiles, I can't find a profiles link.

so my questions is:

1. Can I install a managed package which include a canvas app into a Group Edition?
2. How can I manage the permissions to make the application works in the Professional Edition? can I include this permissions in the package? can I just allow all user form the beginning?

thanks

Group and Professional have limitations:

Your app can contain business logic such as classes, triggers, email services, etc. written in Apex. As a general rule, Apex is not supported in GE/PE, so it will not run in these editions. However, Apex developed as part of an ISV app and included in a managed package can run in GE/PE, even though those editions do not support Apex by default.

Also, from Canvas documentation:

Group and Professional editions can only create apps with OAuth Access method unless profiles, page layouts, and the API have been enabled.
