Installing this package requires the following feature and its associated permissions: Apex Classes

I'm trying to install a MANAGED PACKAGE from my developer org to TRIAL Professional Edition, and it is resulting in following error:

Would this error still appear if开发者_如何学C I install the package in a purchased Professional Edition (not trial)?

As abeyer said you need to have your package put through the Security Review and it be Certified before you can install in Professional Edition Orgs.

There are 2 reasons for this:

• Only trusted Partners are certified to install in PE org. This makes sure that all packages listed on AppExchange with PE access do not contain any malicious code
• It avoids people using managed packages to circumvent the limitations of their edition.
