Thanks for the question. Sometimes you may occasionally visit a webpage that requires a plug-in that’s not already on your computer. Here are some tips for getting the correct plug-in.
Check the webpage for a recommendation
Websites often recommend the appropriate plug-in. If the website doesn’t recommend one, contact the owner of the website.
Use plug-ins designed for an Intel processor
Your computer has an Intel processor and can use the Intel version or Universal version of a plug-in. Your computer can’t use a plug-in designed only for PowerPC (PPC) processors.
