I've tried numerous times to install many effects in After Effects, but none of them seem to work. I've put the file in the plug-ins sections, but they will never appear in the program. Is there any sort of fix for this?
Sorry, but you are missing the point: If your vendor provides versions for PC and Mac, it means he would still provide 32bit versions and 64bit versions for both platforms - 32bit for CS4 and before, 64bit for CS5 and above. Why don't you simply tell us, what plug-ins you are actually referring to?

Where did you get the plugins? All of Red Giant plugins have installers which require serial numbers. Optical Flares has an installer AND requires online activation. Without running the installers and following the activation process, the plugins won't work properly.
If the plugins don't appear in AE at all, as Mylenium says, they are properly not the correct versions for the bersion of AE you have.
