Will this work?

Hi

I want to have PowerPivot and other nice excel add-ins but only have an Office 365 Home Premium Subscription Version of Excel which does not have these add-ins.

Simply, can I buy and install a standalone version of excel (non-commercial preferred as my use will be just that) and run that standalone version to get these add-ins? Will this affect the rest of my Office 2013 programs?

Thx
