Excel slow after first install

Hello,

I recently installed excel on my computer for a College class I'm taking. I am running Windows 10 with 16 gig RAM, and AMD Ryzen 5 3.85GHz processor. But excel is taking forever to open or do anything. I haven't even made a single entry yet because it lags so much. Other programs run smoothly when excel lags. In fact I writing this right now as I wait for excel to boot. I've checked for and installed updates, reset my machine. Also ran CCleaner and an Antivirus scan to be sure. Does anyone have any suggestions?

EDIT: Issue was caused by conflict with existing program. I found the right one by going to task manager and stopping programs one at a time until I found the right one. Hopefully this will help someone in the future.
