When I was fixing AE I found out that my computer doesn't have "PproHeadless.exe"

My AE program kept stopping at the "Initializng Media Cores" screen so I went online to troubleshoot and found out that there were a couple programs I didn't let through my firewall. So I allowed most of them except for one because I couldn't find it ("PproHeadless.exe"). Can someone help me figure this out or please give me a download link to the file or anything that can help me get back into AE? Thanks in advance
