one reply says this "a similar message showed up on my son's computer. after reinstalling the psapi.dll file, another error message came up. in my case, i found he had a browser hijacker program, CoolWebSearch, installed. once we eliminated it using CW-Shredder, all of the problems disappeared. PSAPI.DLL was available at
