Error c:/wamp64 or PHP in PATH (1 reply)

I've just installed wampserver 3.1.4. It seems to operate successfully but it displays on the bottom of the dashboard this error message:

Error c:/wamp64 or PHP in PATH

So far as I know, this hasn't yet affected the performance of wampserver, but I would like to get rid of the error if possible. Any help about what causes this and how to deal with it much appeciated
