Both of these apps allow a degree of automation, so I would try to create an object of each type and if you get an error, then it isn't there.

e.g.
PRIVATE lError, loObj
lError = .f.
ON ERROR lError = .t.
loObj = CREATEOBJECT("outlook.application")
ON ERROR
IF lError
? "outlook isn't here!"
ENDIF

I'm not sure what the class name would be for WinFax pro - if you search the archives, there are plenty of examples of WinFax automation.
