In other words - it can be anything - you'd have to
look at the system
requirements of the software to know.
.NET Framework 1.1
.NET Framework 2.0
.NET Framework 3.0
.NET Framework 3.5
Normally any installation that needs either of those
will tell you so at install time and probably is
indicated in the docs for that program. But once it's
installed there is little you can do to be sure one of
them is installed with it.
If you have none of those and everything works well and
nothing is asking for one of those, then you don't need
them.
If you're trying to figure out what's useing the one/s
you already have, try renaming their folder name to
make them un-findable and see if any programs complain
that it's missing. If it's needed, the program needing
it should plainly state so in an error message, or will
at least quit working. In which case name the folder
back of course.
When I rename such folders, I usually put a "-" in
fron tof the name; makes them float to the top of an
alpha listing in Explorer so they're easy to find.
