Can't upgrade mission planner

i’ve searched and can’t find anything.

i can’t upgrade from inside mission planner, i’d like to get the beta mission planner up and running for 3.3 copter.

I get this error.

“the following feature couldn’t be installed”
.net framework 3.5 (includes net 2.0 and 3.0)

the referenced assembly could not be found
error code: 0x80073701

this is a surface pro 2, 64 bit.

thanks for the help.

nevermind, it was windows issue.

i couldn’t install .net framework.

i did a refresh, all set now.

what a pain.
