Which is the most current VC++ and how do you find it on your system? Thank you.
It's not so simple. There are multiple version of it ( 2005 SP1, 2013 and 2015 ) and they can be updated by anything: a windows update, a .net update, another software, the sim itslelf, etc.
As I've said, depending on the version you had previously had and which software is running at the moment, you might have to restart Windows, when such libraries are updated.
But again, there's nothing in 4.3 that would prevent our software to run. In fact, we have been using 4.3 since several months by now.
