Strange errors when running programs.

Recently I've tried Windows10 and as I didn't like it, I revert to the W7. Because me being a moran as I am, I haven't done system image disk and had to set up everything all over again, but this time, when I've applied all the updates and installed all the software I'm using, so far, I encounter similar errors when trying to start two software that I had installed last time and that worked without any problems. Those are Voice Attack and FoxIt reader. As I've said, both those programs ware installed on my machine before trying W10 and worked flawlessly. What have changed them? I didn't add any "weird" software yet. All I did was applied win update on a fresh install.
Those errors are
Why is that? What is that? Is there a way to find out what this error is about?

Have you got all net framework updates (4.6.1) is the latest, but some progs require earlier versions.

I did run win update and thought this will deal with all of this. I know that I do have the latest .net cause I do remember marking this as to be installed. How do I "update" previous ver now as wel?

Earlier version 3.5 SP1, from here

Can you also check if you have Visual C++ 2005, and C++2013 installed

It's done.
Thank you:)
