Since you can see the plugins in the list, they are installed correctly.
It sounds very much like missing Visual Studio redistribution packages. That is a package connected to the version of visual studio that last built the plugins - very technical but just FYI. Visual Studio is the development environment from Microsoft used by many.
Names of these are "vcredist_x86.exe" or "vcredist_x64.exe".
x86 is for 32-bit and x64 for 64-bit software that is to run, so both is good to install.
It should be in the install. You should not have to worry about it.
But you can get it working more quickly by hinting support about it.
Maybe the forum hosts have links directly to these needed. These can also be googled but you need to know which Visual Studio version 2005, 2008, 2010 or 2013 or something doing that. You can look in installed software in Windows which of these are missing - it doesn't hurt to have it all.
