Get ready for a huge and confusing installation project
Trying to install VB6 and VS6 on a Windows 8.1 system is a nightmare. The documentation that comes with it is, of course, ancient and resources on the web lead you in fifty different directions none of them working. Gave up on trying to install studio and just installed VB6. Can load an old project but it won't let you add controls to a userform. The one thing I got out of it was the MSComm Active X (licensed) control that I can use in VB for Applications. This control should have come with VBA natively. Definitely not worth the going price on these packages. Maybe a $20 value for the controls.
I built numerous engineering programs on Win 7 with no real problems and learned a lot
VB6 can be a problem to install with Win 10 but is straightforward to install and run on Win 7. I suggest purchasing several VB 6 books to help you understand better how to build programs that are fun to run and, for my engineering programs, useful in my profession (and by my associates). The final programs can be compiled to .exe files that I run on my present Win 10 machine.
Building the GUI is fun and the result is both attractive and can be intuitive to the user. I use it for combustion calculations, gas heat content, heating value estimation, archives for property data, estimation routines for physical properties such as boiling points, psychometric parameters and the like.
This version of Visual Basic (6.0) installed easily on Windows 7 and ran perfectly.
For installing VB6 on a Windows 7 CPU, google "Installation of VB6 on Windows 7".
