need to get a usable DaVinci Res version for my oldie comp

hello ..since days I'm digitizing old VHS-tapes and I'd need to get a suitable version fo DaVinci Resolve for my Computer. Well, it's an older one, but still quite okay and fast enough with everything else, I'm dealing with.
my GPU (NVIDIA GeForce8400GS) is an older one, I know, but works with the latest driver, of course
it's got OpenCL, CUDA, OpenGL3.3 and so on
RAM I have 16GB and the CPU is okay-fast ..Win10 / 64bit
I failed in installing the latest versions of DaVinci Res (19 or 20) of course, because my PC just can't handle it. So I went back to older versions 18, 17, 16, 15 but I even couldn't start the program with the installing files, I could find on the Blackmagic-Download page (messages like:
didn't find the point "clEnqueueMarkerWithWaitList" in the DLL "C:\Program Files\Blackmagic Design\DaVinci Resolve\Resolve.exe" and so on (indeed, there is no "resolve.exe" there)
I even went down to version 14, at first it seemed to work but obviously there are so many things missing and I guess, it's just a corrupted installation-file ..I just don't know - it sucks
Could anybody show me a link to a working full-version, which I could use? Nothing is working, so far.
Thanks, Anita
