I was initially hesitant to upgrade to High Sierra because I thought I would have trouble with a couple of 32 bit applications that I use a lot for which there is no upgrade.
32 bit apps were originally scheduled to bite the dust in macOS 10.14 Mojave, but it now looks like it will support them and 10.15 will be the cutoff; the reprieve will be nice, but we'll have to face unpleasant reality at some point.
I've had absolutely no problems with 32 bit apps in High Sierra.
Have you tried rerunning the latest Sierra Combo...if macOS will allow you to do so?
