I was testing a wizard installer today and realized that BAIN is not looking at the correct field on the SkyrimSE.exe file to pull the current version. Yes yes, I know, Bethesda is putting it in the wrong space and all that. Since we're not going to get THEM to fix that, it should be fixed on this end. Here's what the installer told me:

This is what you see if you right click the exe and check the details tab:

Hopefully isn't too big a hassle to fix.
