As for W7 32bit driver support, that was dropped late 2018 (no driver listing anymore).
This looks to be the last driver that was made:
Please follow link: Radeon™ Software Adrenalin Edition 18.7.1 Release Notes | AMD
I remember that the 32bit driver provided by 18.7.1 is not available for graphics cards after RX400
I remember last year I asked AMD and their reply was that RX400/500/Vega does not support 32bit but I forgot how to contact them. I remember I asked for a fix before but they didn't fix it
I saw that AMD's latest driver since July has missed the Win7 part of the driver, and I want to say that it is required.
You are correct, I have looked further back and you would have upgrade to 64bit..
There is no driver for 32bit..
