Still, please also install support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads .
And, if you want to try to run with QuickOPC 2020.2, have you rebuilt your app with units regenerated with type libraries from Quick OPC 2020.2? Taking an app comppiled with units generated from older type libraries won't work.

You are installing a redistributable from QuickOPC 2019.2 and using it with 2020.2. I tmight be different. So first thing to do is to use the one for 2020.2 with 20202.
As an additional undocumented step, please also install this: support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads (because the link in the product/documentation might be incorrect).
