Permissions problems creating the appropriate directory. Since both updates exhibit the exact same error, it must be top level installer code bug common to both products, and not any code resources for just one or the other.
You guys have been great for the last year with frequent updates and smooth as silk installs, but you did have major installer problems a year ago, and found your coding mistakes quickly and re-issued updated installers.
Looking forward to that same fast response this time. And no beta testing, at least not on Catalina Mac. Who will make the walk of shame and admit their lack of attention to detail??
