The problem is not the apps, which once installed, run like banshees. It's the installer that is giving me fits when it attempts to create a new directory in the filesystem. For most of my apps, I have been using for years, I know the file structure and can create it manually, after the installer fails. Then the application will run. But I am now installing some of the new photo apps from Topaz, and am, as yet, unfamiliar with their structures. With their help, was recently able to have success installing their software. The problems was all related to where their application expects to find a specific folder for saving the images being created.
What steps were required to get Topaz to installer? That may provide some clues for us. Also, are these third party apps fully supported in Ventura and are you using the most recent version of these apps? macOS includes lots of new security features and you may need to configure those security features to allow an app to access certain locations and devices.

Are you using any anti-virus apps, cleaning/optimizer apps, or third party security software? If so, then these apps do interfere with the normal operation of macOS and could be the source of the problem. Plus these types of apps are not needed on a Mac, so if these are installed, then uninstall them by following the developer's instructions. You can try booting into Safe Mode to see if the apps will install since Safe Mode prevents the automatic launching of third party software during boot & login. If you want us to check out the Mac's configuration, run EtreCheck and post the report here using the "Additional Text" icon which looks like a piece of paper.
I believe my problem would go away if I could do a "clean install" of just the Ventura Installer.
I would first try Safe Mode, and I would also try @bailier's suggest for testing with another macOS user account.
If you want to perform a clean install of macOS, then you have several options if you have an Apple Silicon Mac:
When using the first two options, you will need erase the drive by using the instructions in this Apple article (also included in the "Recovery Mode" article linked above. The third option does all the setup automatically, but I don't know what OS it will put on the Mac (original factory OS, or the latest supported OS).
