Yes, I had already used that during the previous uninstall issues. Initially I tried using the PDN update, but that failed (over and over). I downloaded and tried running the new installer, and it would fail trying to uninstall the prior version. So I tried uninstalling PDN directly from the Windows/settings/apps, and got errors. I ended up finding and using that utility previously, which actually was insufficient to get PDN uninstalled (I ended up using another utility afterward to get it uninstalled). Then I ran the installer, and it failed. So I downloaded the installer again, and it failed. Over and over. I noticed the installer had been created on Oct 22, which is why I came here to ask if there is an issue with the installer, because it's looking for a file (supposedly extracted from the installer to the install staging directory) which isn't there.
I'll try the utility again (both "install" and "uninstall" to allow it to do its incredibly long running registry checks), but I don't currently have PDN installed.
