I hate to summon the lightning and spark some life into a zombie topic, but this is the most recent one I can find, and it is faintly related to my current problem.  At least, to the extent that PzDB has abruptly stopped working for me.

Looking about the 'net for MS Access, I see hints that a Windows 10 update might be at fault.  PzDB runs, and lets me look at my database, do searches, drag and drop things in Poser as usual.  I can add and remove keywords from a character. What it won't let me do is update even a single record, let alone a catalog. When I try, it tells me that perhaps I didn't specify a database on the command line because it can't find it. Then it crashes and disappears.

I've done all the standard fixes and troubleshooting: use of the Compression/Repair program, backing up my files and  re-installing PzDB, formally uninstalling PzDB and re-installing it, formally uninstalling it, editing the registry to remove the entries, and re-installing it, and even installing it on a different hard drive. I've tried unsuccessfully to roll back the latest Windows update, and even, at one person's suggestion, tried running it in compatibility mode for Windows 8.

I haven't heard from my friend at Rocketship for a few years, and I have exceeded my level of technical expertise, and all of the helpful suggestions he's made over the years.

Now it's time to ask everyone else, as I've exhausted my resources, and I'm developing tunnel vision, unable to think of new possibilities to try.
