Shane,
The DisableLeasing registry key solved the "unrecognized database" problem for our customers, but it created one nearly as bad: a huge performance hit.
Our largest customer has about 9 Windows 10 workstations and a Windows 2012 server. Each client has an accde linked to a shared access DB (also an accde) on the server. They are running Access 2013 runtime on each workstation.
They were getting the "unrecognized database" error frequently, some days every five minutes or so until we applied the DisableLeasing workaround.
Performance was fine (more or less) until we applied the workaround, then it took a nosedive, and nothing we've done to date has improved it. It's so slow at times that we're probably about to lose them as a customer since we haven't been able to resolve it for them, and it's been several months.
Our other customers are experiencing the same performance hit even with fewer clients. They were also getting the unrecognized database error until we did the DisableLeasing, which slowed things down to nearly a crawl.
We need help, or we'll be out of business soon. Or at least out of the Access development business.
