Resolution

1. In Windows 10 virtual machine create two new local user accounts. Instructions for creating an account are available here.
2. Sign in to each account, then sign out of all accounts.
3. Sign in to one of the new accounts again.

4. Open Windows Explorer and navigate to the following directory of the other new user account (not the one you're signed into).

   C:\Users\<USERNAME>\AppData\Local\TileDataLayer\Database
