Try the following:
- start commandline app as administrator user (in different Windows versions it is done different ways, also depending on your UAC state), in common case you need to find cmd.exe and start it with the right mouse-button “As Administrator”
- In that commandline window, type:
sqllocaldb info
(for more clarity I’ll write in CAPS first word SQLLOCALDB)
you have to get something like this:
ObsidianControlSystems
ObsidianOnyx
If one of those missing, you need to create it by hand, do the following - type in the forementioned commandline window (for example you want to create ObsidianOnyx database, actually, what I needed to do to overcome 27502 error):
sqllocaldb create “ObsidianOnyx” -S
That’s it!
P.S.: Actually, this is some mistake in createobsidiancontrolsystemslocaldb.js script inside the installer, making it do the wrong stuff on some systems (I get it on Windows 7 SP1 x64). If somebody Obsidian stuff reading it, correct it, please, or let’s try to debug it together.
