Failed to open database, error: unable to open database file

My enviorment:

3 machines with Solidworks and a Toolbox on network.

Update process:

Update Solidworks installation from 2018 to 2019, before the update i copied the toolbox folder from network to my machine, them i specified the path of toolbox during installation, and updated without errors or warnings.

After the update i copied from my machine to network again, the path as it was before.

What is happenning?

I can`t open the tollbox configuration tool, i get this error.

But when i use the toolbox of my machine it works, with the toolbox on network i get the error above.

What i did?

Tryed to use the toolbox in a local path and works when i use a network path i get the error.

I already contacted my VAR, at the momment no solution, that`s why i am here.

Ladies and gentleman i need help with that error.

Thanks in advance.
