MIRO Database connection error

Post by Cyprien » 1 month ago

Dear all,

I'm learning GAMS, and for my modelling work, MIRO seems to be convenient for easier interactions with the model.
I have installed MIRO and followed the "getting started" steps, but it is impossible to launch a model on MIRO:

I tried with the demo models (transport and the others), as well as with my personal model, to run the program in Base Mode.
I get this message in the process log:

Code: Select all

FATAL [2021-09-23 11:46:58] 
(with the corresponding run date and time)

Then a MIRO window opens and displays the following message:

Please fix the errors mentioned below and restart MIRO:
Db: Database connection could not be established. Error message: Failed to load extension: The specified module could not be found.

This problem is not specified on the forum, and I couldn't find any relevant help on it...

I'd be very thankful if you can help me fix this,

Best,
Cyprien

Cyprien,

I assume you are on Windows and have some non-English characters in your username (like ä, ö, é)? MIRO currently does not support such paths on Windows. Please try to uninstall MIRO and install again for everyone (so that the installation files are located in C:\Program Files instead of C:\Users\). This should resolve the issue.

Best regards,
Freddy
