Licencing errors when running MIRO from Studio

GAMS MIRO
1

Hi,

I have a valid GAMS Single User Licence on Windows. When running models in GAMS Studio everything works brilliantly.

However, I started to have problems when launching MIRO. Specifically, when selecting “Run Base Model” in Studio I receive the following error: “Could not run GAMS. Exit Code: 7”. Code 7 represents a licencing error.

To make things stranger, I have been successfully launching MIRO from Studio for a number of days now and it just abruptly stopped working. Such a behavior could happen due to an expiration of a demo licence, but since MIRO is open source there are no time-limited licences…

Additionally, even when MIRO worked the number of variables was limited to 10. This is expected if there is no valid licence for GAMS system. But i do have a valid licence so it should not apply.

Any thoughts?

Best regards,
Radka

OK, the licencing error of MIRO got away once i returned to max. 10 variables to display by MIRO.
Question remains: what kind of licence is needed to get rid of this limit of 10 variables?

Best regards,

A MIRO Connector license. sales@gams.com should be able to help and also to provide a free evaluation license.

I hope this helps!
