Problem with Xpress installation: Module `mminsight' not found.
I attempted a new installation of Xpress and Insight on a Windows 11 PC. (Downloaded files yesterday.) xp9.8.0_win_x86_64_setup.exe and FICO_Xpress_Insight_5.16.1_Community_Edition_setup.exe installed successfully in their default directories. I opened a project in Workbench and tried to compile it - got error:
Mosel: E-350: Module `mminsight' not found.
Indeed, couldn't find mminsight.dso in either of the two installation directories. I found it in file insight-developer-kit-5.16.0-win_x86_64.zip but the installation instructions do not tell where to extract this file. Please advise.
Thank you,
Miroslav

Hi Miroslav,
Thank you for reaching out, and welcome to Xpress Insight!
The mminsight.dso module is indeed not included in the base Xpress installation — it's part of the Insight Developer Kit (IDK), which needs to be extracted separately after installing both Xpress and Xpress Insight.
To resolve this, please extract the IDK archive (insight-developer-kit-5.16.0-win_x86_64.zip) directly into your Xpress installation directory (typically C:\xpressmp). When prompted, confirm that existing files should be overwritten. After this, the mminsight.dso file will be located in "C:\xpressmp\dso\" and Mosel/Workbench will be able to find it automatically.
Please let us know if you run into any other issues. We're happy to help!
Best regards,
Bruno
