Hi all,

Errors will occur when starting the SWAT+ model as well as the SWAT model.

The versions I used were: QGIS 3.34.14, QSWATPlus 3_64install 2.4.1, swatplus-windows-installer 3.0.8, swat.check-installer 2.0.1

Below is the error message:

Cannot find project database template C: \Users\24319\SWATPlus\Databases\QSWATPlusProj.sqlite. Have you installed SWAT+ as a different directory from C: \SWAT\SWATPlus? If so use the QSWAT+ Parameters form to set the correct location.

Cannot find reference database template C: \Users\24319\SWATPlus\Databases\swatplus_datasets.sqlite. Have you installed SWAT+ as a different directory from C: \SWAT\SWATPlus? If so use the QSWAT+ Parameters form to set the correct location.

Cannot find executable mpiexec in the system or msmpi.dll in C: \Users\24319\SWATPlus\TauDEM539Bin: TauDEM functions will not run. Install MPI or reinstall QSWAT+.

Is there anyone who can provide some suggestions or tutorials on how to solve this kind of problem?

Thanks,
zhao
