Warning
The FLO-2D Plugin packages a bundled version of the h5py library for Stand Alone QGIS programs.
In some QGIS environments, the h5py binaries lock the plugin folder.
This may prevent the plugin from uninstalling, updating, or overwriting files during installation.
If the plugin cannot be removed or updated:
Close QGIS completely.
Open the plugin directory:
C:\Users\YourUserName\AppData\Roaming\QGIS\QGIS3\profiles\default\python\plugins\
or for QGIS 4:
C:\Users\YourUserName\AppData\Roaming\QGIS\QGIS4\profiles\default\python\plugins\
Delete the entire
flo2dplugin folder manually.Restart QGIS.
Reinstall the FLO-2D Plugin.
Open to the Plugin Manager and Find the Install from Zip tab.
Load the FLO-2D Plugin and install it.
