The installer that ran when you downloaded this app/plug-in from Inventor App Store has already installed the app/plug-in.

You can unload the plugin without installing it by unchecking the "Load" checkbox associated with the plugin in the Inventor Add-In Manager.

You may have to restart Inventor to completely unload the application. To remove the plugin completely, RMB click and uninstall the application using the App Store Manager tool, located on the Ribbons Tools tab > Options Panel.

Note: Please note that Inventor files are NOT downward compatible.

To stop the app being activated upon opening the model ipt file, follow the menus as "iLogic -> Event Triggers -> After Open Document", remove item "CouplingSelector" from there. Please don't change parameters with the Parameters (fx) command in Inventor, or through the model itself. That might disturb the relationship among parameters.

As trial version, commands on the right side (Export 2D DXF, Save as XML, HTML Report) are not implemented. They can be done for our clients.

The ipt can be used directly in Autodesk® Inventor® 2014. and next releases
