Problem description #

When trying to start AxisVM, an error occurs with the spro_aex64.dll file, and the software does not start up.

The Sentinel driver which is used to protect the software and certain USB driver software interfere with each other.

Make sure whether a USB device (e.g. flash drive) is connected to your computer.. If yes, remove it! Sometimes it causes a problem, because USB device (e.g. a SanDisk pendrive) “conflicts” with the Sentinel driver.
If there is no connected flash drive and the program doesn’t start, try to launch AxisVM with admin rights.
If it doesn’t help, try to rename the spro_aex64.dll to another name (AxisVM may work properly without this dll).
