When launching MassTransit Enterprise or Professional, the following error message occurs at startup:

Missing Hardware Key

After dismissing the error dialog, MassTransit fails to open, returning the user to the desktop.

This message only appears where USB hardware keys are implemented.

MassTransit runs and currently ships without a dongle, but for those customers running older (5.x and later) versions of MassTransit, the option is available as well. In order to convert your dongled MassTransit server to a dongle-less version you will need to obtain a dongle config file from Acronis.  If you are interested, please contact us at or and your rep will get in touch with you to begin the process.


Acronis occasionally needs information about your MassTransit dongle in order to perform upgrades or sidegrades.

An application called "DisplayDongleInfo" is used to collect the information from the dongle and save it to a text file. We then ask you to send that text file to Acronis in order to complete your upgrade/sidegrade.
