Maintenance: February 8, 2024

On February 8, 2024, our partner WIBU-SYSTEMS will be carrying out maintenance work from 5 p.m. to 7 p.m.

What could this mean for you?

During this time, it will not be possible to activate SYMplus™ licenses via The License Manager for managing your license(s) will also be affected. A software update may be affected.

If you have already activated a SYMplus™ license and none of the above points apply to you, you can work as usual.

Thank you for your understanding and please do not hesitate to contact us if you have any questions.
