This computer can't be used due to license violations.

Good day! I used a free license on two accounts ( mail and calendar). Recently, the client started to give out the message: “This computer can’t be used due to license violations. Contact support.” What can I do to solve this problem? Thank you.

This is most likely because eM Client suspects that you are using the Free License for business use. That is a violation of the license policy. If you use it only for personal use, contact eM Client at the address given.

If you are using it for business, then you need to purchase a Pro License.
