Root Certificate Revocation

A high level root certificate has recently been revoked on Windows machines. This is an old certificate, so it does NOT affect any recent versions, but downloads of some old versions (specifically FX Draw 5) may not work on current computers. Efofex has no way of rectifying this issue as it is due to certificate from a certificating authority.

If you are a current subscriber, you can ignore this issue. Just make that you are using a reasonably up-to-date version. This issue only affects downloads which were released approximately 10 years ago.

If you still use one of the old, affected versions of our products (especially FX Draw 5), you may be forced to upgrade to a newer version.
