Q100320: Unable to use RLM floating licenses with Nuke 11.0 and above or Mari 4.0


If you've downloaded the latest Nuke 11.0 or above or Mari 4.0 or above, and while you are on current maintenance, are encountering licensing problems with an existing RLM floating setup, you may have come across a known issue due to the update of the internal RLM version within Nuke 11 and Mari 4.0.


We have upgraded the version of RLM used in our central licensing code from RLM 9.3 to 12.2.  At the time of writing the new version of the licensing code has been introduced in Nuke 11.0 and Mari 4.0. 

The previous version of the Foundry Licensing Tools (FLT) 7.1v1 included RLM 9.4bl4.  This could lead to problems checking out a license on some networks if the version of RLM within the product is newer than the version running on the license server.


We have now released a new version of the Foundry Licensing Utility which uses RLM 12.  This is now fully compatible with Nuke 11.0 and Mari 4.0 and above.  If you have a valid license for Nuke 11.0, or Mari 4.0 and above but were unable to run them using FLT 7.1 then upgrading your FLU
