Please note that this version of CHEMCAD will NOT run with License Manager 7.2.
Organizations currently using License Manager 7.2 should contact Chemstations about upgrading to RMS License Manager. If you currently use License Manager 7.2, please DO NOT attempt to install the latest version of CHEMCAD until this has been done.
Not sure if you're using License Manager?
In CHEMCAD, select Tools > Options > Licensing and then look for 'License Manager' in the Type column.
Do you compile your own custom UnitOps, K-values, or pipe methods? Advances in CHEMCAD 6.3 made it necessary for users of usradd.dll to recompile with the new usradd workspace before loading that .dll into CHEMCAD 6.3 or later. Please contact Chemstations at 1-800-CHEMCAD for more information about this important maintenance task. We will be happy to assist you.
