The ADInstruments GLP Client is dependent on the version number of the LabChart software. That is, the first two digits of the GLP Client and LabChart should be identical (e.g. GLP 6.2 will operate with LabChart 6.2.x, and will not operate with LabChart 6.1.x). Before updating software, laboratories should check their standard operating procedures. For information about the correct versions of GLP Client, Server or LabChart please contact your local ADInstruments representative.
