Hi Herb, In addition to Gerard's helpful hint (yes, I'm a member of that club too; forgetting to run the configurator before running workspace after a laptop installation) there is also the issue of service packs to consider. Service pack release of the off-line installation must match the service pack of your instrument PC installation. Best, Wolfram ________________________________________ From: Stable Isotope Geochemistry [[log in to unmask]] On Behalf Of Gerard Olack [[log in to unmask]] Sent: 27 August 2007 17:48 To: [log in to unmask] Subject: Re: [ISOGEOCHEM] Isodat 2.5 Problem HI Herb-- After install, did you run configurator first?
