I recently went through the same installation fun, thanks to a computer failure. I too tried to set up things using separate user accounts, but I quickly determined that it simply wasn't going to work. Our computer is set up using domain logins, which allows access to the computer from elsewhere for data backup purposes. I set up an administrator account that can be used for operating the MS. Isodat was installed while logged in to this account and this is the only login account that Isodat will work with. I too tried to work around it by trying to redirect Isodat, editing the registry, etc, but to no avail. So I had to settle with the administrator setup. Maybe there is a gifted wizard out there who can set it up differently, but this muggle had to cut her losses and move on. On another note, has anyone upgraded Windows XP to SP3 with Isodat 2.0 and/or 2.5? My disastrous computer failure mentioned above happened right as I tried to do an update to SP3. So I was afraid to try to do it again on the new computer and settled for SP3. --Alison ________________________________ Alison Pye . [log in to unmask] Stable Isotope Lab Coordinator CREAIT .

It has been a FUN experience but with Roger Husted's (Thermo) expert assistance and occasional reference to the Isogeochem archives, I have been able to get things up and running. I have run into one problem which has both Roger and I puzzled. When I set up the system, I did so under an administrator account. As is my custom, I created a user account for the operators to use. When I tried to run the Isodat program logged in on this user account I got the following error messages: Fiberline not detected, using fake (we know this, we don't have fiberline communications) Error by open file D:Finnigan\Isodat\Global\~Graphics\\Meta_Mass_Spectrometer.emf Error by open file D:Finnigan\Isodat\Global\~Graphics\\Turbo_Pump.emf Error by open file D:Finnigan\Isodat\Global\~Graphics\\Rough_Pump.emf Error by open file D:Finnigan\Isodat\Global\~Graphics\\Small_Arrow.emf Note the use of "D" for the drive; this is the DVD, not the hard drive. After these errors, nothing else occurs; the program stops. I tried upgrading the user account to administrator status and putting the Isodat directory in the path but neither worked. Any suggestions/ideas?
