I'm relatively new to GEANT. I installed the packages last year (4.10.00 p02, on a Windows 7 computer using MS Visual Studio Express 2013), and by November was running the simulations I needed, with just some optimisation of the detector needed. Then other work took priority, and I got back to my simulation needs at the start of March and successfully got my simulation reproducing experimental data and started on the simulation of things I couldn't measure in the laboratory. I still need to see if I can optimise the efficiency ... but that would be a subject for a different forum.
I hit a problem on Friday, when the copy of Norton installed on the computer expired and wanted someone to pay to renew it. So, as the university has a site license, we installed Norton from CD. When the computer was rebooted following that installation, I could no longer run my simulations. I was getting a message saying "The program can't start because G4Tracking.dll is missing from your computer. Try reinstalling the program to fix this problem". The first thing I did was check, and all the .dll files were where they were supposed to be, the PATH variables had not been reset or anything obvious.
So, I reinstalled the program. This fixed that problem, but instead I got an error relating to the G4VisManager - error messages that the entry point for "IgnoreStateChanges" could not be found in the .dll file. While waiting for my registration to be approved here, I 'fixed' this by commenting out the relevant lines from the G4VisManager.hh file - which allowed the simulation to run, but does not seem to be the right thing to do.
Things still aren't back to the pre-Norton update status though. I had made several folders into which I had copied the executable and .mac files, which had allowed me to run several simulations simultaneously taking advantage of the multiple cores in my processor to build up simulation statistics at a faster rate. However, now when I try to run a second copy of the executable I get a missing .dll file error (this time G4Tree). Clearly it's there, because the first copy of the executable had no problem finding it.
Has anyone experienced anything similar and have advice? It would be useful to be able to run the simulations without changing the distributed code, and to run several copies simultaneously because I can't afford to spend months running the simulation.
