ICP 7800 communication

For some reason, I rebuilt the ICPMS computer and re-installed the MassHunter 4.4 on the computer (Win 10 Enterprise). When I tried to connect the masshunter and the ICPMS, by checking the "check firmware" box. It said "masshunter needs to be updated because firmware is newer than expected version. It will go offline." If I uncheck the  "check firmware" box, it was fine and I could control the instrument. However, when I tried to run batches, it had an error "Could not load file or assembly "BaseTof.dll" or one of its dependencies."

Does anyone know how to fix it?

  • With 4.4 you have to install some Microsoft Patches manually.

    You can find them on the installation disc in the folder "Microsoft". Be sure to install all of them. And yes, there are some 32 and 64bit Versions, all of them are needed. In later Masshunter Versions, these Patches are installed automatically.

    Hope this solves your Problem

    Best of Luck
