How to Set-up User Groups in Windows in preparation for 21 CFR Pt 11 mode (NC-200, 250, 3000) or Secure Mode (NC-202)


Our 21 CFR PT 11 and Secure Modes utilize your institutions already existing windows infrastructure to allow tiered access to the NucleoView and NC-View software respectively. This means that you are not required to have a separate username and password for access to your NucleoCounter and may use your existing credentials.

This is done by the addition of three local user groups on the computer dedicated to your NucleoCounter, which are detailed below.

How to Set-up User Groups in Windows in preparation for 21 CFR Pt 11 mode (NC-200, 250, 3000) or Secure Mode (NC-202)

  • First, please ensure you have the correct version of windows by right clicking on the windows icon at the bottom corner of your screen and selecting “System

Here, you will see information about your computer, including the Version and edition of Windows installed. You should have Windows 7, 8, or 10 installed, and the edition should be Pro or Enterprise***Home Edition Windows Installations do not have access to create User Groups and should not be used if you intend to use either 21 CFR PT 11, or SecureMode***

Once your version of windows is confirmed, please right click on the windows icon in the lower corner of your screen once again, this time selecting “Computer Management

Once the computer management screen is open, please select the option on the left hand menu “Local Users and Groups” and then double click on the “Groups” Option

Once the groups panel is open, please right click in the white space and select the option “New Group

After selecting “New Group” a new window will appear allowing you to name and create User Groups for your instrument.

  • These group names are case sensitive and are particular for your series of instrument.
  • For NC-200, NC-250, and NC-3000 instruments, these groups must be named the following: “NucleoViewAdmin”, “NucleoViewSuperVisor”, and “NucleoViewUser”

For the NC-202, these groups must be named “securemodeadmin”, “securemodesupv” and “securemodeuser”

Once created, you may now double click on the user group of choice and assign access based on your organizations policies.
