If you are running a version of QC-CALC prior to 3.4, upgrade to 3.4 first. This will get all of your data up to the latest revision. If you currently have QC-CALC 3.4, update to the latest revision first for the same reasons. In this case, contact Prolink for help getting your QCC files to the latest version of 3.4.


This article gives the general steps to upgrade your existing copies of QC-CALC 3.4 to QC-CALC 4.0. There are generally two steps; upgrading the software itself and converting your existing data (QCC files) to the new format (QCQ files). If you are choosing to use SQL Server, there is an additional setup step of creating the database and assigning permissions. If you use the Create Database button on the Tools > Options > Data Storage screen (when SQL Server is selected at top), the wizard will create the database and assign a user account for you. The only thing you will need to know is the server name where SQL Server is installed and a system administrator account that has the privilege to create a database.

This involves installing the software and copying all settings from your previous version. As outlined above, start with the data collection software (QC-CALC Real-Time, Gagestation, QC-Gage).
  1. Install QC-CALC 4.0 on the same PC as QC-CALC 3.x if possible. If not possible, skip to Copying Settings Manually section below after installation.
  2. On first run of QC-CALC Real-Time, a message will appear saying QC-CALC 3.x was detected and offer you an opportunity to copy your settings forward. Choose Yes to keep your previous version's settings and use them with 4.0. QC-CALC will copy all settings and related files from 3.4 and use them going forward. If you are using the Administrative Tools, 4.0 will automatically be redirected to the same user group as your previous version.

  • If you are using SQL Server as the database type, choose Tools > Options > Data Storage. Choose MS SQL Server from the Data Storage Type dropdown and enter your connection path into the 4 fields on the Data Storage screen.
    NOTE: Report templates will not be copied from the old version, but there is a new Template Converter application that can help you convert your existing report templates to the new 4.0 version. If you have not customized your report templates, you can use the newer version of the templates that are installed with QC-CALC 4.0 as they are the same. To convert the templates, select Help > Launch Template Converter and follow the instructions.

    NOTE: You can convert multiple templates at once by selecting multiple files from the source dialog.
    Copying Settings Manually
    NOTE: Skip this section if you installed QC-CALC 4.0 on the same PC as your previous version.
    1. Shut down any previous version of the software that is running. This will ensure you are not writing to the settings files as they are being copied.
    2. Copy the following files from the old version's directory (i.e. c:\Prolink\QC-CALC 3.4\) to the new directory (i.e. c:\ProgramData\Prolink\QC-CALC 4.0\). Due to Microsoft's software requirements there are two new directories in QC-CALC 4.0; the ProgramData directory and the Users\Public directory.
    The directories are typically the ones below unless you installed QC-CALC in a different directory than the default. In this case, the lowest folder will differ slightly in name.
    ProgramData directory: C:\ProgramData\Prolink\QC-CALC 4.0
    Users\Public directory: C:\Users\Public\Prolink\QC-CALC 4.0
    WARNING: Do not copy any files not listed here.
    Copy the following files to the ProgramData directory:
    • Admin.ini - This may be hidden. Turn on "hidden files" in Windows Explorer.
    • AskValues.ini
    • ConvertTemplates.ini
    • QC-CALC SPC-ScreenSettings.ini
    • QC-CALC.ini
    • QCCalcOverrides.ini
    • QC-CALC-RT.ini
    • QC-CALC-SPC.ini
    • RealTimePlots-ScreenSettings.ini
    • TrainingCmm.ini
    • Update.ini
    Copy the following files to the Users\Public directory:
    • AssignableCauses.dat
    • CorrectiveActions.dat
    • *_setup.txt - Files of this style may or may not exist depending on your machine type (i.e. modus_setup.txt or metris_setup.txt). If they exist, copy them.
    Data Conversion
    You must convert your existing data files (QCC) to the new format (QCQ or SQL Server) in order to use them in 4.0. It is important to note that converting your QCC files to QCQ or SQL Server does not change your QCC files in any way. It only copies the data and settings within them to the new database.
    1. Shut down any previous versions of software to stop any new data from being collected during the conversion process.

    2. In QC-CALC Real-Time 4.0, choose Help > Launch Data Converter.

    3. By default, the From value is set to QCC files and the To value is set to QCQ. As the To value, choose either QCQ or SQL Server as the case may be. Click Next.

    4. On the Source screen, navigate to the path where there are QCC files at the top. You can then choose to convert all files or choose a specific list that will be converted. Click Next.

    5. On the Destination screen, do the following based on database type.
      For QCQ files, choose the new path where your QCQ files will be stored. This will typically be on your network. If you are on the local PC, choose C:\Users\Public\Prolink\QC-CALC 4.0\Data\. Click Next.
      For SQL Server, type the connection path (server, database, user, and password). Click Next.

    6. On the Additional settings screen, change the Assignable Cause or Corrective Action path if desired and click Next. For SQL Server, optionally choose to enter a location in the "Location" settings box at the top.

    7. On the Process screen, click Start Conversion. The conversion process will start and progress will be displayed throughout the process. If you have a lot of QCC files, you may want to start this on a Friday night to allow time to process.
    Once the process is complete, it is recommended that you remove all QCC files (copy them to an archive location) to prevent future confusion. This includes all satellite files that go with the QCC files including files with the extensions QCN, NTS, P11, EIF, ET3, etc.
