A JavaScript error, like the one shown below, is caused by a corrupt or missing x86 Microsoft Visual C++ redistributable file. Having an x64 redistributable is not and can not be a substitute for the x86 version. Graphical Analysis, Spectral Analysis and Instrumental Analysis are 32-bit (x86) programs.
Note: When installing Graphical Analysis, Spectral Analysis, or Instrumental Analysis using a silent installer, the x86 redistributable must be installed manually if not already installed on the computers.
Fixing the Error
- Go into Add/Remove Programs and check to see if you have the Microsoft Visual C++ x86 redistributable, version 14. The listing will be similar to…
Microsoft Visual C++ 2015-2019 Redistributable (x86) 14.29.30133
Note: x86 and a version of 14.xx are most important; the exact year and version can vary.
- If you do have the x86 redistributable, remove it. If you do not have it, skip to step 4.
Note: Make sure you don’t remove the x64 version by mistake. Doing so will not affect the Vernier Analysis apps, but it will break other applications that depend on that redistributable.
- Reboot your computer.
- Install the x86 redistributable. The file is here: vc_redist.x86.exe
Note: The file can be distributed silently using the command: “vc_redist.x86.exe /q”.
