When using the “Add or Remove” programs function in Windows 10, sometimes errors will prevent uninstalling Qtegra, as well as, other plugins ex: ESI plugin, Teledyne Cetac.




The programs can be manually deleted using the command prompt and registry editor.

  1. Open the Registry Editor by going to the following computer location “C:\WINDOWS” and choosing the regedit application. 
  2. Go to the location below in the registry editor, and find the UninstallString. The file location under the Data column will be the command line used in the command prompt for un-installation.

  2. Type cd\ to clear the directory, and then type the UninstallString from the Registry Editor to begin uninstalling the program.
