Info: Clean installation of SummaFlex

Modified on Tue, 23 Oct 2018 at 11:18 AM


Sometimes Summa support will advise to make a clean install of SummaFlex. In this case you will have to follow the procedure below to make sure all files are properly “removed” before you start with the installation of the software.

Instead of “removing” the old data Summa does recommend to move all program files data to another location on the hard disc. When needed you still can retrieve critical files.

Backup old SummaFlex data

Copy the current SummaFlex folder to another location on the hard disc;

For example copy from “C:\Program Files (x86)\Summa\SummaFlex Pro” to “C:\Program Files (x86)\Summa\SummaFlex Pro.old”


Uninstall the old version of SummaFlex

  • Press "Windows-key" + "R", the “Run” window will open
  • Enter: “appwiz.cpl”, Windows “Programs and Features” window will open: 
  • Right click “SummaFlex Pro” and select “Uninstall” 
  • Follow the instructions on the screen
  • Go to windows explorer and delete the original SummaFlex Pro folder:
  • C:\Program Files (x86)\Summa\SummaFlex Pro: 

Install the new version of SummaFlex

  • Make sure there is only one setup file in the folder where you did download “summaflexpro(x).exe” Clean install:When you have two or more setup exe-files in the same folder than SummaFlex could run an old setup.
  • Follow the instructions on the screen. When serial number or ECFN file is needed than you can download this data from the Summa website: 
  • Setup SummaFlex, if needed also setup the barcode workflow (see installation manual)
