6. Run SFC and DISM

Corrupted system files may cause application errors like NW_store.exe, but luckily, there are two built-in tools that can help to identify and repair such bad system files. The whole process could take some time, and we suggest you don’t run any other programs when doing the tests. To run these tools:

6.1 Scan corrupt files with System File Checker

1) On your keyboard, press the Windows logo key and R at the same time. Type cmd and press Ctrl+Shift+Enter at the same time to run Command Prompt as administrator.

Click Yes when prompted for permission to make changes to your device.

2) In the Command Prompt window, copy and paste the following command and hit Enter.

sfc /scannow

3) System File Checker will then scan all system files and repair any corrupted or missing ones it detected. This may take 3-5 minutes.

4) After the scan, try to open your NW.js again to see if the crashing problem still persists. If so, move on to the next test:

6.2 Run dism.exe

1) On your keyboard, press the Windows logo key and R at the same time. Type cmd and press Ctrl+Shift+Enter to run Command Prompt as administrator.

Click Yes when prompted for permission to make changes to your device.

2) In the Command Prompt window, copy and paste the following commands and hit Enter after each line:

dism.exe /online /cleanup-image /scanhealth
dism.exe /online /cleanup-image /restorehealth

2) When the process finishes:

  • If the DISM tool gives you errors, you can always try this command line. This will take up to 2 hours.
dism /online /cleanup-image /startcomponentcleanup
  • If you get Error: 0x800F081F, reboot your computer, then open Command Prompt as administrator again (step 1) and run this command line instead:
Dism.exe /Online /Cleanup-Image /AnalyzeComponentStore

When these tests are done, run your NW.js again to see if it still crashes. If the problem still persists, please move on to the next fix.
