How can I fix Skype error 0x80070497 in Windows 10?

1. Use Command Prompt

  1. Start Command Prompt. You can do so by pressing Windows Key+ X and choosing Command Prompt (Admin).
  2. Now you need to stop BITS service and Windows Update service from Command Prompt. To do so execute these two commands in Command Prompt:
    • net stop bits
    • net stop wuauserv
  3. Next, delete the qmgr*.dat files. To do this enter this in Command Prompt and press Enter:
    • Del “%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat”

If you’re trying this solution for the first time, skip this step and go to step 5. If you have tried all the steps already but with no success, repeat all the steps again, but this time don’t skip this step.

This is more aggressive method so use it carefully. Since this is aggressive method, we asked you to skip it before, but if you have tried all other steps while skipping this one, this time try these steps as well.

  1. Run these three commands in Command Prompt to rename the folders. Remember to press Enter after each command:
    • Ren %systemroot%\SoftwareDistribution\DataStore *.bak
    • Ren %systemroot%\SoftwareDistribution\Download *.bak
    • Ren %systemroot%\system32\catroot2 *.bak
  2. Next you need to reset the BITS service and Windows Update service to the default security descriptor. To perform this, you’ll need to enter these commands in Command Prompt:
    • sc.exe sdset bits D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)
    • (A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)
    • sc.exe sdset wuauserv D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)
    • (A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)
  3. After that, enter the following into Command Prompt and press Enter.:
    • cd /d %windir%\system32
  4. Enter this line in Command Prompt and press Enter:
    • cd /d %windir%\system32
  5. Reregister the BITS files as well as Windows Update files. This step might take a while because there are a lot of commands that you need to enter. Remember to press Enter after each command.
    • regsvr32.exe atl.dll
    • regsvr32.exe urlmon.dll
    • regsvr32.exe mshtml.dll
    • regsvr32.exe shdocvw.dll
    • regsvr32.exe browseui.dll
    • regsvr32.exe jscript.dll

    • regsvr32.exe cryptdlg.dll
    • regsvr32.exe oleaut32.dll
    • regsvr32.exe ole32.dll
    • regsvr32.exe shell32.dll
    • regsvr32.exe initpki.dll
    • regsvr32.exe wuapi.dll

    • regsvr32.exe wups.dll
    • regsvr32.exe wups2.dll
    • regsvr32.exe wuweb.dll
    • regsvr32.exe qmgr.dll
    • regsvr32.exe qmgrprxy.dll
    • regsvr32.exe wucltux.dll
    • regsvr32.exe muweb.dll
    • regsvr32.exe wuwebv.dll
  6. Next try resetting Winsock. To do this, enter:
    • netsh reset winsock
  7. And press Enter to execute the command.
  8. Restart BITS service and Windows Update by entering this into Command Prompt:
    • net start bits
