How to fix the “We can’t open Skype” error
Most of the users that encountered this issue have reported that the error message was no longer occurring after they reset all Skype settings. This procedure involves killing all Skype processes and renaming the Skype data folder.
Here’s a quick guide on how to do this:
Note: If you’re using the built-in desktop version (not the built-in one included by default with Windows 10) we encourage you to update your Skype version to the latest version. You can download the latest version from this link (here).
- Close Skype completely including the tray bar process.
- Press Ctrl + Shift + Esc to open Task Manager. Inside Task Manager, go to the Processes tab and kill every process related to Skype by selecting it and choosing End Task.
- Once every Skype process has been closed, press Windows key + R to open up a Run dialog box. Then, type “%appdata%” and press Enter to open the AppData folder.
- In the opened folder, locate the Skype folder. Once you see it, right-click on it, choose Rename and change its name to something different (e.g. Skype_old).
Note: This forces Skype to create another folder from scratch.
- Restart your computer and see if you are able to sign in at the next startup.
