Skype For Business App Won'T Open Windows 10 Have Reported
Unfortunately, many people using Windows 8 and Windows 10 have reported not being able to launch Skype, and many of the users who can successfully launch the program cannot sign in to it with their Skype credentials.
Not being able to use an application that has become extremely common all across the globe (and for good reason too) can be a pretty significant issue.
The following are some of the most effective solutions that any Windows 810 user who cannot launch or sign in to Skype can use to try and resolve the problem all on their own.
A little background to this issue which is most common in Windows 8 and above is due to the built-in apps, where users are trying to run Skype from the installed app, note that there is a difference between an app and and the desktop version.
Before you proceed with any of these steps, try downloading and installing the desktop version of Skype from here.
This should work, but if you already have the desktop version and it is not opening then proceed with the steps below.
If you dont know whether its a Desktop version or a Windows app based version, then you take a look at the picture below which tells the difference.
Solution 1: Run an SFC scan Corrupt system files can often be the reason why Windows 810 users cannot launch or sign in to Skype.
You see, if a system file that has dealings with Skype or is needed in order for Skype to be able to function properly gets corrupted or damaged, Skype will no longer function like it is supposed to, and issues such as the application not launching or not being able to sign you in can be born.
Thankfully, all versions of the Windows Operating System are equipped with the SFC scan utility a utility specifically designed to search Windows computers for damaged or corrupt system files and either repair any that it finds or replace them with cached versions.
If you cant launch or sign in to Skype, running an SFC scan is an exceptionally good place to start trying to get rid of the problem.
If you dont know how to run an SFC scan, you can simply use this guide to run an SFC scan on a Windows 10 computer.
Solution 2: Try launching and signing in to Skype in Safe Mode Press the Windows Logo key R to open a Run dialog, type msconfig.
Check the box next to Safe boot to enable the option, and then also enable the Network option underneath it.
Click on Apply and then on OK, and click on Restart in the resulting popup to restart your computer in Safe Mode with Networking.
Launch Skype and check to see whether or not it starts up correctly or signs you in successfully.
If the problem still persists, press the Windows Logo key R to open a Run dialog once again, type appdata into the Run dialog and press Enter.
Close the File Explorer to launch Skype to see whether or not the issue you were experiencing has been resolved.
Repeat steps 1 and 2, disable the Safe boot option, click on Apply, click on OK and click on Restart in the resulting popup to restart your computer into normal mode.
Solution 3: Disable uPnP Skype has a feature known as uPnP that is enabled by default on all clients.
Unfortunately, this feature can, in some cases, lead to the client not being able to correctly communicate with Skype servers and sign in to Skype.
Thankfully, though, simply disabling uPnP in such cases is enough to get the job done and resolve the problem.
In the right pane, locate the Enable uPnP option and uncheck the checkbox beside the option to disable uPnP.
