I have to separate work contacts and family in skype, so I need two Skype instances on my PC.
Here is how you can do. Once you install you will get a skype shortcut on your desktop. Now do the following to create another instance of skype.
Step1: Copy skype shortcut and paste again on desktop. This will create another shortcut.
Step2: Rename new shortcut to your choice. I have renamed it to Skype II
Step3: Now go to properties of Skype II short cut that was created recently and update
Step 4: Update Target path like below from
"C:\Program Files (x86)\Skype\Phone\Skype.exe"
to
"C:\Program Files (x86)\Skype\Phone\Skype.exe" /secondary
Now apply and click Ok.
This should work now. I have tested this on Windows 7, 8 and 10
