The computer tested here uses a 64-bit operating system, so Skype is located in the Program Files folder (x86).
C: Program FilesSkypePhoneSkype.exe / secondary
C: Program Files (x86) SkypePhoneSkype.exe / secondary
Then, click Ok to execute the command. Just like that, you can chat multiple Skype nick on the same computer already. I am currently testing this way and can log in to 6 Skype accounts at the same time on my computer, what about you? Wished everyone success!
