Moving a license to a new device

For desktop licensing:


Licensing of Zoiper for Desktop is done on a per device basis. Moving the license to a different PC or Mac is only allowed in case of hardware failure(for Zoiper3). Since Zoiper5, there is no-longer any limit on the number of resets allowed. This is due to the fact that these are completely different platforms with various operating systems.
