Hello, I'm getting weird error with MacMakeUp 195d , when I press CHANGE - pop's up error what says: Can't setup interface: (3):3758096949 !? Anyone know how to fix it? I'm using Windows 7 Ultimate 64 bit

Hi, I suggest reinstall the software. Right click on the .exe file and choose "Run as administrator" to avoid incompatible issue. Meanwhile, you have two ways to manually change it: 1. Control Panel->device Manage->Network Adapter->Adv.->Network Address, put some values in the text box 2. Change the register key value, like link here: http://www.windowsreference.com/networking/how-to-change-mac-address-in-windows-registry/ Regards,Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
