Hi. I just installed an SSD Samsung Evo 840 on mid 2012 Macbook Pro with El Capitain. I have Komplete 8 Ultimate software and tried to install it on my Macbook, but I keep getting an error message saying there is no software to be found to install. I removed the usb drive and plugged it into my iMac 2010 upgraded also to El Capitain and it works just fine. I'm a musician and will need my Macbook on Wednesday so any help would be greatly appreciated.
