Q: OS X Yosemite installation failed

Hi,

 

On my Mac mini Mid 2010 I have downloaded OS X Yosemite and after installation start I am receiving the error "This copy of the install OS X Yosemite application can't be verified. It may have been corrupted or tampered with during downloading".


OS X 10.9.5 is currently installed on my Mac.


Thanks for any help,
