I would like to reinstall a few machines and found a relevant iso in our company repository, I'd like to know, if it is undamaged and checked the SHA-1 and received "AB2C2D525D63A72E0A2DC66EFDCEA0F824F02CFF" is it authentic/undamaged? (Office 2013 x64 SP1)

Hi,

The SHA1 you received matches the SHA1 hash of Office Professional Plus 2013 with SP1 VL (x64, English).

It's a volume license version of Office 2013 with SP1.
