Hi James,
You would need the latest version of i1Match from X-Rite. That is 3.6.2 - here’s a link:

This message that says the software is corrupt - that is a strange one. We don’t normally get that. All I could suggest is to download it again, and the next time should not be corrupted. Lots of people have been using this download since the introduction of Win 7 without any problems.
The reference to digital signature, etc. is a common warning that Microsoft presents to you with a lot of software installs. It’s common and not an issue to be concerned about as long as you are downloading your software from reputable sites. You should be able click okay and continue installing the software. This would have nothing to do with the corruption you mentioned above.
