App installers and Validation

[Sg335man]

Hello, I am trying to install a .pkg file from a installer. It does it’s thing but just before the very end a “Validation error failed to verify, contact the software vendor etc.” I have tried to install via the System/Library/CoreServices Installer.app Does the same thing? The Gatekeeper is set to except All, in System Prefs. Any thoughts or ideas would be well appreciated thanks DH
Oh and I have contacted the Software Vendor......

Apple continues to tighten up security, so un-validated apps will not install.
If you contacted the vendor, what did they tell you?

Did you download the same installer again? Best place to download is from the vendor, and not from a download site.

Can you tell us what app you are trying to install? Someone here may have recent experiences with the same install.

I do not complain.
Check around in this forum how many people report having coin mining (or other adware) software on their computers. Seems that these installations of "crapware" are from some unauthorized, modified, and unsigned installers. Like Flash. Someone adds his "crapware" payload to Flash and it gets installed (with admin privileges!) when they successfully persuade you to "update" your "old" Flash version with their "new and improved" one. happens all the time now...

Signing installers is critically important step to prevent this from happening. Let's be happy that it is getting more and more difficult to compromise our systems by using these modified installers...

Depends. How old an installer is, what OS versions it originally targeted.

Mac is not Windows where old stuff is guaranteed to install/run. Sure, there are lots of old programs that are still running today (I've got a couple of these), but with changes in the OS re: libraries, Gate Keeper, SIP, System Extensions (going forward), etc., that old installer just might not be up to the task of dealing with the changes that has occurred over the years.
