"iTunes has an invalid signature" when loading version 12.9.2 to my Windows PC desktop. Can't update my PC.
I'm trying to update my PC with the latest version of iTunes - 12.9.2. I get 2 error message. First..."Errors occurred while installing the updates; Choose tools > download only, and try installing manually". I proceed with these instructions, but I get another error message before the iTunes file successfully installs..."iTunes has an invalid signature. The download has been removed." I'm using a Windows based PC using the WIN 10 operating system. I've used iTunes for more than a decade. Never experienced this problem before. My current version of iTunes (on my PC) is 12.9.1.4. Please help. Thank you.
