Hi, I’m using Trend Micro Maximum Security, and I have just tried to install on a 3rd PC but failed — got a Too Many Installations window. I’m pretty sure I only have 2 PCs running your software and that I can use up to 3 computers. What do I do now? It’s asking me to enter a password.
Thanks for contacting. To help other customers find this post easier on the internet, I have updated your post title. Hope you don't mind.
I understand that you tried installing on a 3rd PC and the "Too Many Installations" message was displayed. I'm afraid this means that all 3 seats for your license have been taken. It's possible that you have another PC that has Maximum Security installed.
