Issues when installing adobe programs.Need help.

This is happening several times already.
When I install photoshop for example and illustrator is already installed on my machine, after installation photoshop works but illustrator gets unactivated somehow, and it’s asking me to purchase or prolong trial.
Same happens vice versa-photoshop already installed-installing illustrator, photoshop gets unactivated.
Anyone know whats wrong?
Is is something about the registry files, how to avoid it.
How to fix this and install other adobe programs without running into issues.
Answer #1
You have the host file patched I assume ? I’ve always found that effective in preventing it from “calling home” and invalidating the activation . Perhaps you missed out on a few entries that need to be in there . Maybe you could code/paste a copy of your hosts file . Found at system32/driver/etc/hosts (no extension) but will open with a text editor .
