Error 1603.... Tried everything I can think of.

I tried to reinstall CIS after using all the tools to completely remove it and install a fresh copy.
Now CIS won’t even install at all.

At 99% I get
“Cannot install COMODO Internet Security”
“Error 1603: Fatal error during installation.”

I read it was a locale setting ( so I checked and my Locale is set to English (United States).

What can I do to fix this 1603 error?

Here is a debugview log:

Still need help fixing this please.

Bumping again.

Still having this issue and so are others on the forum!

My locale is set to ENGLISH, so that fix doesn’t work.

I’m on Windows 7, so it’s not an error caused by an incompatible OS.

Why isn’t anyone addressing this?
