Here is a nsis program I made at least 7 years ago because there was no silent installer to install the original cdisplay to read comic books:

I think the setup only registers the associations cbr and cbz with windows 7, not under xp. I still use it today though it's years since it has not been updated and it's a little slow today, but for me it's the best comic books reader. If someone has some improvement suggestions, tell me. the silent switch is /S
A new link was added since it was dead.
