I have been having this same problem. I copied the file in question from my laptop, to my desktop (which was having the problem) and everything worked fine. Now, about a month later, I'm having the same problem on my laptop, for no conceivable reason!
Nothing Quark Support has told me to do has worked, that bit they give you about running the components installer from "For System" has NEVER worked. It won't install on either my desktop or my laptop, and it never tells me why. Just says an unknown error has prevented the installation from completing. Mind you, my laptop is brand-spankin-new, and isn't cluttered with software.
I think it's terrible that Quark Support obviously doesn't know how to resolve this issue (After a week of exchanging emails with them the problem has yet to be resolved), and the Quark programmers are obviously morons because Quark is not only buggy, but it "breaks" easily.
If any normal person has found a way to really fix this and/or prevent it from happening again, please let me know.
