Oh ho !  I am not the only one bogged down with kaput hard drives, runtime re-installs, lost archives, bunged up DVDrom and CDrom backups, etc etc etc.  I commiserate with all folk who have to re-install runtimes.  

I can't say it's a simple administrative task to backup Gigabytes of runtimes, but I do it.  Just that every so often, I need to update the backups as new items get installed.
I would rather be rendering than archiving.
