You may be having an issue with K1's write-protection.. although this seems quite different to me, I thought I'd mention it.
Do you have a DVD burner on your system? K1 doesn't like them. I have had difficulties with installation due to this, and been able to resolve it here (

This may or may not lead to a difficulty in removal/reinstallation. I have not had that issue, but every PC is unique :(
BTW.... this is not the place for this type of complaint... I believe you're looking for the "Workbench" or something like that
