Sounds to me like you are asking a more specific (and different) question than "How do I uninstall Slickedit".
If you were really only wanting to uninstall, you wouldn't have any hotfixes to apply (or be trying to apply them).
You could have leftover vtg, vpj, vpw files, of course, but these should be easy to find as they will be in your project directories.
Please explain more clearly what you are really trying to do. SE support provided an answer if all you are trying to do is uninstall (and not uninstall/reinstall in an attempt to fix some issue that you have not explained).
BTW - if you really do have a more specific question about an issue you are having, you should post it as a new topic instead of in this FAQ topic. If you really just want to uninstall SE, I think the instructions given by SE support are pretty clear.
