My Vue 9 xStream installs (Vue 9 32 and 64 bit) got into a confused state so I uninstalled both and reinstalled just the 64 bit.

 

However, it's in exactly the same state as before, even down to what collection branches were open last time I used it. Some collections seem to be empty, some point to the 32 bit install (which now doesn't exist).

 

How can I purge my system of all Vue info so that I can reinstall a fresh Vue install as though it were the first time I ever installed it? All I want at this stage is a basic default install with all the default collections etc, however I cannot lose the previous install hangover.

 

I tried manually deleting all folders & reg entries, and also used a Windows cleaner called CCleaner (the install program wouldn't even run until after I used this).
