I have tried several times to install elements 12

Question

Then I found out I was supposed to deactivate prior to uninstall. I don't know how to do that. The program will not run, when I try to run the program my screen goes wonky, and the organizer will not come up/ load, nothing much happening that is good so far.
# 1 How do I ensure proper deactivate/uninstall, where do I go and what do I do?
# 2 if I get that far along, are there any tricks to activating the install, I will be trying this for the 5th time, please advise, I need results.
# 3 happy new year!

Answer 1

Thanks for your reply and your help did allow me to remove Premier from
the computer. The elements 12 never would get up and running  ( so I
couldn't try the log out trick), every time I would try to run the
program (using the desk top icon) the screen would go black and then
come back in a very pixilated and cartoonish fashion (wonky).
The back story is that I had been running Elements 10 for quite some
time, and then I "borrowed" an Elements 12 program to " try it out",
every thing went well for about a week, and then I couldn't get the
program to run, so that's when I decided to uninstall/reinstall it the
first time. Then I thought (perhaps rightly) that Adobe had locked me
out of the Elements 12, so I bought my own new version of it, and
installed that ( with no better luck)
  I am running Windows 7 with an icore5 processor, no error messages,
but in doing a trouble shooting search, the info came back that the
program was incompatible because I had Windows 6.1 and an AMD 64
processor, I don't know what that means to me at this moment. I did a
Regedit scan and found a bunch of stuff related to elements 12 ( I
haven't touched it yet) I did a system restore to a prior date (trying
to get back the the point before all of this stuff happened. I haven't
been brave enough to try installing the program again yet.
