Installed LMMS as 32bit

Having trouble with LMMS? Ask about it here.
So yeah, I noticed recently that I made an pretty uncool mistake, when I intalled LMMS on my new computer a few months ago (It belongs to the earliest stuff I installed :p). Well, over time I noticed that I have problems with 64bit-vsts. I thought it was no problem because I could easily take the 32bit-version. A few days ago (well, okay, a few weaks, but I'm not home so I only have my laptop with 64bit LMMS right now) I noticed that LMMS was installed as 32bit! I want to change that, because 32bit on 64bit maschine seems to crash more often and 64bit is faster and (probably, I don't really know) uses less resources.

So, my idea was it to just install LMMS 64bit over the 32bit version. Is that ok so? Or shall I do something else? (I'm running windows).
Or shall I do something else?
Yes you should backup your own stuff,for safety, and do a un-install
Download the 1.1.3 x64
https://lmms.io/download/#windows
and install that
Ok, thank you! I will do that when I'm back home. If it's not working I'm gonna ask again or something.
