About 32 bits and 64 bits for Windows

I installed both versions of Notion 4 because I needed to use some 32-bit plugins.
I see that jbridge works well, in a transparent way (since it 'prepares' the plugins in a way similar to truly converting them to 64).
I am thinking about uninstalling N4 32 bits but I'm a little afraid of losing activation (again!) or messing on the 64-bit installation. So I have 2 questions:
1) Will I harm my installation when uninstalling only the 32 bit version of the program? this in Windows 7 32 bits
2) Will having both versions interfere in any way with Notion 64-bit stability or features, such as REWIRE? (very important for me).
Thanks!
