Dumb question, but should I be ok if i installed RVGL in the same folder as RV1.2
edit: or should have I installed befroe installing RV1.2?
I'd suggest having two separate folders, although they both work if are in the same folder. However, some odd things might happen, mainly with rvgl_dc_pack.7z if is installed and v1.2 is running.
RVGL is more recent than v1.2, so it's better to have the latter one installed first.
