Can I change the path for plugins before i launch cubase

ive been trying to solve this one all weekend. i purchased a waves bundle and when i started Cubase it asked me for path, after 10 minutes of trying a few different paths, i decided to yes to the one show, it repeated about 30 times :frowning:

So, now when i try to start Cubase 8.5, when its initializing the plugins, it looks like it tries to load other non music files from my pc, them crashes.I removed all the waves stuff and Cubase. Reloaded Cubase (even in the safe mode) and its still the same.

If I could change or the path that Cubase looks for plugins on my PC before I start Cubase, I think that may work, but I cant find it.
Can anybody help :open_mouth:
