Can I uninstall an old Beta without affecting my installation of Scrivener 1.9?

My Windows list of installed programs shows two versions of the Beta. They were installed into a different folder than the recommended default.

Can I unistall these without messing up my installation of 1.9, that I am still using for live projects?

All of them should be in different locations, anyway. I removed beta from my Windows machine and had no issues with the remaining Scrivener 1.9. Although you might need to add back its shortcut to appear in Windows menu ( in case it is not there right now).
