When I start the installer, it complains that lyx is already installed, and that I should remove it first. However, since I don't have admin rights, I can't do that.
But this means that LyX was once installed with admin permissions. There is no other way to uninstall it without admin privileges in this case.
If LyX was installed without admin permissions you can also uninstall without them.
Is there any file that I can remove such that the installer let me install again?
No because as in your case LyX was installed as admin, the registry settings are in HKLM and they cannot be modified by normal users.
