Razer Installer Directory MASSIVE

Was trying to do some basic maintenance and noticed that the C:\\Windows\\Installer\\Razer directory was an INSANE 1.9Gb Mostly full of older installers it doesn't clean up during upgrades.... (attached is a partial list - screen clip). There are a few other razer directories in the Installer subdir - small in size (Central, Manager Service, Synapse) Normally I'd just zap the older versions... but in this case I'm going to both ask if it will create issues and suggest that the simple process of cleaning up the installer directory be done automatically on update (maybe save previous 2 in case one needs to step back So - can I clean up the obviously versioned files??
