comodo downloader folder

what is the comodo downloader folder for? It is in the program data folder and contains:
CIS setup.msi and lpcsetup 3.0.131721.7.msi
do i still need setup files or is it ok to delete?

The online installer does not install the software itself. It simply downloads the program installers for you, then starts these installers.
I would move the installers somewhere else (as they are now offline stand-alone installers) if you wish to remove this folder. Personally, I am keeping the folder and it’s contents in case I need them again.
