Can I delete the folder "installer" (1 Viewer)

[joEhSuper]

Hi!
My laptop doesn't have much free space anymore, so im trying to find files and folders I can delete without cashing MP (or my system )

In
C:\ProgramData\Team MediaPortal\MediaPortal\Installer\
I found an Folder "V2" wich contains about 5,5 GB of Data. To me it seems that it contailn files from former MP installations

Does anybody know if I can delete this folder (and other folders in "Installer" --> <Backup Settings>, <TVWishLIst>) withour causing problems?

Folder V2 contains 89 folders....
do I need (all?) these folders and files?
