Sansa Clip+ Firmware Update 01.02.18

I’m trying to install the update on my clip. The updater tells me same ase OLEDCRT. I tried the manual download.

I clicked on it & it wanted to extract w/winzip. They’re telling me it’s not free anymore. I tried downloading 7 zip (c-net says it’s great & can open all zip files).

It extracted it into my vlc program & msg says that’s not an option w/that program.

Is there some way I can extract this file w/o having to purchase winzip
