Converting .MOV files to .WMV (for free)

I’m working on a video on Premiere Pro (mac) and the client wants a .wmv version. Premiere Pro only exports wmv files when you operate on Windows, so I’m kinda of in a pickle here.
Can someone help me? I’ve been trying to get Flip4Mac, but…can’t find a serial number (lol) i feel frustrated…
Anyway, thank you for any help you can give me!!
Answer #1
Use a converter like any video converter or smart converter? If you have good bandwidth, upload the file to cloudconvert.org and get it from there.
