sshfs: invalid argument `create_file_umask=0644'

[hello10293]

Hello,
I can't seem to get the write permissions to be octal to be 0644 when creating new files. I try using this command:

"C:\Program Files\SSHFS-Win\bin\sshfs-win.exe" svc \sshfs.r\user@[REDACTED] N: -o create_file_umask=0644

But for some reason, it gives me this error for some reason:
sshfs: invalid argument `create_file_umask=0644'

I've tried putting the binary in the %PATH%, but it still didn't work
Please help me, I need it to be the right permissions because my website won't work for some reason.
Thanks! ^_^
