Running this way muscle would try to save seqs.afa to c:\Program Files \ muscle> folder. On Windows, if you run muscle not as administrator, you may have not permission of writing to c:\Program Files \ muscle>, hence the error.

You can try copying the seqs.fa to Desktop. Then navigate to Desktop in command prompt and execute muscle this way:

c:\Users\you\Desktop> c:\Program Files \ muscle\muscle3.8.31_i86win32.exe -in seqs.fa -out seqs.afa

Note the full path to muscle. If it works you can modify PATH environmental variable (check google how to do it for your windows version) so you could write just muscle\muscle3.8.31_i86win32.exe in the command prompt.
