Incorrect parameter error when using 7-zip from the command line in Windows
I am running the following command:
7z.exe a -t7z -m9=LZMA2 test.7z test.txt
However, I get this error: System error:The parameter is incorrect. The error only occurs if I use the -m9=LZMA2 or -m9=LZMA switches. If I remove it, it works perfectly fine. What am I doing wrong?
I am executing the command from Windows XP, 7 and 2008.

Weird, that's the same version I'm using... If I changeLZMA2to something bogus, likexyz, I get theThe parameter is incorrect.error... And usingLZMAworks too, btw.

Tried it on another machine today and it works there as well (exactly as stated above). Did you download it from here? For reference, the MD5 hash is42badc1d2f03a8b1e4875740d3d49336.

I believe you're misinterpreting the meaning of the -m? switch...-m9=lzma2 doesn't give you better compression than -m0=lzma2, that's the -mx switch.
Try this instead:
7za a -t7z -m0=lzma2 -mx=9 archive.7z files
