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=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.
