Run lua io.popen program with spaces in the path

I try to start this program, but always get an error.
I've already tried to make the block quotes [==[]==]around the string and "" around the program path, but it still does not work.

local test = string.format ([==["C:Program Files (x86)Audacityaudacity.exe" "F:Aufnahme %s.%s.%sZOOM0001.WAV"]==]day month Year)

print (test)
io.popen (test)

Error while running the Lua file

If I copy the command from the print (test) and use it in cmd.exe, it works.
