I have edit and test the package but now work correctly:
1.If i run it in a S.O microft where there is not install WMP11/12 package not run and i see an error.
2.If there is wmp11/12 installed packege run but:
-i can't select and play (in explorer) more song
-i can't insert the default player for all mp3 open with WMP10
-i can't insert it on a windows bar with command:

regsvr32.exe “%ProgramFiles%\Windows Media Player\wmpband.dll”
regsvr32.exe “%SystemRoot%\System32\wmp.dll” )
How i can create a complete package working on every X64 system?
