Software Deployment

hello all, I am researching a small issue but I thought I'd see if someone else has already come across this

I have created a package that if I install manually with the command
msiexec /i "name.msi" /l*v "name.log" /norestart /qn
it creates the log file "name.log" with the size of over 6MB and the following at the end
*!*!**!*!*!*!*!*!*!*!*!*!*!*!*!*!*!*!*!*!*

But if I push it through SCCM with the same command, the log file size is about 2MB and has a different ending
*!*!**!*!*!*!*!*!*!*!*!*!*!*!*!*!*!*!*!*!*

The product seems to be installed OK but since I don't know it very well, I'd be more comfortable if the log files were the same

Do you know of a reason why this would happen?

thank you very much
cheers,
