Create spark msi with AppDeploy Repackager

Someone here could help me.

About the process of create the msi spark with AppDeploy Repackager.

Before the first snapshot of appdelpoy repackager the operating system I have to use must be clean and of the same type of my local work. Example. If I use in my work windows 7 professional portuguese. I have to use an windows 7 professional O.S. clean and in portuguese. ok ?

During the process of creating the spark msi I use all the options default. ok ?

Some comments about this process it will be welcome.

Thanks in Advanced
