It's done!
Things to change in the msi:
open msi with orca
in the [CustomAction] table add a new row with values:
Action: innoROTA
Type: 34
Source: innoSource
Target: [SourceDir]\program files\rise_dvd5.exe /silent
(@mondragon: don't use /verysilent because its a long process to install all the files and the user may thing the installer hang up and it will try to shutdown the application. Also I send it to the "program files" folder so you keep the install folder clean

)
in the [Directory] table add a new row with values:
Directory: InnoSource
DefaultDir: SourceDir
in the [InstallExecuteSequence] table add a new row with values:
Action: innoROTA
Sequence: 6601 (this will be executed prior to "removing backup files")
the diference between this one and the PES2009 is:
PES2009 runs everything from the install folder (Type: 50 in [CustomAction]) and this one runs from the temp folder (so we must tell the msi to install from the SourceDir = Type: 34)
Installs OK
Uninstalls OK
Merry Xmas!
