I'm trying to make an administrative install for Office XP. I want to chain the multi-language pack at the installation time and here what i did in the setup.ini: [ChainedInstall_1] Path=1036\lpk.msi TaskType=msi IgnoreReturnValue=0 Reboot=0 At the end of the installation, i get the "msiexec /?" dialogbox... It seem to invoke msiexec with bad parameters or something like that. Also, it works fine on windows 2000, this error is only with XP! Anyone have a clue? Thanks!
