Hi I'm planning to distribute apps via GPO under WS2003 domain. As you know, this method needs that the app is packaged in a .msi file. Many apps are not. So I needed to package "legacy" apps into the .msi format. I tried WinINSTALL LE 2003, AdminStudio and EMCO MSI Package Builder with no success on SOME apps: the ones that needs a serial number to function. All the config concerning the GPO and the domain is OK, so I'm testing directly on some vms and I can't make it work. For example, AVG Free (that comes with a serial number) has this problem, all the install goes OK, but when it starts for the first time, the apps shows an error message saying that the serial is not valid (in fact there is no serial at all). I have searched a lot but I still can't find the solution. I tried using the ALLUSERS property 1 and 2, install per machine.. and nothing. Thank you in advance Germán
