Then do it in a bootstrap program. Use the SDK examples for MsiGetFeatureCost that open the MSI file and do the costing and get the feature costs, then launch the MSI with a command line that sets the TARGETDIR property to a destination disk with enough space. That's actually quite straightforward.
The difficulty with making the decision during the MSI install is that you don't know feature cost until you've done costing, and costing includes calculation of what files might be overwritten, and that's why MsiGetFeatureCost wants you to do InstallValidate to get an accurate number - the destinations have already been chosen. I believe that the numbers in the feature dialogs are informational, and it's not until you (say) click Next that the real cost can be calculated. I don't believe that there's a way to do costing and then change your destination disk and do it all over again, although I really don't know how the CostInitialize/CostFinalize/InstallValidate voodoo works and how it ties into the feature tree.

See in CustomSetup Dialog, you will find one message as "This feature requires 200MB on your hard drive" Now for silent install functionality i want this number(200MB) to compare the space. For example: My C drive has actual disk space 100MB and D drive has space 2GB According to my silent install functionality, reqdiskspace is 200 MB, but C drive has only 100 MB So with my functionality, the installer automatically select next avilable drive(here D drive). if(reqdiskspace>actualdiskspace) go for next drive Presently reqdiskspace I hardcoded as 200MB(what ever the number is there in message "This feature requires....") But in future of my feature size increases to 300 MB, then again I have to modify manually "int reqdiskspace=300" So to avoid this, I want the number in that message. So i will get this number through MSIGETPROPERTY in my C++ DLL and I can use. SaiTeja wrote: > > > > Wilson, Phil wrote: >> >> Generally speaking you don't need to do this.
