I want to know how can i change or rather the computer changes the disk cost in case of a per user or a per machine install.
I have an installer that is approximate 50 MB in size when i check in the program files how ever when i am using the DiskCostDlg it shows me 96 MB , i am doing a per user and a per machine install and i am surprised to see that in both the cases the disk requirement is same.
I need to know if there is a possibility of changing the disk requirements or is it a default property of the Wix Installer.
Thanks
Windows Installer needs extra space for the installation process. This is why it shows more than your total files size. Here is an article with more details: http://blogs.msdn.com/b/heaths/archive/2008/07/24/why-windows-installer-may-require-so-much-disk-space.aspx

Per-user or per-machine refers to the install location, they have nothing to do with file size. The installed files are the same and they have the same size for any location.

It cannot be changed because it's calculated automatically by Windows Installer.
