I have a vendor supplied MSI that I am prepping for delivery. This package has no references to using a different drive that I can see. I run the install manually in my VM and in places files in c:\service\dminstall. My VM has only one drive. On a production device that has two drives, it is installing the files to d:\service\dminstall. How do you specify a drive for the file destinations and how can I fix this to place the files on the correct drive?

Product Details - default dir = Service\DMInstall
Here is what is in the directory table:
Directory Directory_Parent DefaultDir Full Directory

I added this row and got an error saying this property is predefined and will be over written during install. Where would the predefined element be?

thats no problem

ok that and add your property

by default windows installer will install on the drive with bigger space regardless of drive letter

if your have 2 drives on your pc say c and d

if d has more space than c then by default your app will install to d

if you have to install appllications to anyother Physical Drive (not network drive) you can do so in the following way.

default INSTALLDIR : C:\Program Files\Dir1
Change to D:\Program Files\Dir1

1. In the MSI Script create a custom action
In "User Interface" just after "Cost Finalize"
"Set Directory" give it a Name , choose the directory by browsing to
ProgramFilesFolder\Dir1 and in the third Blank Space enter "D:\Program Files\Dir1"

2. Create the same Custom action in "Execute Immediate" just after "Cost Finalize" also

This installation works fine as long as D: is a valid Drive, it does not work on drives that were created using "Subst.exe" Command.
