The "Requires specific drive letter" is not a pre-requisite check before installation. It is a program option that maps a specific drive letter to the share on the DP where the package files are. This means that the deployment for the program must be set to runs from DP. This option is not possible for Applications and thus the "Requires specific drive letter" is also not possible.

I need to install an application which requires a specific drive on the client machines. I do not see an option in application model like "Requires specific drive letter" which we have in package model.

Am I not looking at the right places? Please direct me.

Hi Sooraj,

If you want your application only install on computers that have a specific drive letter, you can create a global condition and put it as a requirement to your application (in deployment type properties).

If you want your application to install on D: instead of C: (as an exemple), I think the best way to do that is by modifying the .msi.

Is that answer your question ?

You could perhaps use something like

GET-WMIOBJECT query SELECT * from win32_logicaldisk where DriveType = '3' AND DeviceID = 'E:'

however you'll need some returns and conditions as well in your script. Read more about that here: http://technet.microsoft.com/en-us/library/gg68204

Jason is spot on, switch to using a Package instead of an Application if you require access to the DP files during execution-time via a mapped drive letter.

Agreed! Misread the question.
