deployment: [xxxx]? for directory letter of os


I am preparing a deployment for a program using .net deployment project.

I'm looking at the DefaultLocation property and I imagine that that might be where the product tries to get installed if user runs the setup and accepts all the defaults as they appear...

The question is, there must be some token which refers to the directory in which the operating system is installed.  

For example [ProgramFilesFoler], I believe, refers to
C:\Program Files   (should o.s. be installed on c: drive, as typically is the case)

Is there a token I can use to refer to the root directory in which the operating system is installed.

For example, if xp is installed on C: then
[Root] might give you C:\

(Only I don't know what that token is...  I'm just guessing that it might be Root)


How do I set my DefaultLocation property of the Application Foler to point to   x:\Apps directory, where x refers to the operating system in which program is installed....  Apps already exists as a directory...

I imagine that I might set the Manufacturer to be Apps, but it is trying to install to Apps\ and is thinking that Apps is some network directory location....

According to the windows installer sdk [WindowsVolume] should be what you're looking for. The sdk also states that "the values... are guaranteed to end in a directory separator", so you probably want to use [WindowsVolume]Apps rather than [WindowsVolume]\Apps.

MessageBox.Show(Environment.GetEnvironmentVariable("HOMEDRIVE")) ' The drive where the OS is installed
MessageBox.Show(Environment.GetEnvironmentVariable("WINDIR")) ' The Directory where the OS is installed

infact this will also do the same for you:
MessageBox.Show(Environment.GetEnvironmentVariable("SYSTEMDRIVE")) ' The drive where the OS is installed
MessageBox.Show(Environment.GetEnvironmentVariable("SYSTEMROOT")) ' The Directory where the OS is installed

Desp,  

Nice try, but no cigar...

it doesn't work...  Not in the context of a field property....
You cannot set property to Environment.xxx.xxx..... etc...

There has to be a token which stands for the root directory...
I don't know what that token is...

It has to be something like
[Root]

What we are dealing with is application deployment app.
