.NET Forum / .NET Framework / Setup / April 2005Create a folder off the C:\
The app we are developing uses an older COM component that apparently does not recognize long directory names. So, when we created our Setup project and put the needed files in the TARGETDIR\ourSubFolder, we got runtime errors due to the path being "C:\Program Files\Our Client Name\AppName\ourSubFolder". The spaces were causing a problem. Fine, we thought we'd just create a folder with default location of C:\ourSubFolder & use it. That works, but if for some reason the app gets installed on a machine without a C:\ (D: is root for whatever reason), the install will fail. Is there a property that we can use to pick up the drive letter of the installed app, & piece it together with ourSubFolder name? Something like: [ROOTDIR]\ourSubFolder ? I found a [ROOTDRIVE] element, but it just adds ourSubFolder to the TargetDir, instead. Seems like life is spent coding for the smallest of exceptions. This is my first .Net development effort, by the way. Still trying to learn all the nooks & crannies. Thanks for any input! [SYSTEMDRIVE] is an environment variable that will return you the rootdrive of where Windows is installed.

What sort of syntax is used? In the File System setup, I tried creating a "custom folder" with a DefaultLocation of [SYSTEMDRIVE]. Then the subfolder under that, that I wanted. Installation still created the subfolder off the [TARGETDIR], or app's install path. I then just made a "custom folder" with no sub folders, and set it's DefaultLocation to [SYSTEMDRIVE]\ISISTest. When I run *that* install, I get an error box "Could not access network location \ISISTest." I'm not sure where to use this env var. Thanks! My mistake I though it was possible this way because I have used it several times when I define the path using the /i commando line parameter of the msi. To get the systemdrive in the setup you need [WindowsVolume]\ISISTest Please reply if this still doesn't help you. Gabriel Lozano-Mor?n > What sort of syntax is used?

Hello Steven, What you need to do is to modify the DefaultLocation property of your Application folder to [WindowsVolume]\DesiredFolderName This will make the contents of the application folder go to the destined location as desired by you.

Instead modify the Default Location property of your application folder to [WindowsVolume]\DesiredFolderName. That shoudl achive what you want. Regards Vipul > What sort of syntax is used?
