[wix-users] WiX fails to launch the installer when previous launch was from a removable drive

[Hoover, Jacob]

The BA should be defending against bad/missing/malformed variables and not just blindly write a log file to a path in a variable.  You are assuming that the path where the installer started was writable, always available, and that you actually have permission to write to it.

That being said, what do the logs in your temp folder show?  When is the failure happening? What does the code near this code look like?

Below is how I am writing to the file from my custom BA class.

               string launchedFolder =
Path.GetDirectoryName(this.Engine.FormatString(this.Engine.StringVariables["OriginalLocation"]));
               File.WriteAllText(launchedFolder + "\\exec_result.txt", "fail=Update failed: " + "Product Already Installed.");

Above variable original location is set in the Bundle.wxs file of the boot strapper as shown below.

              <Variable Name="OriginalLocation" Type="string"
Value="[WixBundleOriginalSource]" bal:Overridable="yes"/>

I tried attaching the device again, before running the install from the local drive. Still getting the same error. Any clues?
