How can I author a WiX custom action that
- Is always called at the end of an installation, at least if there's an install error
- Copies the current MSI log file from its current local to the user's APPDATA folder
I have this managed custom action code. Not sure how to author its invocation in my Wix script. Should the custom action be scheduled for after InstallFinalize? Can it be scheduled OnExit="error"?
[CustomAction]
public static void CopyLogFile(Session session)
{
const string company = "MyCompany";
const string product = "MyProduct";
try
{
session.Log("CustomAction.CopyLogFile entry");
var msiLogFilePath = session.CustomActionData["LOGFILEPATH"];
if (msiLogFilePath != null)
{
session.Log("CustomAction.CopyLogFile MSI log filename: {0}", msiLogFilePath);
var localAppDataPath = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
var destDirPath = Path.Combine(localAppDataPath, company, product);
var destDir = Directory.CreateDirectory(destDirPath);
session.Log("CustomAction.CopyLogFile Destination directory: {0}", destDir.FullName);
var destFilePath = Path.Combine(destDir.FullName, Path.GetFileName(msiLogFilePath));
File.Copy(msiLogFilePath, destFilePath, true);
session.Log("CustomAction.CopyLogFile Log file copied to: {0}", destFilePath);
}
else
{
session.Log("CustomAction.CopyLogFile File path not found");
}
}
catch (Exception exception)
{
session.Log("CustomAction.CopyLogFile exception {0}", exception);
}
finally
{
if (session != null)
{
session.Log("CustomAction.CopyLogFile exit");
session.Close();
}
}
}
