Uninstall of Otter Management installer

[philwaller5269_6322]

Hi

I have twice installed The Otter 'Management' component on two different VM's and twice i have had to revert to a snapshot of the image due to the installer not invoking, i.e. not uninstalling

it prompts for "do you want to delete data in the DB" and then nothing - this is via Add/remove progs

even when running the uninstall routine from the Otter directory - nothing

please advise

The uninstaller found within the traditional installer (i.e. not the Inedo Hub) can be a bit tricky to debug... this is one of the many reasons behind building the Inedo Hub. We will likely only support the Hub next year.

If you're not getting any errors when you run the installer, the easiest way to diagnose the uninstaller is by following the code. It may be a missing registry key, permissions, etc.

You can also use the code to see exactly what needs to be uninstalled, should you need to do it manually.

        public static void Uninstall(UninstallOptions options)
        {
            string servicePath;
            string webPath;
            try
            {
                GetRegistryInfo(out servicePath, out webPath);
            }
            catch
            {
                return;
            }

            string connectionString;
            try
            {

            }
