Strange things happens some times.

// This code was added by Steve. It doesn't do anything, but if we remove it, program crashes. No one knows why. Please do not remove the following code.

I'll add this try ... catch in the distribution.

I suppose that if you press Ctrl + I (reload indicators) it will crash because the try...catch covers startup loading only.

I think we can close the case for now due to missing evidences.

with debugging code:

try
{
    CustomIndicators.LoadCustomIndicators();
}
catch(Exception e)
{
    string msg = e.Message;
    if(e.InnerException != null && e.InnerException.Message != "")
        msg += Environment.NewLine + e.InnerException.Message;
    
    MessageBox.Show(msg, "CustomIndicators.LoadCustomIndicators();", 
                    MessageBoxButtons.OK, 
                    MessageBoxIcon.Error);
}

What I can do right now is run FSB directly (not the launcher) compiled using the Debug target, so I'm able to actually use the application now.  I know that doesn't help you narrow down what went wrong ... perhaps a full recursive diff of the sourcecode between 2.93 and 2.98 might be useful?  Or alternately, progressing with development and hope my case is an isolated incident that won't happen elsewhere.

Running a release version built from source crashes too.

Can you run "Windows Remote Assistance", save invitation file and send me it via PM together with the password?

EDIT
Opss no attachments to PM. You can send me the file via email.

If I change the project to run Forex Strategy Builder directly instead of the Launcher, it runs without crashing, and builds the libraries in the process.  Running the distributed FSB in this way results in an immediate crash.  Running a release version built from source crashes too.  Unfortunately it seems I'm not getting much closer here.

System.InvalidOperationException this is the error, but it doesn't help much!?

Edit: After the magic reboot it installs.  I start Sharp Develop...

I think you have to download FSB source code from GitHub and to compile it in SharpDevelop.
It will complain about Processor type 64, but it can be change in project settings.
Probably I'll have to take a look vie Windows Remote Assistance.

I'm installing now virtual machine to test FSB on Win XP with pure .NET 2.0.
This work takes great amount of time.

I'll try to compile FSB on .NET 2 but if it shows too much errors I'll announce a requirement for .NET 4 Client Profile for FSB and FST.
