Is that some home brown build or using the official build/release?

it is the release build downloaded from your site.

I wondered as the path in the exception message neither matches my local filesystem nor the one on my build server. And noone else ever has reported that. And the components in your callstack are quite old.

Is that reproducible for you?

Probably a Windows 2008 related issue. Who knows.

as a test, i just downloaded the installer and it works fine; just seems a problem with the portable version.

here are all the files in the portable version

More interesting than the file listing would be the contents of your portable_settings.txt. But that contains your encrypted session password, so do not post it here, unless you blanked out these in that file.

However, now I know you're using the portable, I can retry to reproduce that issue with my own settings file.

Try r4640 - that does not crash here at least with the portable_settings.txt you just sent me.
