Symptom is that the .NET application starts correctly on the majority of PCs (Windows 7 and XP) at the user's site, but on one machine it consistently fails to start with the error "The application failed to initialize properly (0xc0000135)". What's the issue?
This error is caused when the .NET framework is not installed on the target computer, or when the version(s) installed are not sufficient to run the application. The resolution is obvious: install the correct version of the .NET framework before running the application.
