Re: The issue you have with SketchPath "Failed to Initialize Application..."
Its hard to be certain without further detail, but the issue you're experiencing is most likely related to security permissions of the logon account you are using. SketchPath is a .NET 2.0 application requiring "Full Trust" ClickOnce permissions.
I'm the developer of SketchPath, so if you need any further help please contact me at [email protected]
Finally, I'm bound to recommend SketchPath, but each tool recommended here will have its own strengths, so the choice will be down to your specific needs and constraints.
