I'm sorry if this is off topic, but I too have the problem where Architect 2.2 doesn't start. I just downloaded the evaluation package and installed it and it doesn't do anything.
When I click the desktop icon, it creates the Sencha Architect 2.2 directory in the user directory, but then just silently dies. Is there a special prerequisite that I have to install to get this running?
I tried to submit a ticket or ask this question from the company, but I can only do that if I purchase the product and support, but I can't purchase unless I get a working product....
After installation 2.2 will create an empty Sencha Architect 2.2 directory under users. Since 2.1 launched without problems, I duplicated the contents of 2.1 Architect 2.0 directory, but used the new ion file. Now 2.2 also started without problems.
