It's been like 4 hours but my laptop is not yet done installing the 3.50. I recently upgraded my 2.8 version into 3.50 and seems like it is stuck with installing the Microsoft Windows Mobile Device Center 6.1. Is there anyone who has problem like this? Or how would I cancel the installation, and redo it? I tried restarting and shutting down but it just continue my installation. It's frustrating, please help. Thanks!
