Hi Lisa,
sorry it's been a while since you posted your issues and we haven't replied, we apologize for the delay. Something went wrong on our forum system and we haven't been receiving some of the issues.
Unfortunately we can't include the .NET framework in the installer because of its size. You are right, not everybody would know how to go through with it. But we are hoping that most people would have it already installed since Windows XP SP2, Vista and Win7.
Sorry for the confusion this might have caused.
The SharedNote.com website is being upgraded to be a bit more user friendly, we hope we can release the new version soon.
