Just downloaded the trial. I double click on setup, and get the error that Setup was unable to create the (temp) directory it needs in \appdata\local\temp\ It also says "Error 5: Access is denied."
Be sure to not have some antivirus interfering with the program. The setup is standard so all has to work without problems. Be sure also to give the setup administrative rights.
Installing as Admin. Windows Firewall off for the install. I have installed many, many other programs using Windows Installer successfully... Also tried with version 59. Same issue. I am not even seeing the first dialog box in the Install.
I have been using Coffee Cup HTML Editor...but really wanted to find something a little easier to use visually.
