Symptoms:  You may get the error “03513: Please install the Microsoft script debugger.” as shown below when you try to use the Appeon debugger even if you already installed the Microsoft script debugger.

Cause: The Microsoft script debugger was not correctly installed (probably due to limited permissions) and as a result the directory C:\Program Files (x86)\Microsoft Script Debugger does not exist.

Solution 1#: Right-click the Microsoft script debugger installer and then choose Run as administrator to reinstall the Microsoft script debugger.

Solution 2#: If the above solution does not work, please try the following one:

Step 1: Please click Restore advanced settings and Reset as shown below.

Step 2: Please check whether the script debugging is disabled in Internet Explorer. If yes, please go to Internet Options > Advanced in Internet Explorer, de-select the option under Browsing: "Disable script debugging" in Windows 2000 and 2003, or "Disable Script Debugging (Internet Explorer)" in Windows XP.

You may also check the important requirements by referring to the local Appeon Help in Appeon Help > Appeon Developer User Guide > Debugging Appeon Web Applications > Important Requirements or in the Appeon online help to make sure all requirements are met.
