As far as I know there must be an antivirus service On in the machine . Try to disable it and then uninstall Appium Studio.

Please try my suggestion. Its possible that the antivirus service was not ON when you are installing.

Sorry that my suggestion did not work. AV is the common symptoms for such problem . Another thing I suggest is to make sure that there are no JAVA related options in System/User variables (_JAVA_OPTIONS

_IBM_JAVA_OPTIONS

_JAVA_TOOLS_OPTIONS

) of u are operating system when you start the uninstaller.
