Causes of rtfSetNotPermitted - Error 387
ActiveX errors can occur for many reasons. You might experience issues if your operating system settings have not been properly configured. Default values may have been changed in the Windows registry, which in turn, cause certain programs to crash or run incorrectly. As a result, errors may come up when you then run a system check or Windows registry repair.
Errors can also occur due to access rights. For example, you may be browsing the internet and you keep getting requests for installing the latest version of Flash. However, when you update it, it still tells you the same thing. This could be because your registry is damaged or your permission settings are incorrect.
Another cause of ActiveX errors can be due to the use of an incompatible software or ActiveX version, which differs from one third party provider to another. For example, one software provider may require you to use an earlier version and another might need the latest version to fully enable their content to run on your system. So, when you install a version that is different from the one that your applications are compatible with, you will receive a notification that your ActiveX is not working properly because you need a different plugin.
There are other instances when you may be prompted to check your system or your ActiveX because a driver is missing. This could have been caused by the removal of certain shared drivers when you uninstalled another program and your original program needs them to run.
Whatever the case may be, there are several ways to solve ActiveX problems so that your computer continues to serve its purpose.

- Try disabling plugins that you suspect are causing the conflict.
- You can try disabling them one at a time to see if you still get the error.
- Reinstall ActiveX Control and check again if you still get the error when you use your plugins one by one.
- If you are experiencing a problem that is related to a certain program, you can try uninstalling and then reinstalling that program, then check if the problem persists.
- Download and install SubInACL.msi from Microsoft download center. http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=23510
- Download and install the plugin you have been trying to install
ActiveX can pose a security risk especially if you installed a program that is not signed or validated. Google Chrome has strict settings for disallowing plugins that seem to be a security threat.
If you happen to receive a message telling you that the plugin was stopped because your browser security settings disallow it, you should check if its a virus infection before you attempting to reinstall it. If your investigation shows that you are experiencing an access problem, then you can try lowering your security settings and installing the plugin again.
You might also be having a problem with Windows Defender. If that is the case, open your security center and lower the security settings.
