Mac Security System Software Was Blocked From Loading Scripting

In our recent post titled macOS 10.13 High Sierra Significantly Improves DisplayLink Performance & Stability we talked about how the latest update to macOS improved behavior when using a DisplayLink product (such as the Plugable UD-ULTCDL docking station). To go with that, we wanted to take a moment to discuss the Gatekeeper security feature introduced back in OS X 10.7 which has gone through some changes in High Sierra that may affect installation of some 3rd party device drivers used in devices from Plugable and other device manufacturers. For Plugable, the issue will only impact our products which don’t have drivers already built-in to macOS, such as our USB Docking Stations, USB Graphics Adapters, and USB Ethernet Adapters. Essentially this issue can affect any extensions not developed by Apple. Thankfully if you encounter this, there’s a simple process to fix. Keep reading for additional information and instructions.

In macOS 10.13 High Sierra, when installing new software and extensions, Gatekeeper now requires users to manually approve any new third-party extension before the computer can load and make use of the extension that was installed. This is important as many devices rely on extensions to function properly, and in some circumstances it can look like the software to power a device was installed but the device still doesn’t work. When this happens, users will see the below message:

If you suspect Gatekeeper is preventing an extension from loading, follow the below steps:

  1. Open System Preferences and navigate to the Security & Privacy section.
  2. In the General tab, look for a message at the bottom of the window stating “System software from developer DEVELOPER NAME was blocked from loading”, like in the screenshot below:
    For Plugable products, the developer listed in the message should be “DisplayLink Corp” for DisplayLink powered products (such as docking stations that do not use Thunderbolt 3 technology) and “WEI LU SU” for Plugable ethernet adapters that use ASIX chipsets (as of the time of writing this, all Plugable USB network adapters use ASIX chipsets).
  3. Click Allow, and from there macOS should now be able to properly load and use the extensions and software that were installed.
  4. Test things out! In some instances, you may need to restart the computer for the extension to properly load. So if it doesn’t work immediately, reboot the computer and the extension should load correctly.

Once an extension from a developer has been allowed, this makes the developer a ‘trusted’ source. Meaning that future extensions that are installed from the same developer should not be prevented by Gatekeeper from loading and should not need to have these steps repeated. However, software and extensions from other developers will encounter this same issue and you will need to follow these same steps.

For additional information on Gatekeeper and the behavior described in this post, check out the below Apple and DisplayLink support documents!

Feel free to share your experiences with High Sierra in the comments below, and if you’re having issues installing driver extensions for any of your Plugable products, please email [email protected] and we’ll be happy to help!

macOS Compatibility

Unfortunately, due to changes in macOS 10.15 Catalina and support for third-party drivers, we are unable to continue support for macOS with our ASIX USB to Ethernet adapters (USB3-E1000, USBC-E1000, USB2-E1000, USB2-E100, USB2-OTGE100). Our USB3-HUB3ME and future USB to Ethernet adapters will use Realtek based chipsets that utilize drivers built into macOS.

Windows Script Host is an administration tool built in every Windows operating system. Its main function is the scripting abilities like batch files. The Windows Script Host error may appear on your Windows 10/8/7 computer due to virus invasion, registry errors, or VBS script file.

This article mainly discusses how to fix Windows Script Host on Windows 10.

Quick Navigation :

What does Windows Script Host do?

Windows Script Host, short for WSH, is actually a Microsoft technology; it is designed for computer administrators to automate and manage some tasks for the client computers (or servers). The scripting abilities which can be comparable to batch files are included in Windows Script Host. One of the most obvious characteristics is: it’s language-independent. That means the host is able to work with different Active Scripting language engines.

All in all, the Windows Script Host provides an environment for the Windows users to execute scripts in different languages which will perform tasks via different object models.

According to users’ feedback, the Windows Script Host error comes up all the time. The people get bothered by this error seriously have written down the actual situation on the internet; they hope to get help from experienced users, and even professionals. For instance:

Now I tried to disable WSH but I couldn't cause in Regedit I don’t have enabled line so I can't set it to 0 as disabled, the thing is that I've read that WSH can be used by hackers or whatever viruses so I want it down. Is there any way or any software to disable it without Regedit where I miss the enabled line?- asked SurFac3 in Tom’s Hardware Forums

Definitely, the Windows Script Host tool in the user’s computer has been damaged somehow. As he said, virus invasion is of the common reasons for Windows Script Host error. Before telling him how to disable Windows Script Host, I’d like to share the popular causes and situations of Windows Script Host issue.

What Causes Windows Script Host Errors

  • Virus or the Malware
  • VBS script file damage
  • Registry errors

3 types of reasons are found to be responsible for Windows Script Host error in Windows 7, Windows 8, and Windows 10.

  • Virus or the Malware: Windows Script Host virus or malware is proved to be the major cause of this error. The virus/malware may attack your system and infect the crucial system files with a malicious code. In this case, you must remove/eliminate the virus completely in time; otherwise, it may delete your valuable files/partitions, and even ruin your system.
  • VBS script file damage: the VBS script refers to the file that contains VBScript or Visual Basic Scripting codes. If the file goes wrong, the Windows Script Host error vbs will appear on your computer at any time.
  • Registry errors: this type of errors usually shows up when you install new programs over the old programs directly. This will result in a slow speed in opening the programs and even a sudden crash in the system. To avoid this, you should uninstall the old ones completely before starting the install of the new program.

FYI: tips on how to recover from the virus:

Situation 2:Can not find script file “C:UsersPublicLibrariesChecks.vbs” (the file location is not fixed).

This type of error happens when the certain script file needed by the system currently has been damaged or lost. In theory, you could recover/repair the needed script file so as to fix the Windows Script Host cannot find script file issue.

Additionally, you may also receive the Can’t find script engine'VBScript' for script error message sometimes.

Situation 3: The system cannot find the file specified.

Similarly, this error occurs when the system fails to find the certain script file (*.vbs).
