jscript.dll problem.

Topic

New Reply

I have to believe that the jscript.dll is corrupt. I ran sfc /scannow, and the log shows very much at the end that it is unable to repair the file.
I noticed the issue for two reasons:

1) Installing an update to NordVPN stopped the update without any display of an error. However, downloading the whole file and trying to install it ended in a short Windows error box saying an error occurred with jscript for customization. Then, uninstalling NordVPN and then reinstalling established the program again.

2) At startup MS Spotlight does no longer change the picture. Investigating this showed me that the folder C:\Users\myname\Appdata\Local\Packages\Microsoft.Windows.ContentDeliveryManager….\LocalState\Assets\ is empty.

I am not sure whether 2 has something to do with jscript.dll, but it could. In the result log of sfc the following line appears three times:

Cannot repair member file [l:11]’jscript.dll’ of Microsoft-Windows-Scripting-JScript, version 11.0.18362.592,
I waive on the complete line, but the remainder shows the probable folder like AMD64 and nonSxS.
The version of script.dll is  10.0.18362.592

I also ran DISM.exe /Online /Cleanup-Image /RestoreHealth
command from Windows PowerShell (administrator) environment with no result.

I checked the Event viewer and there are no significant Critical Errors in Event viewer, except for this one:
Event ID 10005 MSInstaller with this text: “Product: NordVPN — Error 2739. Could not access JScript run time for custom action .”
I also ran chkdsk c: /r /scan command. No problems found.

The PC runs ok except for the two things mentioned at the beginning. I do not want to rest the PC because of a single file failure. This file is a MS file!!!

Last but not least I tried to register the file again with regsvr32.exe jscript.dll, which ended up in a failure with some error message. I wonder what the real problem maybe. Something is broken somewhere.

I appreciate any advice but NO RESET because I lose all settings and apps and that may take weeks to recover to a status that is ok. To mention this the problem occured about 2 weeks ago.

Please see this blogpost and this blogpost. The bug has been reported and discussed there.

Neither of those deal with jscript being broken.

From both replies above can I conclude, there is no way to rectify the problem, really?

Thank you. However, I was logged in! Not sure what happened.

Hope to get a good reply to solve the jscript.dll issue.

Due to a security problem in jscript, I expect that Patch Tuesday in February will include a newer version.  If you can wait until then, the update may fix things.  The problems so far that you have seen sound minor.  Also, make another full image backup of your computer.

Please, take it that I disagree with the “minor”. Any annoying things that happen and have grown on MS’s ignorance as I call it, are not minor. Ok, I do hope as said here that the next Patch Tuesday will fix the issue. I can wait.

Check the permissions on the file. See my screenshot below.

I gave it Full Control, then used cmd (Admin.) and regsvr32, failed with “The module jscript.dll failed to load.” Followed with a longer text and “Access denied”.

Image backup and reinstall would be my suggestion.

Have no image back up of a time before the issue occured. A complete reinstallation is out of the question. Such an effort is in no relation to the problem.

Windows 10 feature update ISOs can be installed as a repair install.  You must backup first, but the process usually does not destroy any data files or programs (it does change settings back to default).  I am however, not suggesting that you do this.

Is it possible you had used the workaround for the recent IE/jscript vulnerability?
(or even on the previous occasion in September 2019?):

https://www.askwoody.com/2020/yet-another-jscript-vulnerability/

Restrict access to JScript.dll
For 64-bit systems, enter the following command at an administrative command prompt:
takeown /f %windir%\syswow64\jscript.dll
cacls %windir%\syswow64\jscript.dll /E /P everyone:N
takeown /f %windir%\system32\jscript.dll
cacls %windir%\system32\jscript.dll /E /P everyone:N

Impact of Workaround
Please note: Implementing these steps might result in reduced functionality for components or features that rely on jscript.dll.

I think it would be worth trying the undo for that (for both folders, assuming 64-bit system):

How to undo the workaround
For 64-bit systems, enter the following command at an administrative command prompt:
cacls %windir%\system32\jscript.dll /E /R everyone
cacls %windir%\syswow64\jscript.dll /E /R everyone

Correct myself from previous. I never used the workaround or knew about it. So, will not try it!

To inform: the spotlight issue has been resolved. However, I do not know how. I used Powershell last night and and did a few things with ist and all of a sudden the issue was gone. What led to it, no idea!

However, the jscript.dll issue still exist, kind of hidden, since there was no update for NordVPN. Have to wait and see for patch Tuesday, which hopefully resolve that issue too.

With today’s patch Tuesday, it appears that the issue with jscript.dll is gone. I ran sfc /scannow (admin) and it reported no problems as opposed to earlier checks. Checking the CBS.log also did not show any issues. Let’s hope it now resolves updates like in my post no longer will break down. Thanks to all who tried to help.
