Hi there, I am facing a problem whenever I launch mesh. It says Scrip Error (type mismatch 800a000d). I recently updated my laptop to Windows 11 version 24H2, maybe that might be the reason. My geometry imports perfectly fine in design modeler but in mesh this error pops up. 

Please please help me to resolve this issue. Thank You!

Yah I have the same issue have you found out a way to fix it?

.

Yes, as of now Windows 11 24H2 update is not supported by Ansys. So I fixed the Scrip Error Type Mismatch 800a000d issue by reinstallig 23H2 update on my computer.

To do so open SETTINGS in your PC/laptop then go to SYSTEM then scroll down to RECOVERY. Here you have to choose GO BACK option. Your device will go back to 23H2 version. It will take roughly 30 to 45 minutes. And dont worry non of your files or any data will be lost. Then you can use Ansys as normal. Based on what I’ve read, in Jan 2025 24H2 will be supported…so maybe pause your updates till the time, as Windows will automatically update outside active hours. 

Thank You!!!

Hi, 

 

I don't have the option Go back available, what can I do? it is urgent

[Rajeshwari Jadhav]

Hi Isaac,

Yes, there is some issue with latest windows 11 update 24H2.

Settings> System> Recovery> Go back, The Go Back method will only work if you downgrade to windows 10 within the 10 days of your upgrade (No Data Loss).

When Go back option is grayed out, you have other options to rollback to windows 10 bit you might need to do some research on it or if this is your academic system then you can contact your IT they will help you (Data will be lost).

May I know which Ansys application you are using, if we have any alternate we can share it?

Hi, sorry for the late reply. My laptop is new, so I can't Go back to win10. 

I am using Fluent. For now I am opening everything separetly Spaceclaim → Fluent meshing → Fluent Solver → post. 

I don't really like it this way but I have a thesis to deliver soon.

Ansys Workbench Mechanical and related applications produce JavaScript Runtime Error Type Mismatch on Windows 11 24H2 

Q: Ansys Workbench Mechanical and related applications produce JavaScript Runtime Error Type Mismatch on Windows 11 24H2 
Issue often occurs when importing geometry into a new analysis. Error may be similar to the following:

Script Error 
Line: 61871
Char: 8
Error: Type mismatch
Code: 800a000d
Source: JavaScript runtime error
Script: g_UIHandler.TreeHandler.RemoveAndFillChildNodes(parentNode); 

 

A:  Windows 11 24H2 has begun setting a local policy that, by default, causes applications to use the JScript9Legacy.dll instead of JScript.dll. 

Windows 11 24H2 was not available at the time of Ansys 2025R1 release testing and is not officially supported. 
A future Ansys 2025R1 Service Pack 2 will address this issue without having to modify the Windows registry as stated here. 

This issue can be resolved for all previous Ansys versions by changing the default registry key to load the classic jscript.dll instead of the JScript replacement DLL jscript9legacy.dll.  The end user should understand any potential risks this may cause. 

Search the internet for “JScriptReplacement” or "JScript9Legacy.dll for further information. 

To load jscript.dll by default:
 

1. Launch regedit.
2. Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Internet Explorer\Main 
   (Create the folder Keys for Internet Explorer and Main if they do not exist)
3. Right-click the Main key and select New | DWORD (32-bit) Value.
4. Name the new value JScriptReplacement.
5. Set the value of JScriptReplacement to 0.
6. Reboot the computer
