Audio2Face installation failed (Japanese Windows 10)

It seems to be a different issue from the following report, so I will report it anew.

When I try to install Audio2Face(2021.2.3) with Launcher, I get the following error and it fails.


launcher.log :

[2021-04-20 09:01:45.059] [error] (node:10648) UnhandledPromiseRejectionWarning: Error: Command failed: “K:\NVIDIA_omniverse\ov\pkg\audio2face-2021.2.3\pre_install.bat”
10 �̎g����������Ă��܂��B

In “pre_install.bat”,

for /f “tokens=3” %%i in (‘systeminfo ^| findstr “Version” ^| findstr /V “BIOS”’) do set ver=%%i

uses systeminfo, which seems to depend on the OS localization.

Put “chcp 437” at the beginning of “pre_install.bat” and this process was successful.
“chcp 437” is a command to force the language to English.

I’m still trying to install manually.

Hi @ft-lab , thank you for your interest of Audio2Face. That error means the Windows version you have is not supported. If you go to start menu and type “winver” you should see what version of windows you have.

Audio2Face support windows version 1909 and above. Once you update your windows version to this or higher, you should be fine. Thanks.

Thank you for your reply.
I’m using OS version 20H2(build.19042.928), which is the most recent version so far, but Audio2Face seems to fail to install.

I see, I think you are right in the language part and whether our check is good for your version of windows. This is great feedback, let me talk to the team and get back to you.

I have the same issue as ft-lab mentioned.
I am using Korean Windows(with latest build) and same message.

according to what I made to run Audio2Face, adding the line “chcp 437” the top line in “audio2face.kit.bat” and “pre_install.bat”, his comment “uses systeminfo, which seems to depend on the OS localization.” looks understandable.

however in this way, I can’t see any icon or launch button in Omniverse app.

I hope this will help the issue

@yuha8486 thank you for your post, your comments are definitely helpful and these are great feedback for us to know. Not being able to see the icon or launch button with this method is good to know. Can you post a screenshot also so we can see what it looks like? Thanks

@siyuen sure please look at the file I attached.
I am Running a2f, still no icons on library category in omniverse app

hope this will help. Thanks

Thank you for confirming the installation of Audio2Face.
I was a little unsure if it was just a problem with my environment, so this was helpful.

I’ll wait for the Audio2Face installer to support it.

I have the version of windows 10 20H2 and I have the same error.

Hi Everyone! I’ve created an internal ticket (for your reference OM-30499) and sent it in to the development team. Thanks for your patience as we work to resolve this issue.



The same error:
Error occurred during installation of Audio2Face: Command failed: “C:\Users\Mixxx\AppData\Local\ov\pkg\audio2face-2021.2.3\pre_install.bat” “10” kann syntaktisch an dieser Stelle nicht verarbeitet werden.

Windows 10 Pro for Workstation 20H2 (Build 19042.804) German.

Thanks for the post and info. It is the same issue and we will have a patch to fix this soon. Stay tuned. Will post update here as the patch is released.

Hi @ft-lab @yuha8486 A new version of A2F has been released and is available on the launcher. This version should work for all regions. Let us know how you get on.


Thanks for the fix!
I have confirmed installation and run with Audio2Face 2021.2.4 on Japanese Windows 10.


I successfully installed A2F

Thank you all
