No image and only audio in converted files with 12.10.2, how to fix?

Currently, ViWizard M4V Converter for Windows cannot work properly on the version of 12.10.2 and later, this is possibly because it has been protected by a new encryption technology. If you use the current version of ViWizard, the output video might have no image, with only audio tracks. But don't worry, our developers are working hard on it, and we will inform you once it's solved. You can follow our Facebook or Twitter to get the latest update.

Now the solution is to downgrade your app to the lower version such as 12.9.0, and ViWizard will work well on it. You can download it here: 12.9.0. Don't forget to re-download the purchased or rental M4V movies that you want to convert. You will also need to de-authorize and then re-authorize your computer on the old 12.9.0. If it still can't be solved, please feel free to get in touch with us via : support@viwizard.com.

Can't install ViWizard on Mac Mavericks and Mountain Lion

You'll get a Gatekeeper message saying that "ViWizard can't be opened because it is from an unidentified developer" when you try to install ViWizard on Mac OS X 10.8 Mountain Lion or 10.9 Mavericks.

To bypass the Gatekeeper alert and install ViWizard on Mac, simply go to "System Preferences > Security & Privacy > General > Allow applications downloaded from > Anywhere".

Can't load any purchased or rental M4V file with ViWizard

If you can't locate any purchased or rental M4V file in ViWizard drop-down menu by clicking "Add Files" button, please try the following methods:

1 Go to "App > Preferences > Advanced" to check whether the option of "Share Library XML with other applications" is checked or not. If not, please check that option and open ViWizard again.

2If the first method doesn't solve the problem, please directly drag and drop the purchased or rental M4V files to ViWizard to converter.

The program requires registration each time I launch it

You can fix this problem by installing ViWizard for Windows as administrator. To do that, you need to right-click on the setup file and select "Run as administrator". Then enter the administrator's password for your computer and install ViWizard.

App crashes during conversion

The causes of App crash can be varied. It might be used by other programs besides ViWizard, or you may have operated it during conversion.

To solve this problem, please simply close other programs which are lauched in background while you are using ViWizard. If that doesn't fix the problem, please let us know by contacting us at: support@viwizard.com.

Can't load any purchased or rental M4V movies from external drive

If you have a large amount of purchased or rental M4V movies saved in an external drive instead of the default library location, you'll find you couldn't directly load the purchased or rental M4V movies by clicking the "Add Files" button in the program.

To solve this problem, please simply drag and drop the movie files from the external drive to the program. If that doesn't fix the problem, please contact us at: support@viwizard.com.

ViWizard can't find the rental movies when I click "Add Files" button

Sometimes, ViWizard can't find the rental movies when clicking "Add Files" button to add movies. We suggest you should manually drag and drop the rental files to ViWizard instead. And we will optimize our product in future version.

Is it normal to receive "Play" command everytime when I start the conversion?

Yes. It's normal. And you have to accept the "Play" command to run the conversion successfully. ViWizard will send the "Play" command everytime when you start convert any purchased or rental M4V movies to make sure if the computer is authorized to play the movie or not. If the movie can't be played on the computer, ViWizard can't convert the movie as well.

When I try to install the ViWizard for Windows, my anti-virus program detected that it contains virus. What's wrong?

Please just ignore the warning. ViWizard for Windows is a newly released application. We haven't applied the Code Signing Certificates from Microsoft yet. That's why we get the warning. But we are sure the program won't make any damage to your computer.

There is no video in the converted MP4 videos, only audio converted. Why?

Please make sure you can play the original purchased or rental M4V movies on your computer at first. If the original videos can be played fine, please let us know the movie name, file size and the detailed computer information. Contact us at: support@viwizard.com.

Can't add or convert purchased or rental M4V files with ViWizard after upgrading to 12.1

Update: The issue was resolved already. ViWizard for Windows fully supports the latest 12.4 or later now.

Many users have found that after upgrading to the latest release of 12.1, ViWizard for Windows didn't work properly. If you are now facing such a problem, please kindly note that this is because the new 12.1 is made to a full 64-bit application that is not supported by the current version of ViWizard. Our programmers are now working on it and trying to fix the problem ASAP. But before the official solution is available, we suggest you not to install the new 12.1 update if you have not done it yet. But if for any chance you have already upgraded to the new version, please downgrade it to the previous 12.0.1 (32-bit) in order to use ViWizard properly. Please follow this tutorial to find out how to downgrade 12.1 to 12.0.1.

Lose AC3 5.1 surround sound after conversion with ViWizard

Some users may find that after conversion, there's no AC3 5.1 surround sound contained in the converted movies when playback. In fact, the AC3 5.1 audio is retained in the output file, but not all media players could support playing AC3 5.1 sound. That has something to do with AC3 codec authorisation but not with ViWizard. To be more specifically, if you test the original movies with AC3 5.1 audio track, you'll find there's no audio if you select the AC3 5.1 track while playing. In this case, we suggest you try VLC media player or KMPlayer that have been authorized with the AC3 codec. For other media players, you may need to purchase or install specific AC3 5.1 codec in order to play the AC3 audio properly.

If you want to play converted any purchased or rental M4V movies with AC3 5.1 audio in Apple TV, please drop the movie file into Subler and select the AC3 5.1 sound track, then click the option to fix faulty audio fallback.
