Some players are having trouble with “This version of Windows is not supported” error, even though they are running Windows 10 or 11.
In this guide, I’ll go over some methods to fix this problem.
Method 1: Check compatibility flags of DivaMegaMix.exe
I don’t know why no one has mentioned this.
Go to your Steam Library, right click on Miku Mega Mix, choose Manage -> Browse local files.
Right click on DivaMegaMix.exe, choose Properties and a dialog will show.
Go to Compatibility tab, make sure that “Run this program in compatibility mode for” is unchecked.
Click on “Change settings for all users”, make sure that “Run this program in compatibility mode for” in the new dialog is unchecked.
Press OK and OK to save configurations and exit.
If you have done this and still facing problems, or the check boxes are not checked at first, then use the following method.
Open Regedit, go to
then for any values related to DivaMegaMix, delete it or remove flags related to Windows versions.
After that, go to
and do the same.
Note that if you have multiple users on your machine, then you’ll need to do this for each user.
Method 2: DLL Hijacking to hook RtlGetVersion
DivaMegaMix.exe uses RtlGetVersion API to retrieve Windows version. It is affected by compatibility flags.
I have written a simple DLL to force it to return Windows 10.
Go here – [github.com] , download userenv.zip then extract it to your Miku Mega Mix game folder.
The code is open source, and the DLL is not packed so you can easily verify that I didn’t include any malware inside the DLL.
Method 3: Patching version check code in DivaMegaMix.exe
This method is well known and there are many guides for it so I’m just mentioning it here.
The disadvantage of this method is you will have to do it again every time the game updates.
Special K also uses this method.
This is my first time writing a guide here, and I hope that it would help the community.
Any questions or advice on how can I improve the guide, please let me know in the comment.
