Hi,

Absolutely Love using the KO Player but recently the Driver Signing Enforcement Policy on windows 10 Anniversary Update (win 10 V.1607) means I have to reboot my PC and disable the Policy Every Time I want to use it.

I have tried all the test mode options and attempted to Disable the Policy Permanantly on WIndows 10, but It is not possible any more.

Can the Developers of the KO Player get this issue looked into as a matter of urgancy please?

We are sorry to hear about it. Could you give screenshot of error message for us that we can help you better? And could you share us CPU, Memory, Graphics card of your device and version of KOPLAYER? We are looking forward to your reply.

Thank you for your support.

Of Course I can :D [/i]

The Error Message is this.

KO Player Error

The only way to solve it is by rebooting to the advanced options menu and disabling Driver enforcement policy - but due to the new updates in windows 10 the Anniversary update it means you have to do this every time you turn on the PC.

ok VT Is enabled on the Motherboard in the BIOS - Antivirus Is irrelevant as I have already tested that issue, this is not the cause of it.
If you actually look at the image that is available in the details given you will see I am running the latest version. and i have tried re-installing with this Error Message

Tried to re-install the KO-PLAYER - and this short video is the result

Thank you for your feedback. We suggest you try to update graphics driver to check and resolve this issue. If it doesn't work, could you give screenshot about VirtualBox of Vbox folder for us? Thanks in advance.

Thank you very much. We suggest you delete both icons in the Virtualbox then uninstall KOPLAYER. And please kindly check if the folder of KOPLAYER has been deleted.

Then download KOPLAYER from our official website then install it.

We are very sorry for this trouble. Thank you for your cooperation.

I have done this and made sure that the folders were completely removed.

This issue is still happening.

The TianTian Support Driver needs to be signed.

Hi, I also encountered this issue.

I was unable to install KoPlayer after the Windows 10 Anniversary update (version 1607).
On the middle of the installation, a pop up window occurs that says that TianTian Driver is not digitally signed driver so Windows Compatibility Assistant blocks it from installing.

I also found this Microsoft blog about driver signing changes in Windows 10 version 1607. I think this changes are affecting the installation of KoPlayer on PCs/Laptops that has a clean install of Windows 10 with the Anniversary Update (just like my laptop since that's what I did).

Additional info:
KoPlayer v1.3.1046
Asus TP301UA
Windows 10 Home, version 1607 (clean install, not upgraded)
Intel(R) Core(TM) i3-6100U CPU @ 2.30GHz 2.30GHz
4GB RAM

I tried installing KoPlayer on my sister's laptop (which was upgraded to the Windows Anniversary Update) and there was no problem. I was able to play Pokémon Go with it.

Hi, I've tried installing the latest Koplayer version 1.4.1049 and it did not install properly.

During the installation, this popup appeared: http://imgur.com/spvkzgM
TianTian Support Driver is block and was not installed.

Although the installation finishes, it was not properly installed.
When opening the KoPlayer application, another popup appears: http://imgur.com/BiXXqJC
It says that "Virtual Machine start-up failed"

I think this issue is because TianTian Support Driver was not installed during the actual installation. I hope this information helps.

NOTE: I got an error when posting or replying or editing so I'm just using the Quick Reply

I forgot to point out that the driver I'm referring to is the TianTian Support Driver, not the installer.
Also, the link from the Microsoft discussion site that you've given is not helpful since I did not encounter those issue when downloading the KoPlayer installer (both the 1.3.xxx and the 1.4.xxx version).

The only issue I have is, that the Program Compatibility Assistant is blocking the installation of TianTian Support Driver. And I think this is related to this Microsoft blog.

Thanks.

Just a note that this issue is still happening with KOPLAYER 1.4.1051 (released 6 days ago). The issue can be temporarily avoided by disabling Secure Boot, but that makes Windows take 2-5* as long to boot up.

The permanent fix will be when KOPLAYER updates to using the latest version of VBOX, which doesn't have this issue anymore.
