Can't install HAXM on WIndows 8.1 Pro

[Wojciech_F_]

Hello.

I'm trying to install HAXM on Windows 8.1 Pro and every time I get the message "This computer meets the requirements for HAXM, but Intel Virtualization Technology (VT-x) is not turned on.". I have a ASUS K75JV notebook with Intel Core i7 3610QM processor and 8GB RAM.

I have tried all found solutions and it still won't install:

• I have the latest BIOS for my notebook
• VT-x and VT-d are turned on in BIOS
• I don't have Hyper-V installed on my system
• I've tried "bcdedit /set nx AlwaysOn" and reboot
• Tried HAXM 1.0.6 and 1.0.7 (Win 8.1 hotfix)

It seems that DriverPackageInstallW function returned true(success).In one or two previous cases of failed instalation driver installing function returned false.Unfortunately there is still message which says that VT-x is not turned on.

Oh! Hi ;)

I'm going to write in this topic, because I have exactly the same problem... And I also have tried the same solutions as Wojciech ;) What's more after using this command with bcdedit /set nx AlwaysOn I had problems with NVIDIA card I think... Because I couldn't start a game with this card. So I used this command: bcdedit /set nx OptIn and now is everything like before. But I still can't install HAXM...

I have Lenovo Z580 with Intel Core i5-3210M and 8GB RAM and also Windows 8.1 Pro. In attachment I send you my install log.

It looks bcdedit /set nx AlwaysOn does not have any effect on some systems.I think that it could be BIOS dependent issue.

[Przemysław_F_]

But as I know I have the newest version of BIOS... Any ideas how to resolve this problem?

[Bernard]

I think that HAXM developers could shed more light on those issues.

So I see we can't count on your help? Any right solutions? I think its bad because our hardware isn't so old and it should works fine... Eh :(

Let me ask around with the HAXM support team, and see if I can get someone to look at this, and hopefully find you an answer.

[Joshua_B_Intel]

I contacted the HAXM support team, and they suggested the following.

Download CrystalCPUID to your system and run it. Check in the bottom right corner of the results screen, and let us know if you see "VT" enabled there, or if it's greyed out, like this:

Let me know what you see there. Thanks!

[Przemysław_F_]

Thanks for help :)

Below screen of this program to give you/them more info ;)

Hello.

Thanks for your interest in this subject. Here's my info, the VT and NX are on...

Hi

I wish I could help you to solve this problem.

[Bernard]

I wonder if ISDM contains any info about VT technology and how to access it(register mappings etc...)

[Joshua_B_Intel]

Thanks to both of you for the CrystalCPUID results. It does appear that VT is enabled on your systems. I've shared them with the HAXM support team, pointing out that you're reporting this issue on Windows 8.1 Pro (and that HAXM has worked previously on this machine under Windows 7), and asking them to look in that direction. I'll let you know what I hear from them (it will probably be next week before we get a response). Thanks for your patience while we get this figured out. 

[Joshua_B_Intel]

For reference (and anyone else who might happen across this thread in the future), here's a page with more detailed hardware requirements for HAXM, and some troubleshooting steps for making sure VT and XD are supported and enabled. 

Installation Instructions for Intel® Hardware Accelerated Execution Manager - Microsoft Windows

It may not be directly applicable to the issue you're reporting, but it would be good to check.

[Przemysław_F_]

In my case I have no idea if HAXM worked on previous versions of Windows... I didn't need to install this then ;)

[Joshua_B_Intel]

From the support team:

Check to see if Client Hyper-V is enabled - it's required for HAXM. 

To check, go to Control Panel -> Programs and Features -> Turn Windows features on or off

See this video for a demonstration. Let me know what you find.

It is disabled. But I read something different... That when it is enabled HAXM is not going to install. However if support team says that it should be enabled I will test it and give you an information in the afternoon :)

[Wojciech_F_]

With Hyper-V installed the HAXM installer doesn't even start...

[Bernard]

It is hard to troubleshoot if only relying on log file.
