Got "Sorry, this application cannot run under a Virtual Machine"

Avast Free Antivirus / Premium Security
1

Yesterday I updated to Avast! Free Anti-virus 8, but today when I tried to run some 3-d games(NBA 2k13 & NFS17), I got a “Sorry, this application cannot run under a Virtual Machine” error.
What can I do with this? :frowning:
Thank you!

Hi, please check version of your \Windows\System32\drivers\aswVmm.sys file.
If the version is later than 8.0.1482.45, then just restart your machine and it should be OK.
If the version is 8.0.1482.45 then execute patch:
http://files.avast.com/files/emupdate/20130304.exe
as administrator. It will replace your aswVmm.sys with version 8.0.1482.47. Then restart computer.

This Patch Does Nothing at all.
(I have the same problem)

Bonjour,

We are meeting the same problem:
after updating to avast 8, we can’t run Virtual PC on a machine under Win 7 Pro, because Avast 8 deny Hardware-Assisted Virtualization.

At this time, replacing aswVmm is not the solution.

After having tested the machine w Microsoft havdetectiontool.exe when avast 8 running, result is :
“this computer does not have hardware-assisted virtualization”

Testing the machine after having uninstalled Avast 8, result is:
“Hardware-assisted virtualizatiuon is enabled on this computer”.

So, how and when would we be able to run VPC w Avast 8 installed?

TIA
Patrice

Except the fix does nothing, how on earth can you guys beta a program and break something like CPU hardware features? My system now believes it doesn’t support hardware Virtualisation.

  • 1 patch does change aswvmm but doesnt solve the prob

Typical Avast quality nowadays… ??? I really wonder how an Avast developers can manage to break something like this.

Hi,

but what problem you mean? Inability to play some games or “no hw virtualization” problem or virtual pc problem? Can you check version of aswVmm.sys file in windows\system32\drivers directory? Did you reboot computer after executing the patch? This patch should solve games and virtual pc problems. “No hw virtualization available” is actually not a problem, because Avast is using virtualization extensions of CPU to help protect your computer. If other virtualization SW is detected (like VirtualBox/VmWare), this feature is automatically disabled to not interfere with other VMM.

for example i have a portable drive genius app, that thing cant run under Avast 8 but run under 7

This path changes the version of file. But this file version change, changes nothing at all. :-\
And if you want this patch to change file vervion you need to turn off self defense module not just restarting the PC

Same issue here with Dead Space 3, as well as my wireless xbox 360 controller driver failing. So glad I updated all my clients to it. Yeesh.

12

Is there a possibility to disable that feature manually? Obviously an automatic detection isn’t working perfectly.

Bonjour,
Problem now solved.

  1. Disable Avast! self defense
  2. Replace aswVmm.sys in Windows\System32\Drivers directory with patch: http://files.avast.com/files/emupdate/20130304.exe executed as administrator
  3. Enable self defense again
  4. Reboot

Yesterday I tried w http://www2.avast.com/files/aswvmm/x64/aswvmm.zip which didn’t succeed.

Thanks to Spec8472

This is the same patch that doesnt work man…
SO problem is nor solved

15

Mine is solved with 20130304.exe, was not with aswvmm.zip . That’s enough… for me.
:wink:

16

I have tried both what you said and what max-support said, but nothing helps.

17

same here, no solution yet

18

Also, when attempting to make alterations to that folder, permissions are locked down, so it can’t be updated with the patches that have been suggested here (even when run as admin), I even tried just giving myself write access, still can’t replace the file. I didn’t want to dive deep on permissions because I was afraid I could screw up something or leave myself vulnerable to attack.

waouh boys…! let me post it again :
problem solved following exactly that procedure:

BTW, after patching you will have 2 files in your C:\Windows\System32\drivers:

  • a new aswVmm.sys (v 8.0.1482.47)
  • a aswvmm.sys.sum
20

I have done that exactly, nothing happens when I run the exe, no message, no error, and no update to the file when follow the directions exactly. And by disable self defense I assume you mean avast pro 8 completely?
