Help please!!

Search for VBoxStartup.log using your hosts search function. It will be in your user space.

Finely it's done, I fix it, I've restored the original uxtheme.dll and now it's working.

Do you have a hacked Uxtheme.dll in your host? You need to post the startup.log as mpack asked.

I have the same error. I tried to place original uxtheme.dll file to the c:\Program Files\Oracle\VirtualBox\ directory, but error was not fixed. Could you help me, please?

Code: Select all

00:00:02.711076 supR3HardenedErrorV: supR3HardenedScreenImage/NtCreateSection: rc=VERR_LDRVI_NOT_SIGNED fImage=1 fProtect=0xf fAccess=0x10 \Device\HarddiskVolume1\Program Files\Oracle\VirtualBox\uxtheme.dll: Not signed.: \Device\HarddiskVolume1\Program Files\Oracle\VirtualBox\uxtheme.dll

You need to remove the theme hack.

Find the original (unhacked) uxtheme.dll file, as shipped with Windows. Your theme hacker will usually have made a backup of it somewhere. Place a copy of it inside the "C:\Program Files\Oracle\VirtualBox" folder. That should eliminate that particular problem.

I extracted original uxtheme.dll from Windows 7 installer image and copied it inside "C:\Program Files\Oracle\VirtualBox" folder. Could this file be cached somewhere? How can I make sure that uxtheme.dll is signed?

[mpack]

I don't think Windows caches DLLs in the way you mean, but if you are in any doubt then a full rebooting of the host would probably eliminate the question.

Unfortunatelly reboot didn't help me. I've attached original uxtheme.dll file. Could you check it?

[mpack]

I'm afraid not. I consider checking the correctness of Windows DLLs to be slightly beyond my remit. In any case I don't use your version of Windows.

It should be quite straightforward for you to check: look in the VBoxStartup.log - is VirtualBox still complaining about uxtheme.dll?

[noteirak]

It is located in the "Logs" subfolder of the VM folder.

I think you missed the second page of posts here Max...

[noteirak]

Seems like I did indeed, my bad...

Unfortunatelly yes. I see this row on log:

166c.1508: supR3HardenedScreenImage/NtCreateSection: rc=Unknown Status -22900 (0xffffa68c) fImage=1 fProtect=0xf fAccess=0x10 \Device\HarddiskVolume1\Program Files\Oracle\VirtualBox\uxtheme.dll: Not signed.: \Device\HarddiskVolume1\Program Files\Oracle\VirtualBox\uxtheme.dll
166c.1508: supR3HardenedWinVerifyCacheInsert: \Device\HarddiskVolume1\Program Files\Oracle\VirtualBox\uxtheme.dll

Only restoring original file in the "c:\Windows\System32\" folder helped me, but aero themes stoped working

[mpack]

Well, the error message shows that the DLL is clearly being loaded from the correct folder, but says it is still unsigned. So, I'm surprised that putting this DLL in a different folder makes it acceptable.

Is it possible to disable uxtheme.dll signing check?
