REGDB_E_CLASSNOTREG when start VirtualBox 5.0 on W7

[KC Work]

When I try to start VirtualBox 5.0 on one of my Windows 7 laptops, I get the following error pop-up:

Failed to create the VirtualBoxClient COM object.
The application will now terminate.
Callee RC: REGDB_E_CLASSNOTREG (0x80040154)

Last few lines of log:

00:00:00.358800 HostDnsMonitorProxy::notify
00:00:00.436800 VD: VDInit finished
00:00:05.553609 Watcher ERROR [COM]: aRC=E_ACCESSDENIED (0x80070005) aIID={0169423f-46b4-cde9-91af-1e9d5b6cd945} aComponent={VirtualBoxWrap} aText={The object is not ready}, preserve=false aResultDetail=0

I have no problem to start 5.0 VBox on my other Windows 7 and XP.

I've tried suggestions in the other thread "Callee RC: REGDB_E_CLASSNOTREG (0x80040154) error on xp2" but no success.

Any idea? Please help.
Thanks

Cheers,
KC

I have exactly the same error and cannot find any others error logs

Note: I have tried to downgrade to latest 4.3.30 and got also an error
Do you also have the same error while downgrading?

Hum, if I set the compatibility to "Vista SP2", I can start the client, but I'm not able to start any VMs, even create a new one

I also tried to switch back to version 4, but the same error.

Has anybody a solution?

[mpack]

The error indicates an install problem, so just uninstall and then reinstall correctly. By correctly I mean installed for the correct user (not the Admin user account), and using "Run as administrator".

Do not mess around with compatibility modes, that can only add confusion. The current VirtualBox version is compatible enough already with all Windows versions except Win10.

Hi!

I have downloaded the latest version (5.0.2), deinstalled the old version and installed the new version, but i get the same error.

I did as you've suggested but the same problem still appear.

What is inside this W7 of my laptop is conflicting with the COM object to cause "Failed to create the VirtualBoxClient COM object".
Anything to do with the .NET in this W7, which has following .NET setup? See attached GIF image.

No problem on my other W7.

Hey,

I have identified one possible reason and found a solution. I posted it on StackOverflow:

I had the same problem on Windows 7 professional (error message: Callee RC:E_ACCESSDENIED (0x80070005)) and Windows 10 home (error message: Callee RC:REGDB_E_CLASSNOTREG (0x80040154)) ; on both systems creation of the com-object for VirtualBox failed. Multiple reinstallations failed. After new installation of Windows 7 and Virtualbox I compared a registry of a computer after fresh installation with no problem and the Windows 10 having this promlem. At the computers with the problem I found a registry key HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{819B4D85-9CEE-493C-B6FC-64FFE759B3C9} with three elements: (standard)="VirtualBox Application" and the two binary keys "AccessPermission" and "LaunchPermission". The fresh insalled computer did not have the keys "AccessPermission" and "LaunchPermission". After deleting "AccessPermission" and "LaunchPermission" on Windows 10 the problem was solved, even without reboot and new login. This also worked with Windows 7.
