Can`t start Virtualbox RC: E_NOINTERFACE (0x80004002)

[Casufi]

I installed Virtualbox 4.3.8 without admin rights and then reinstalled it with admin rights (right click on the installer) but i am gatting the error message RC: E_NOINTERFACE (0x80004002) still.

I`ve attached virtualbox.xml

[mpack]

VirtualBox.xml is not useful. It's a config file, not a log.

Did you uninstall before reinstalling?

[didier.gilles]

Don't care if the xml is usefull or not.
I have same problem. And nobody can help us. Except asking us if we installed correctly the program...
What a pity...

[mpack]

It is certain that nobody can help you if you fail to provide even basic data for diagnostics.

[didier.gilles]

And how can we helped if you don't tell us what file we shoud provide ?

You could start by looking at the FAQ section of the site, particularly the one that describes Minimum information needed for assistance.

And, be aware that even if you were a paying customer, this is not an Oracle support site: it's a user site manned by volunteer users who owe you nothing, so you'd be well advised to be polite to those you hope will help you.

Exactly the same problem.

Fresh install. The VirtualBox Manager never opens.

VirtualBox-4.3.8-92456-Win

Host is Win.7 Pro, service pack 1 (32 bit OS), running on a Dell Latitude E6410 with 4GB RAM.

There is nothing to say about a Guest, there isn't one yet.

The user manual says to look for the process VBoxSVC.exe - does not exist. There is a COMSysApp service but it is not running.

what about re-registering some core dlls?

regsvr32 /s corpol.dll
regsvr32 /s mstime.dll
regsvr32 /s /i /n wininet.dll
regsvr32 /s extmgr.dll
regsvr32 /s oleacc.dll
regsvr32 /s ole32.dll
regsvr32 /s comcat.dll
regsvr32 /s /i /n comctl32.dll
regsvr32 /s cryptdlg.dll
regsvr32 /s oleaut32.dll

For me this has been happening for many months. Currently using 4.2.16 as the last most reliable version. There have been posts on this topic for some months (one I had bookmarked has gone though) so was hoping 4.3.10 has resolved the problem.

Host - Windows 7 64 bit

Looking forward to a solution from the experts on the forum. TIA. Andrew

Finally! This did it for me. Since I haven't been here for a day yet, I probably can't post this u-r-l so I'll have to mangle it:

It seems silly that I can't even post u-r-ls from this very site, never mind from superextra-spamware-installer-sitedotcom.
