Profiler connection not established - Win 2003 SP1, .NET 2.0

When I run the new NCover 1.5.5 (Sorry I haven't tried it on older version) NCover hangs, and I get this error message in the event log:

.NET Runtime version 2.0.50727.42 - Failed to CoCreate profiler.

I did try the steps listed in this post as well to no avail:
http://ncover.org/SITE/forums/post/94.aspx

I've tried executing the cmd line listed below as an admin and got the same errors.

None of the MbUnit reportsare created either :(

Server Specs:
Windows Server 2003 Enterprise Edition with SP1
Dual 2.8 GHz Xeon's
1GB of RAM

Here is the command line I'm using to launch NCover.Console.exe

d:\builds\Telehealth\Code\tools\NCover\NCover.Console.exe //x d:\builds\Telehealth\Code\Reporting\NCover-result.xml //l d:\builds\Telehealth\Code\Reporting\NCover-Coverage.log //w d:\builds\Telehealth\Code d:\builds\Telehealth\Code\tools\MbUnit\MbUnit.Cons.exe /assembly-path:D:\builds\Telehealth\Code\AllUnitTests /report-folder:d:\builds\Telehealth\Code\Reporting /report-name-format:MbUnit-result /report-type:Xml D:\builds\Telehealth\Code\AllUnitTests\StackFixture.dll

On the console, I see the following output:

Sorry if this message is a little bit disjointed, I'm trying to fill in every possible piece of information I can think of that may be needed.

Re: NCover/NUnit 2.2.7 - Constantly Accesses DVD Drive

If you code doesn't requests drive D: the certain reason: CoverLib.dll was incorrectly registered.

Look at italic registry entry. If you have there path to your DVD drive it might cause the problem

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\CLSID\{6287B5F9-08A1-45E7-9498-B5B2E7B02995}]
@="NCover Coverage Profiler"

Re: NCover/NUnit 2.2.7 - Constantly Accesses DVD Drive

This was not the problem, as everything was registered correctly.

The problem was actually caused by the removable CD/DVD drive in my Dell Latitude D620 laptop. Ejecting it and reinserting it cured the problem.

Re: NCover/NUnit 2.2.7 - Constantly Accesses DVD Drive

I had the exact same problem, rebooting solved it.

Right before the popop from nunit-console.exe began, I had removed a burned CD from the rw DVD drive. Dont know if it matters, but my computer is also a DELL (Optiplex GX620).
