Do you have a value for DigitalProductID in Key:
MRANENIA is created if this Value is not present.
The Retail Install creates DigitalProductID when you enter the CD Key.
I have the DigitalProductID value at that location. It is a binary value, A3h bytes in length. Starting at byte 24h I have this string: "730-00847". Plugging that string into google turns up many hits to Windows 98 CD's being sold by various vendors - I am not sure how that number relates to win-98 - Microsoft product ID? Stock Number? Starting at byte 8 I have this string: "07604-oem-0002302-49210" - that also happens to be the string contained in the value "ProductId".
Anyone want to volunteer to delete MRANENIA to see what happens?
I have renamed the key in my registry to "backupMRANENIA" - I expect that is equivalent to deleting it. We'll see what happens.
PS: Under HKEY_Classes_root\CLSID\ I have key (guid?) with a value called "Windows Genuine Advantage Validation Tool" and under that a value called "AppID" with a value that looks like a guid. If I search for that guid I find a reg sting with a value "LegitCheckControl". I recall having to run a WGA program some time ago in order to download something from MS.
Edit: With the MRANENIA registry key renamed to "backupMRANENIA" and rebooting, the system starts just fine, and I seem to be able to access a data CD from my DVD/RW drive with no problems. Checking the registry, the system did not restore the MRANENIA key after rebooting - and the renamed key remains intact. I'm able to run FF2 and post this edit.
