I would be very thankfull for any help on the following problem.
I have a problem with an application that runs under XP but does not run under Windows 7.
The application is using MapPoint 2006 and the MapPoint Control 13.0.
It throws an exception within the main Forms.Designer.cs at the following line:
The exception states: "COMException was unhandled Class not registered
Exception from HRESULT:0x80040154 (REGDB_E_CLASSNOTREG)

The exception is saying that MapPoint is not registered with the operating system.
Try running MapPoint from the command line with the /regserver flag
("mappoint /help" gives you a list of all options)
Re-installing MapPoint might also fix it. Make sure it is installed for the current user.

Running mappoint.exe /regserver at the command line (in the program files folder) can solve lots of problems when there are or were multiple copies of MapPoint installed.

Great - how do you install an XP virtual machine? I have a 64-bit laptop and use VmWare, I have a couple different XP virtual machines I find indispensable.

MapPoint 2006 predates Windows 7 by three and a half years: you might be out of luck.
If MapPoint 2009 and 2010 work - why not use them?

I see what you mean and you are right but I need mappoint 2006 to work within windows 7 for an old customer for maintenance perposes.

I get the same error with MP2010. Did you ever come across a solution for this? After doing research it appears this problem is related to the new session 0 isolation used in Vista/Windows 7. In our software, we are attempting to call some MapPoint functions from a windows service and get the error. It looks like you can't call MapPoint functions in session 0. It works in XP because services and UI run in the same session. Is there a way to use MapPoint functions in session 0? We don't need any visual interface (UI), with MapPoint, but it appears this is required. Can any MapPoint representative confirm this?
