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:
((System.ComponentModel.ISupportInitialize)(this.a xMappointCtrl)).EndInit();
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.

Hi,
I got the same issue today .
have you found the solution ?

Thanks

Hi,

did you try the solotution from Richard?

Hi,
Yes i tried but does not work.

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.
