This is quite a common error message, but there is a large number of possible programs where it has occurred.
The error box has a title bar, Microsoft Visual C++ debug Library. In the box is the message,
‘Debug error
Program c:\Program Files\BTvoyager 105 ADSL Modem\dslstat.exe
Abnormal Program Termination’
I have reinstalled the modem several times, with using the removal tools before reinstalling. The DSL light is always flashing, and always get error 678 when dialing. In thr BT error page it gives ‘Problem Code 90156’. BT Tech Support say it is an error in the registry which they are not allowed to help with. I have searched on Microsoft Knowledgebase and Technet without finding the solution. Can anyone help please?
