Michael,
If you're not already doing so, you should use Application.ServerName to establish where your files and paths are. This is the most reliable way to do this for COM servers. For example, you could do this in your Init method:

THIS.cAppStartPath = JustPath(Application.ServerName)+"\"
SET DEFA TO THIS.cappstartpath+'data\'+THIS.cAppName+'\'
THIS.cHTMLpath=THIS.cappstartpath+THIS.cAppName+'\HTML\'

Also, you should always use ComReturnError in your Error method...

>David. Thank you for your reply. I have inserted the code calling the COM and it is working but has a bug. I get the following errors:

Since doing this, the error message is displayed everytime I run VFP. I considered the possibility of a rogue INI file having an influence on the system. I have looked around, but found nothing. I have also checked the file locations in the setting of the IDE. Nothing seems out of order there. Any other ideas?
