If you have multiple installations it can be confusing working out which copy you are actually running.  Looking in the registry at:

HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{EDFA6FE2-C2C5-4BE1-9F12-F1ED37D85EE2}\InprocServer32

will tell you where the file(s) are being run from.

If you want to manually register the dll to a particular location you need to open a cmd window as Administrator and then run:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm.exe /codebase /tlb C:\AMS\CMSI_v2.2.0a\code\XGMapLinkArcgisExtension.dll

C:\Program Files (x86)\Common Files\ArcGIS\bin\ESRIRegasm.exe" /p:Desktop C:\AMS\CMSI_v2.2.0a\code\XGMapLinkArcgisExtension.dll

Your edits could not be saved
Error HRESULT E-FAIL has been returned from a call to a COM component.
Would you like to keep the temporary edit layers in the map?

The problem is due to a fault with the MS Access database that forms the geodatabase, which means after a feature has been moved or deleted the database tries to reuse that ID value and this upsets the autonumber process, or so we believe.

At present we do not have a solution to this problem but we do have a bit of code that can be used to reset the autonumber values for any chosen field. This code can be used as a function and bundled in an mdb with a macro that runs the function and sent out to clients as needed. The code for the functions is as follows (this was originally Hartmut's code but I modified from the a sub to a function adding the return and msgbox, just so I could see that something was happening):

Public Function ResetAutoNumber(ByVal tableName As String, ByVal autoNumberColumnName As String)
    Dim maxAutoNumber As Long
    maxAutoNumber = DMax(autoNumberColumnName, tableName) + 1
    DoCmd.RunSQL "ALTER TABLE " & tableName & " ALTER COLUMN " & autoNumberColumnName & " COUNTER(" & maxAutoNumber & ",1)"
    ResetAutoNumber = True
    MsgBox tableName + " done!"
End Function

And macro simple needs to have a number of RunCode lines that call this function for each of the layers in the personal geodatabase, like so:

RunCode

       Function Name ResetAutoNumber ("Mon_point", "OBJECTID")

RunCode

       Function Name ResetAutoNumber ("Mon_poly", "OBJECTID")

RunCode

       Function Name ResetAutoNumber ("Mon_line", "OBJECTID")

• Add a new field to the feature class called, for example, VertexCount
• Use the Calculate Field tool within the attribute table, or in ArcToolbox, with the following Python expression - !shape!.pointcount
• Sort the feature class on the VertexCount field to find the worst offenders. If there is any bad geometry the expression may trip up, which is informative in itself.
• You can now select only the most complex features for generalising.

See the following article for more information. I have not tried the dicing method that is discussed later in the article: http://blogs.esri.com/esri/arcgis/2010/07/23/dicing-godzillas-features-with-too-many-vertices/

When ArcGIS 10 is packaged in an AppV sequence (bubble), to be used with HBSMR or CAMS, in their own sequences, {a4d1597d-bc1c-4f37-b12a-4bcb2cd2ec2f}_xgmaplinkarcmapextension.ecfg must be present in the real file store rather than Virtual File Store. Ie :

%ProgramFiles(x86)%\Common Files\ArcGIS\Desktop10.0\Configuration\CATID\{a4d1597d-bc1c-4f37-b12a-4bcb2cd2ec2f}_xgmaplinkarcmapextension.ecfg

The GUIDs shown above are for MapLink v4. The following GUID: {a315d61f-0f18-41c8-88dc-f650ae76014c} is for MapLink v5 for ArcGIS.

AccessField1==Dlookup("NGRoutput([Easting],[Northing])","Mon","[MonUID]=""#MonUID#"""))

AccessField2==Dlookup("Left([Summary],254)","Mon","[MonUID]=""#MonUID#""")
