Otherwise it will not be found when the client tries to instantiate the COM object. share|improve this answer answered May 19 '09 at 12:09 sharptooth 109k50315704 I did try using regasm on the full path of the assembly which is located in c:\temp, but still the same error –ingt May 19 '09 at 14:07 1 Then I guess your best bet is to start ProcessMonitor - technet.microsoft.com/ru-ru/sysinternals/bb896645.aspx - and look what file exactly is not found. It could be some dependent assembly you're not at all aware of. Once you know for sure it will be much easier to resolve. –sharptooth May 20 '09 at 4:51 sharptooth, thank you very much for this answer. It

In VS2008 the project property "Register for COM interop" is checked, and when I compile the DLL and try to use it on my development machine - it runs ok.

COM is not able to find your component in the registry. Here are some of the resolutions you http://hoy-sala.blogspot.com/2007/11/automation-error-system-cannot-find.html can try- Enable Register for COM interop in the project properties windowThis use to be enough in .Net 1.1 /VS 2003 to get the component registered. But in .Net 2.0/VS http://www.xtremevbtalk.com/general/321056-call-net-vb6.html 2005, Microsoft introduced another way to specify the COM visibility. That is by introducing a new attribute [assembly: ComVisible(true)]. Add this attribute to your AssemblyInfo.cs file and recompile the project.If automation error you are still having the problem, try registering the component explicitly usingregasm c:\abc\abc.dll /tlbsometimes the /tlb option does the trick.If this doesn't fix the problem check the version number of the component on which your component depends on. If the components, on which your component depends, are singed with specific key and are of specific version, then your component also need the system cannot to be signed with the same key and versioned the same. Otherwise you will get the same automation error when loading from the component from a COM client. In .Net2.0 you update the AssemblyInfo.cs to update the version number and sign the componente.g.[assembly: AssemblyVersion("x.x.x.x")][assembly: AssemblyFileVersion("x.x.x.x")][assembly: AssemblyKeyFile(@"your_key.snk")]Hope this helps.

General > Call .NET from VB6 Thread Tools Display Modes #1 04-27-2011, 07:40 AM rbrodbeck Freshman Join Date: Jun 2008 Posts: 33 Call .NET from VB6 I have an old VB6 project that needs to reference/call a new .NET project. My .NET project (ImportProspects) was built with the 'Register for COM interop' box checked on machine A. I copied the ImportProspects.dll and ImportProspects.tlb files to machine B (the dev machine for the VB6 project). In the VB6 project I added a reference to ImportProspects.tlb and added the following code: Code: Private Sub mnuUtilitiesImportProspectsTemplates_Click() Dim oImportTemplates As ImportProspects.ImportProspectsEntry Set oImportTemplates = New ImportProspects.ImportProspectsEntry MsgBox oImportTemplates.myFunction End Sub When I execute that code I receive the following error message: Run-time error '429': ActiveX component can't create object What am I doing wrong? rbrodbeck View Public Profile Find all posts by rbrodbeck #2 04-27-2011, 07:50 AM Gruff Bald Mountain Survivor Retired Moderator* Expert * Join Date: Aug 2003 Location: Oregon, USA Posts: 6,440 COM components Need to be registered with Windows on the target PC.
