Automation Error The System Cannot Find The File Specified Tlb

Join them; it only takes a minute: Sign ms access automation error. the system cannot find the file specified up COM registration fails: “Automation error: the system cannot find the file specified”, when installing dll into other folder than the tlb file up vote 3 down vote favorite We have a COM component (let's call it MyLib) developed in VB.NET,

for our Access application (let's call it MyApp) to use. In order to do that, we need to do COM registration using the generated MyLib.dll and MyLib.tlb files. When I am installing both files into our MyApp's folder, everything is working fine, the COM function is invoked correctly. However, I am having an error mentioned in the title when I am installing the dll into a common folder - the reason I am doing it is because we want to allow different versions automation error in vba of MyApp to be installed on the same machine. So if the COM component doesn't change, we of course want to share it among these different versions and let Windows do the reference count. I am not sure where I should put the MyLib.tlb file, either in MyApp's installation folder, or the same common folder as MyLib.dll. But anyway, I tried both locations, and they all gave the same error. I tried to compare the registry files between the case when I put MyLib.* into MyApp's folder, and the case when I put MyLib.dll into common folder. I can't see any difference except of course the CodeBase of the Class I am trying to register under HKCR\Wow6432nodes\CLSID{MYCLSID}\InprocServer32. Another thing I don't understand is there is no sub-key named TypeLib under HKCR\Wow6432nodes\CLSID{MYCLSID} in both cases, which in my understanding is the way to link the TypeLib to the dll (but why is is still working when I put tlb and dll into the same folder?) since in MyApp it only knows that there is a reference we add by reference of MyLib.tlb. I don't understand exactly how COM reference works for Access application, so if I am wrong please correct me. Can anybody tell me what I did wrong? What is the correct way to register a shared COM dll (whether put both dll and tlb into shared folder or not)? Thanks! UPDATE: Regarding the COM registration, I am using WIX to create a Windows installer and heat.exe t

Your class in .NET should be decorated like this: [GuidAttribute("BA713700-522D-466e-8DD4-225884504678")] public class MyClass This way your class will get compiled with the same GUID attribute every time you run regasm against it. If you do not include this attribute, regasm will auto-assign a different GUID every time. To be completely safe, your clas

Wednesday, August 29, 2007 3:09 AM Answers 0 Sign in to vote Hi Dave, When you ran it as an .exe file did you have your .NET Dll in the same directory? On a target machine you need to run regasm (with /codebase if you want a relative path). If you have a dependency on stdole.dll, do you have that in the GAC? (If you don't have it referenced in your .NET project then don't worry about this one). Hope that helps, let me know if you're still having issues with it.

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.
