Register and Unregistered DLL & Automation Variables on Windows Server 2012

Hello Friends,

Last week i am working one of the requirement form client regarding FTP in Navision 2009 R2 using Automation variables.

General Approach – To register a dll - Using cmd

1 – Run cmd as administrator

2 – Go to main C: by using command – cd\

3 – Go to Folder FTPFileManagementWithSSL where your dll is located using command - cd FTPFileManagementWithSSL

4 – Execute Command - tlbexp FTPFileManagementWithSSL.dll /out: FTPFileManagementWithSSL.tlb

5 – Execute Command - "C:\Windows\Microsoft.NET\Framework\v2.0.50727\regasm" /tlb: FTPFileManagementWithSSL.tlb FTPFileManagementWithSSL.dll

6 – Execute Command - "C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\gacutil" /i FTPFileManagementWithSSL.dll

DLL Registered successfully – Only in those cases where Microsoft SDKs are installed.

But even using above approach I was getting error – “Automation Control was not registered Successfully” when I used Automation variable in code.

Error

---------------------------

Microsoft Dynamics NAV Classic

---------------------------

This message is for C/AL programmers:

Could not create an instance of the OLE control or Automation server identified by

GUID={6B57267D-A9B1-4C21-9360-E350B57C71AF} 2.0:{D70659DB-C298-3D6B-98BC-C369261DD352}:'FTPFileManagementWithSSL'.FTPFileManagementWithSSL.

Check that the OLE control or Automation server is correctly installed and registered.

OK

Newer Approach – To register a dll - Using cmd and PowerShell – Windows server 2012

1 – Run cmd as administrator

2 – Go to main C: by using command – cd\

3 – Go to Folder FTPFileManagementWithSSL where your dll is located using command - cd FTPFileManagementWithSSL

4 – Execute Command - tlbexp FTPFileManagementWithSSL.dll /out: FTPFileManagementWithSSL.tlb

5 – Run Windows PowerShell as Administrator

6 – Execute Below Command – For Regasm

."C:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe" -codebase -tlb "C:\FTPFileManagementWithSSL\FTPFileManagementWithSSL.dll"

7 – Execute Below Command – For gacutil

Set-location "c:\FTPFileManagementWithSSL"

[System.Reflection.Assembly]::Load("System.EnterpriseServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")

$publish = New-Object System.EnterpriseServices.Internal.Publish

$publish.GacInstall("c:\FTPFileManagementWithSSL\FTPFileManagementWithSSL.dll")

iisreset

Dll Registered successfully. And When I ran my code using Automation Variable my error got resolved.

Also if we want to unregister dll from Gac execute below command,

Set-location "c:\FTPFileManagementWithSSL"

[System.Reflection.Assembly]::Load("System.EnterpriseServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")

$publish = New-Object System.EnterpriseServices.Internal.Publish

$publish.GacRemove("c:\FTPFileManagementWithSSL\FTPFileManagementWithSSL.dll")

iisreset

I hope this will help you in future

Thank you for reading
