BizTalk 2016 – Installing SAP Adapter- Microsoft.Adapters.SAP.SAPGInvoker.dll

After installing BizTalk adapter pack you would expect that enabling the SAP receive location port will just work. Guess what? Error!

Could not load file or assembly ‘Microsoft.Adapters.SAP.SAPGInvoker.dll’ or one of its dependencies. The specified module could not be found.
File name: ‘Microsoft.Adapters.SAP.SAPGInvoker.dll’

To solve this error you’ll need to install the SAP Libraries. Since i have a copy of previous SAP libraries, I’ve just reinstalled those, otherwise you’ll have to download it from SAP Market Place (you’ll need someone from your company that has access to those).

Steps:

  1. Install SAP NCO Libraries:
    1. NCo3018_Net40_x64.msi
    2. NCo3018_Net20_x86.msi
  2. Copy the SAP 3.0 libraries both x86 = 32bit, x64 = 64bit on the correct folder
    1. icudt26l.dll
    2. icuin26.dll
    3. icuuc26.dll
    4. librfc32u.dll
    5. libsapu16vc71.dll
    6. libsapucum.dll

32bit folder = C:\Windows\SysWOW64

64bit folder = C:\Windows\System32

3.  Restart the host instance
