SAP GUI librfc32.dll Issue

ISSUE:

Users may experience an SAP GUI error when attempting to run the AutoPost feature or execute a web service using Winshuttle SERVER. The error may appear like this:


Cannot access librfc32.dll.
Please put a 64-bit version of librfc32.dll in your System32 folder (typically C:\Windows\System32) and a 32-bit version of librfc32.dll in your SysWow64 folder (typically C:\Windows\SysWow64).
You can get both versions from SAP Service Marketplace.

BACKGROUND:

Excerpt from Note 66971

SAP GUI on 64bit platforms

Currently there is no separate SAP GUI version for 64bit operating systems. However due to the limitations mentioned in SAP note 1442028 SAP is evaluating to create and ship a 64bit version of SAP GUI for Windows (x64). This note will be updated once a development plan and shipment schedule has been determined. Fact is that before 2013 no 64bit SAP GUI for Windows version will be available due to the huge effort associated with creating such a version.

WORKAROUND:

Winshuttle is legally prohibited from supplying the file (librfc32.dll) in question. We have a workaround and should be considered during installations (currently not covered in our deployment guide):

  1. Read the attached document to obtain the proper .dll
  2. Ensure that SAP GUI is installed on the target Winshuttle SERVER
  3. Copy the existing 'librfc32.dll' from the 'system32' folder to the 'syswow64' folder
  4. Replace the 'librfc32.dll' in the 'system32' folder with the x64bit version
