Running SAP GUI on Winshuttle SERVER x64bit version

If you are running SERVER on a 64-bit OS, the default SAP install presents the following error:

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.

More info available from SAP Note 66971

SAP GUI on 64-bit platforms

Currently, SAP does not have a separate SAP GUI for 64-bit operating systems. However, because of the limitations mentioned in SAP note 1442028, SAP is considering creating one.

Winshuttle is legally prohibited from supplying the file in question, librfc32.dll. Winshuttle developed a workaround that should be performed before you install Winshuttle SERVER.

  1. Ensure that SAP GUI is installed on the target Winshuttle SERVER machine.
  2. Copy the existing librfc32.dll from the system32 folder to the syswow64 folder.
  3. Download the x64-bit version from the SAP Marketplace and replace the librfc32.dll in the system32 folder with the x64-bit version.
