Excel x64 with x86 DLL refrence

I created an Excel addin that uses an SAP dll (SapROTWr.dll) to interact with SAP.

I had the x86 version of Excel and it worked fine

I have recently upgraded to Excel x64 and my addin no longer works

After debugging I saw that it is because SapROTWr.dll is x86.

Is there a way to get around this as I cannot find a x64 version of this dll.

Hello Darret,

No way, unfortunately. The problem is: by Windows design a process cannot load a DLL of a different bitness.
