GUI 750 - install caused VBA RFC call to SAP to fail


Hello all,

We have a process that uses Excel files that have VBA macro code that logs into SAP and then executes a function module by RFC to validate the data in the file.

Since installing the 750 GUI, from 740, we are experiencing an error in the VBA code because of a missing reference, "SAP Remote Function Call: COM support". The file reference it can't find is "C:\WINDOWS\system32\librfc32.dll".

I have read several notes that talk about replacing the classical RFC with NWRFC. But I haven't read anything that gives the details about how to do that. 2417687 2256415 1025361

Does anyone who has installed GUI 750 know the steps that need to be executed to get past this problem?

FYI - this is only causing me a problem, not any of the users performing this process in production. I am the only user on GUI 750 at my company.

A post in the archive asked several question that were not answered. The answers to questions 3-4, that information would be very useful.
