GUI not working anymore after installing of ABAP preview

[elko_hasse]

Hi,

I have sapgui 6.40 installed on my computer.

Now after installing the Netweaver Preview ABAP stack (the installation worked fine) I cannot start my sapgui anymore.

I get a messagebox with the following message:

"The procedure entry point RfcResetTraceDir could not be located in the dynamic link library LIBRFC32.dll".

The current version of the LIBRFC32.dll in the system32 directory is 7.xx.

I replaced it with an 6.xx version, but it didnt help.

As far as I know the RFC dll is up- and downwards compatible, so I cant explain this error.

Any suggestions ?

Regards,

Elko

Now I deinstalled SAPGUI from my system and reinstalled the 6.40 version.

But I get still the same error. Whats the problem. Why is the Netweaver Preview messing up my GUI installation ??

Hi all,

after installing Patch 18 for GUI 4.60 it works fine again. I dont understand why, I always thought the RFC LIB is not specific for the GUI release.
