GUI not working anymore after installing of ABAP preview
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 ?
