librfc32.dll

[Former Member]

I have several web services built using the connector 2.0. After I deploy to a bare production machine, I also copied the librfc32.dll to the system32 folder. When I try to use the web services, I get the followig message:

DllExceptionNotFound (cannot find librfc32.dll)

any help is appreciated.

Note: in development, I installed the SAP GUI on the machines and never encountered any problems. Installing the SAP GUI is not an option on the production machines.

Hi,

Did you also deploy SAP.Connector.dll and SAP.Connector.Rfc.dll with your apps and how?

SAPGUI is not a required part of .NET Connector deployment.

Ye, the SAP.Connector.dll and SAP.Connector.Rfc.dll were automatically packaged with the msi install. They are installed in the bin folder under the web application folder. I manually copied the librfc32.dll to the system32 folder.

I still get the message that the librfc32 cannot be found. There are similar messages to this one on this bulletin board, yet none seem to have the correct or full answer. There must be some other dependencies which are not documented.

Hello,

Sounds like a security setting issue. Can you please put the librfc32.dll to the bin directory of your web app and have a try again?

I have tried putting the librfc32 in both the system32 and the bin folder under the web application. I still have the same issue.

any help is appreciated.

How about to make a test with a Console app and provide us with the complete exception description if any?

Hi,

This is a bit of a "shot in the dark", but have you made sure the NT user that the IIS web app is using has the needed rights? this might be a problem in case you changed the default at some point.

No security has been modified since this is a brand new Windows 2003 install. I have tried installing the SAP GUI and the problem goes away. However, I really need to build an install not dependent on the SAP GUI.

can you please check wether you have also copied

MSCVR71.dll and MSCVP71.dll to C:\WINN\system32

(These dlls are also required by the librfc32.dll). If you do not have them, you can also download them from SAP Marketplace and install them

extra. To install the missing DLLs(MSCVR71.dll and

MSCVP71.dll), download and unpack the archive attached

to "Note 684106" with sapcar and

execute "R3DLLINS.EXE".(SAPCAR is a compress utility

similar to winzip, tar, etc., that is used by SAP to

compress and decompress nearly all delivered files.)

OR you can download sapcar at

http://service.sap.com/patches

That was the culprit.

Thanks - that worked for me too.

Although, the file names were: msvcp71.dll, and msvcr71.dll.

I simply copied them from the \Windows\System32 folder to my Bin folder of my project, and it works perfect.

Thanks Again!
