Hi,
Solved copying the file vcruntime140_1.dll into C:\nwrfcsdk\lib
Yes, thet should be the DLL mentioned in prerequisites. Can you confirm that rfcexec.exe
works without it?
Hi,
The prerequisite at https://github.com/SAP/node-rfc and note 2573790 is: "Visual C++ Redistributable Packages for Visual Studio 2013"
I had already this package installed on my system.
Using process monitor I get this:
Copied the missing file from another program folder (microsoft teams) and now it's fine.
Yes, rfcexec.exe works without it.
Thank you Sam
On a fresh new Windows 10 system, with Visual C Redistributable 2013 installed, the file is present both in Windows\System
and in VC Redistributable:
I also tested and rfcexec.exe
works without this file but node-rfc not, good to know.
The VC runtime re-installation should normally fix missing files, otherwise fresh new Windows installation. There are similar problems reported by users who previously uninstalled older VC runtimes or similar Microsoft SDKs, before installing the newer one.
Hi,
I reinstalled the VC runtime 2013, repair options but no resolved.
Thank you for support Sam
The repair and reinstallation do not always work on Windows. Users spend hours and days sometimes trying to make it work that way and finish with Windows re-installation. You may try with Windows trial fresh new install first.
Hi,
On windows when I try to load the node-rfc module with: const r = require ('node-rfc')
I get the message error: Impossibile trovare il modulo specificato In english should be "The specified module could not be found"
In the path the %SAPNWRFC_HOME%\lib is correct, launching the set command to check the path I get: Path=...;C:\nwrfcsdk\bin;C:\nwrfcsdk\lib;
(no problems using it on ubuntu)
Thank you for help Sam
