For running the program you also need the SAP Java Connector from SAP (short: SAP JCo). 
This is normally not installed on every computer. 
It can be downloaded here: http://service.sap.com/connectors. For getting access to 
the download files you need an SAP Market Place User or "SAP S User ID". 
In case you don't have one your company should be able to create it. 
There is also a possibility to get one directly from SAP using this address: 
  https://support.sap.com/en/contact-us.html.
However, this tool is intended for SAP IT staff and not for the SAP end user, 
therefore an SAP S User ID should be there for the targeted users.

You need at least these 2 files:
- sapJCo3.jar
- sapJCo3.dll
Both files are to be available with the same version (this is of course the case 
if you install the SAP JCo).
The first file "sapJCo3.jar" has to be placed in the subdirectory "Sc4SAP_lib". 
The other file "sapJCo3.dll" has to be placed either
  - in the subdirectory "Sc4SAP_lib", too
  or
  - in a directory that is included in the system path (for Windows systems the
    subdirectory "system32" in the Windows directory would be a suitable place).

Both files are property of SAP and not allowed for us to distribute them. They are not part of our product.

On Windows platforms, SAP JCo in version 3.1 (and probably also higher versions) requires the 
Visual Studio 2013 C/C++ runtime libraries to be installed on the system. If not present, download and 
install the "Visual C++ 2013 Redistributable Package" from the Microsoft knowledge base article 
https://support.microsoft.com/en-us/help/4032938 and choose the package, which corresponds to the used 
Locale and JVM bit-width (x64 for 64-bit or x86 for 32-bit).

If the SAP JCo files are not present or not runnable, the application will not start!

You can use the provided program "Sc4SAPStarter.exe" to check whether the preconditions are given resp. which 
missing requirement prevents "Shortcut for SAP systems" from starting. It also offers the possibility to search for
a missing file in the accessible directories of your computer. There is a chance that the missing files 
already exist somewhere on your computer or on accessible drives, so give it a try.
