Load API library

Description
With PLCSIM Advanced the interfaces of the API V2.0 are not compatible with the interfaces
of the API V1.0. However, the Runtime Manager of PLCSIM Advanced V2.0 is compatible
with the API of PLCSIM Advanced V1.0.
Earlier versions of the API are also installed during the installation of PLCSIM Advanced
V2.0.
The default path is:
● C:\Program Files (x86)\Common Files\Siemens\PLCSIMADV\API\1.0
● C:\Program Files (x86)\Common Files\Siemens\PLCSIMADV\API\2.0
The installation path of PLCSIM Advanced is contained in the registry:
● Key: "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Siemens\Shared
Tools\PLCSIMADV_SimRT"
● Value: "Path"
To maintain the path to the API, add the character string of the following subdirectory at the
end: "API\<API version>" (e.g. "API\2.0").
When you use this path the API library (DLL) is loaded directly from the installation directory.
