sap JCO3.0安装时遇到的问题

There are different distribution packages for various JRE versions and hardware processors available:

• sapjco3-ntintel-3.0.8.zip for a 32-bit JRE running on a 32- or 64-bit AMD or INTEL x86 or a 64-bit INTEL Itanium processor
• sapjco3-ntia64-3.0.8.zip for a 64-bit JRE running on a 64-bit INTEL Itanium processor
• sapjco3-ntamd64-3.0.8.zip for a 64-bit JRE running on a 64-bit AMD or INTEL x86 processor

Note: Before installing JCo, please install the latest Microsoft Visual Studio 2005 C/C++ runtime libraries as described in note 684106.

To install JCo for Windows unzip the appropriate distribution package into an arbitrary directory {sapjco3-install-path}.

Note: Do not copy the sapjco3.dll neither into the {windows-dir}\system32 nor into the {windows-dir}\SysWOW64 directory. This will break the operability of other JCo versions that are already installed on the same system. Furthermore you would risk that the current installation also would not work anymore, if thesapjco3.dll gets replaced in the respective Windows system directory in the future.

Then add {sapjco3-install-path} to the PATH environment variable.
Finally, add {sapjco3-install-path}\sapjco3.jar to your CLASSPATH environment variable.

安装时候请注意以上红色字体部分．

如果发生下面错误可能是没有安装　latest Microsoft Visual Studio 2005 C/C++ runtime libraries 请下载
