The Dll is compiled for 64 bit ( amd64 or x86_64 ) platform/cpu architecture while your windows OS/JVM/JRE installation is/are 32 bit.
Dll 是为 64 位（ amd64 或 x86_64 ）平台/cpu 架构编译的，而您的 Windows OS/JVM/JRE 安装是 32 位。
Either get a 32 bit version of the dll or upgrade your working environment ( either OS or JVM/JRE installation
获取 32 位版本的 dll 或升级您的工作环境（操作系统或 JVM/JRE 安装

Solved the architecture error.
解决了架构错误。
Lamans explanation for Error: OS was 64-bit, I Had 64-bit compiled .dll library and a 32-bit JDK 1.6.
Lamans 对错误的解释：操作系统是 64 位，我有 64 位编译的 .dll 库和 32 位 JDK 1.6。
Solution: I updated my JAVA_HOME variable from (JDK 1.6 32-bit) to (JDK 1.8 64bit).
解决方案：我将我的 JAVA_HOME 变量从（JDK 1.6 32 位）更新为（JDK 1.8 64 位）。
- Changed Java/JRE/JDK to 64bit environment
- Ugraded Java/JRE/JDK environment to JDK 1.8
- Upgraded from "Netbeans 6.9.1" to "Netbeans 8.2"
- Upgraded Netbeans "Default JDK" from "JDK 1.6" to JDK 1.8 worked.
- 将 Java/JRE/JDK 更改为 64 位环境
- 将 Java/JRE/JDK 环境升级到 JDK 1.8
- 从“Netbeans 6.9.1”升级到“Netbeans 8.2”
- 将 Netbeans“默认 JDK”从“JDK 1.6”升级到 JDK 1.8 工作。
Note: Netbeans JDK version can be found from IDE accessing Tools->Java Platforms->Platforms or use link "Changing java platform on which netbeans runs" to change default JDK for netbeans.
注意：Netbeans JDK 版本可以从IDE 访问Tools->Java Platforms->Platforms 或使用链接“更改运行netbeans 的java 平台”来更改netbeans 的默认JDK。

In my situaton, I just promise that Tomcat's bit was the same as the JDK's bit. I think this error doesn't matter to coding tools such as eclipse ,and bit of operating system.
在我的情况下，我只是保证 Tomcat 的位与 JDK 的位相同。我认为这个错误与 eclipse 等编码工具和一些操作系统无关。
