tcnative-1.dll Can't load AMD 64-bit .dll on a IA 32-bit platform

Question

I\'m getting this error when I try to run tomcat:

"java.lang.UnsatisfiedLinkError: C:\\Program Files (x86)\\apache-tomcat-7.0.34\\bin\\tcnative-1.dll: Ca         


        

Answer 1

Please check your Project SDK version used by IDE.

In Intellij IDEA:  File -> Project Structure -> Project.
In Eclipse:        Properties -> Java Compiler.

Switch it to JDK x64 version installed.

Answer 2

Oh man, I found the problem. I had an old JRE in a weird place which was being accessed by JRE_HOME. I removed that dir, fixed my environment variables, and that took care of it.

Answer 3

I just found the solution. The problem was that my JRE_HOME pointed to a 32 bit JRE where in my machine was a 64 bit machine. I installed the 64 bit JRE and replaced it in the system variable and the server started clean

Answer 4

Please check your default version pointed by eclipse.Properties->Java Compiler. Switch it to your JRE version installed. This worked for me. Thanks.

Necromancing on a windows server (March 2019). There are several answers on stack overflow, for the problem Can't load AMD 64-bit .dll on a IA 32-bit platform". All show just part of the solution. Here is everything together.

The cause: a 32 bit version of Java is used, while the library expects a 64-bit version.

(1) Make sure JAVA_HOME and CATALINA_HOME is set. Something like

set JAVA_HOME=C:\Program Files\Java\jre1.8.0_201 set CATALINA_HOME=C:\Program Files (x86)\tomcat-9.0.16

These were the default locations in March 2019. The real versions don't matter, what is important that the following commands should work:

"%java_home%\bin\java.exe" -version
"%catalina_home%\bin\configtest.bat"

The first command should give you a few lines. One of the lines should say something like

Java HotSpot(TM) 64-bit Server VM

Of course 64-bit only on a 64-bit windows machine. (how to check: windows - run - system information. It should mention in System Type whether is is a 32 or 54 based system)

The config test shows you the java and catalina home values that are used by TomCat.

If you have the incorrect Java version:

• Uninstall old Java version: Control Panel - (main page) Programs - Uninstall a program
• Go to download Java manual download page. (Google if the link doesn't work anymore) Don't do automatic downloads, you might get a different version than you want, depending on your browsers.
• Download windows offline 64-bit Don't do the online, again: it looks at your browsers to decide whether you want 32 or 64-bit.
• run the installer.
• After installing Java, check your Path and your environment variables and adjust accordingly (In windows server 2012: Control Panel - System and Security - System - Change Settings - Advanced - Environment Variables) -re-open a command prompt. Check Path and environment variables again and run the tests above.

For the same message "Can't load IA 32-bit .dll on a AMD 64-bit platform" while trying to run a Jenkins slave on 64 bit windows machine, fixed it by removing JAVA_TOOL_OPTIONS and _JAVA_OPTIONS environment variables which were pointing to 32 bit jvmhook.
