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: Can't load AMD 64-bit .dll on a IA 32-bit platform". 

However, I have the 64 bit JRE downloaded, and double-checked my java version:

C:\Program Files (x86)\apache-tomcat-7.0.34\bin>java -version java version "1.7.0_10" Java(TM) SE Runtime Environment (build 1.7.0_10-b18) Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode) 

I've seen this question here before, but in one there was no resolution, and in the other it was an Eclipse issue, but I'm getting this error when I access tomcat directly.

How do I find out which "IA 32 bit platform" is being detected, and how do I point Tomcat in the right direction? Also, could this be why my servlet is getting this 404 error through Eclipse?

Answer 1

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.
