Here is my problem:
I want to use j2pkcs11.dll in my java application. I downloaded dll from here and move it to system32 directory. When I run my code I have got :
java.lang.UnsatisfiedLinkError: C:\Windows\System32\j2pkcs11.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform
My OS is windows 7 64-bit and my jre is 64-bit too. Obviously I need to get 64-bit version of j2pkcs11.dll but when I searched the web I could not find it anywhere. Any clue?
Ok, for those who may encounter this problem, it seems that there is no support for j2pkcs11 in jre-64bit. So I install 32-bit jre and select this jre as my runtime jre in Intellij.

...but the 32-bit CAN find the 64-bit JDK.
When I open Android Studio I receive
Error launching Android Studio No JVM installation found. Please
install a 64-bit JDK. If you already have a JDK installed, define a
JAVA_HOME variable...
I have the 64-bit JDK installed with both PATH and JAVA_HOME set (confirmed this in cmd prompt)
PATH
...; C:\Program Files (x86)\Java\jdk1.8.0_91\bin
JAVA_HOME
C:\Program Files (x86)\Java\jdk1.8.0_91
I can, however, launch Android Studio by going to its bin folder and running the 32-bit launcher (studio.exe instead of studio64.exe).
Why would the 32-bit Android Studio be able to find the 64-bit jdk, and not the 64 bit AS?
Android Studio 64-bit works on both 32-bit and 64-bit JDK. Depending on your JDK installation you select the launcher:
studio.exe is the 32-bit launcher.
studio64.exe is the 64-bit launcher.
From your JDK path it's clear you have installed the 32-bit JDK. However, multiple JDKs can co-exist in one system so you can also install the 64-bit JDK if you wish.
I have a 64bit operating system with phpStorm 9.0.2 installed.
I get out of memory errors and it seems like JVM32bit might not help the cause.
How can I upgrade my JVM32bit version to JVM64bit?
Is it just as simple as downloading a 64bit version and installing it or are there any other extra steps to take to do this correctly?
OS Win 7 64bit
You can run PhpStorm even if you have no Java installed on your computer as on Windows it comes bundled with own 32-bit JRE which will be used by default ignoring your system-wide Java (if you have one).
That's why "uninstall 32-bit Java and just install 64-bit one instead" is not enough (as in some cases you simply have no system-wide Java installed on your computer).
Download and install 64-bit JDK (yes, it has to be JDK and not just JRE)
Create IDEA_JDK_64 environment variable and point it to JDK root folder. For example:
Use 64-bit PhpStorm's executable (PhpStorm64.exe) instead of 32-bit (PhpStorm.exe).
The above works just fine for me.
If anything -- please refer to official support article.
I have downloaded and installed IDEA 13.1. However, even having a 64-bit system, Windows has automatically installed the program in the folder Program Files (x86), which is dedicated for 32-bit programs.
Is there another download for the 64-bit version or maybe a special setting to make it suitable for a 64-bit system?
In C:\Program Files (x86)\JetBrains\${Intellij Idea version}\bin, there is an executable called idea64.exe. This is for 64-bit systems. You can simply change your IntelliJ shortcut path to it.
You also need to add a new environment variable IDEA_JDK_64 pointing to your 64-bit JDK so IntelliJ can use a 64-bit JDK.
idea64.exe uses this JDK search sequence:
IDEA_JDK_64 environment variable
..\jre64 directory
system Registry
JDK_HOME environment variable
JAVA_HOME environment variable

If installing latest version as of today 2016.3.2, while installing the installation wizard prompts to either choose 32-bit or 64-bit.
You need to install the Java SDK 64bit so it shows the options to install IntelliJ 64bit.
Today when i migrate a project from old server to new server, i encounter this problem when i test the deployed service codes.
javax.servlet.ServletException: java.lang.UnsatisfiedLinkError: E802: Can't load shared library. E:\Rochade\bin\msvcr71.dll E:\Rochade\bin\msvcr71.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform
no msvcr71 in java.library.path
i googled it on the internet and found some tips on installing a 36 bit jdk, i tried but didn't sovle the problem, does any one has any comment on this? i am really in hurry to get this problem solved, which is the road block for us moving forward on the migration process.
I think you cannot load library compiled for 32-bit architecture in 64-bit environment.
Solution is to recompile the library for x64 or obtain 64-bit version if you do not have its sources.
You either can use a 32-bit JVM or install the 64-bit version of the Microsoft Visual Studio C/C++ Redistributable Package.
Or better reinstall the software on the new server. Moving only the folders to a new computer is not a good idea on Windows, especially when the old PC was a 32-bit system and the new PC is a 64-bit system.
I had setup 64-bit eclipse with 64-bit JRE. I wanted to try QuickTime for Java but I realized that it is not compatible with 64-bit JRE. One option I have is to change over to 32-bit eclipse as well as 32-bit JRE. But I was wondering if same 64-bit Eclipse can be used along with 32-bit JRE also.
Please suggest!
EDIT: I guess I was not clear enough in my question. I do understand that I will need to use a 64-bit JRE to run 64-bit Eclipse. I only wanted to make sure that I can have a project in 64-bit Eclipse which uses a 32-bit JRE for execution.
Just include the 32bit JRE as an additional Java runtime in the configuration and use it for your project.
You cannot use 64-bit Eclipse with 32-bit JRE, but you can have both 32-bit and 64-bit JREs installed on your system. If you find that one or the other Eclipse fails to start in this situation, it is likely finding the wrong JRE. To remedy the situation, add the following lines to the start of your eclipse.ini file:
-vm
[fullpath]\javaw.exe
First, you need create a 32bit jre environment in menu windows/preferences/java/installed jres. Then, you can create a java project and select 32bit jre environment for 32bit java program.
