Java will not run on Windows 7 x64


I recently built a new computer and installed Windows 7 Ultimate 64bit.

I have had absolutely no issues except with Java.  The first install that I tried was the latest 64bit version of Java and it crashed right after install.  I then tried uninstalling and installing the 32bit instead but same problem.

I have tried installing several older versions both 32bit and 64bit and they crash as well, always uninstall the old before installing the new.  Tried a different install directory and that didn't work.

When I install Java it crashes right after the install.  I can't even open the applet in the control panel.  Here are the details from the application event log:

Faulting application name: javaw.exe, version:, time stamp: 0x4d4a0b98
Faulting module name: java.dll, version:, time stamp: 0x4d4a3fad
Exception code: 0xc0000005
Fault offset: 0x00004e2f
Faulting process id: 0xc20
Faulting application start time: 0x01cbd85d448b2bff
Faulting application path: C:\Program Files (x86)\Java\bin\javaw.exe
Faulting module path: C:\Program Files (x86)\Java\bin\java.dll
Report Id: 840d671b-4450-11e0-b1ad-005056c00008

Any ideas?

where are you getting your java install package?
have you tried downloading an offline 64-bit install?
Reece DoddsCommented:
If you are using:
•32-bit Internet Explorer (IE), you need to download 32-bit Java (Verify browser)
•64-bit IE, you need to download 64-bit Java (Verify browser)
•Both 32-bit and 64-bit IE, you need to download both 32-bit and 64-bit Java respectively

I got the newest version from the java site, offline install.

I always use IE 32bit.  But the problem is that I get the error right after installing Java and can't even run the applet in control panel. (get the same error).  

I tried older versions only after trying the latest 64bit package, then 32 bit package.

I'm trying to run PMServer which requires java but error when trying to run.

.Net4 framework installed?

Use MSCONFIG to turn off a few startup apps and non-windows services to see if there is something running in the background causing a conflict.

You on Win7 SP1 yet?

If you want to uninstall java. Just do these steps.

1. Download


2. Select pro option.

3. Uninstall the product.

4. It will go through 3 stages. Make sure you complete those steps.

5. Restart the computer

Got to www.java.com and install the latest software.

I have installed SP1.

.net4 client framework was installed so I removed that, rebooted.  Tried installing Java but still get error when trying to run the applet or apps from the web.

Also tried removing other apps I had installed such as Office 2010, SQL, MS Security Essentials, and still no luck.

I do have VMWare server installed with 1 SBS 2003 virtual machine running but I don't think that should cause any problem.

I have removed nearly every program and if this doesn't work soon looks like a fresh re-install of Win 7  and install java first off.
Reece DoddsCommented:
did you try my suggestion about disabling auto-startup programs and services using MSCONFIG?

It is possible that something already running could be causing a conflict or stopping the install before it completes.
mr-frankAuthor Commented:
I did try disabling auto starts and services.  No luck.

I then did a fresh install of 7 ultimate x64.  First thing I did was install Java but when I went to the control panel applet it crashed again.

Then did a fresh install of 7 ultimate x32.  Java installed first but crashed again.  

All Windows 7 disks are legit and I have used before with no problems.

I ended up replacing the motherboard, CPU, and DVD burner.  Installed 7 ultimate x64 and java worked fine.

So it appears to have been a hardware issue of some kind.  A technical person I highly respect because of his long experience in the industry told me he has had a similar issue and he ended up replacing hardware piece by piece, and found that the DVD burner for some reason was causing java to crash.

So take whatever you want from that.

Motherboard and CPU that I had were MSI K9NBPM2-FID and AMD X2 6000+ (AM2) but I suspect is was the burner causing the problem.  No way to verify.
