Error installing Eclipse IDE on windows

java eclipse windows-8 installation

I just experienced a similar problem. Running the installer as administrator solved the problem for me.

So right click on the installer file (eclipse-inst-win64.exe) and then click on Run as administrator. Now just follow the prompts and you should be fine.

In case it matters, I did not update the installer, because it restarts and probably (i'm not sure) it won't restart in administrator mode.

Btw this was on a 64bit Windows 8.1 machine.

Also have a look at these two threads:

Hello everyone this is my first question here so I apologize for any missed expectations.

EDIT 1:

Downloaded Eclipse from : https://eclipse.org/downloads/download.php?file=/oomph/products/eclipse-inst-win64.exe

64-bit Windows 8

JDK Dir: C:\Program Files\Java

/Edit 1

I need to install the Eclipse IDE for Java programming for my Computer Science class and I have been trying for two days now with no success. I tried both the 64 and 32 bit installations and I get the exact same error. It's very frustrating because whenever I search all people talk about are "plug-ins".

Here is the error I get when installing:

This goes on even more will post the entire thing if needed but hoping there is something obvious I am missing. I have tried re-installing JDK, rebooting, re-downloading Eclipse, installing 32-bit versions of Eclipse and JDK and 64-bit for both. I also system restored to before I started any of it and tried again on a clean boot and got the same error.
