Unable to install JMonkey platform

EDIT: I think I made a dumb mistake, I downloaded the x86 version when I should have gotten the x64 version. Downloading the other one now, but I’ll leave this here incase someone else tries to google the error. x86 is 32 bit and x86 is 64!

Hi there, I’m trying to install the IDE, I’m on 64bit Ubuntu 16.x, and my JDK is Oracle 1.8.0_121 and is also 64 bit.

When I run the x86 installer I get the following output:

Configuring the installer...
Searching for JVM on the system...
Preparing bundled JVM ...
Extracting installation data...
Running the installer wizard...
An error occured while initializing the NetBeans IDE installer UI.
Most probably the running JVM is not compatible with the current platform.**

Exception:
  java.lang.UnsatisfiedLinkError:

You can get more details about the issue in the installer log file:
 /root/.jmonkeyplatform-installer/log/20170315103739.log

I’ve done quite a lot of googling but have come up with nothing.
The link in the error tells me that theres a mismatched 32 vs 64 thing going on, but I’m pretty sure thats not the case.

Seems to be the missing libXrender.so.1 but I dont know.

Cheers

The installer has everything prebuilt for the relevant architecture.

X86 = 32bit and X64 = 64 bit, so you downloaded the wrong file actually
