Thingsboard Windows Installation Error

When i run the install.bat file on a windows 7 machine. i receive the following error:
Detecting Java version installed. Detecting if it is 64 bit machine
CurrentVersion Detecting if it is 32 bit machine CurrentVersion 1.8
Java 1.8 found! Installing thingsboard ... Error: Could not find or
load main class Files\thingsboard\lib\thingsboard.jar ThingsBoard
installation failed!
I assumed it was reading the BASE file directory incorrectly. So I it to the absolute directory location as shown below:
SET BASE="C:\Program Files\thingsboard"
SET LOADER_PATH=%BASE%\conf,%BASE%\extensions
SET SQL_DATA_FOLDER=%BASE%\data\sql
SET jarfile=%BASE%\lib\thingsboard.jar
SET installDir=%BASE%\data
I get the following error:

CurrentVersion Detecting if it is 32 bit machine CurrentVersion 1.8
Java 1.8 found! Installing thingsboard ... Logging system failed to

What am I doing wrong?

The quotes seem to be a problem.
C:\ Program Files\thingsboard\conf\"C:\Program
Files\thingsboard"\logs\install.log java.io.FileNotFoundException:
"C:\Program Files\thingsboard"\logs\install.log
Have you tried to use SET BASE=%ProgramFiles%\thingsboard or escape the space in the path with a ^ SET BASE=C:\Program^ Files\thingsboard?
edit:
The problem is because of the space in the install dir.
I have tried to install it in "c:\test folder" and got the same problem.
There was no problem when installing in a folder without space like "c:\test"
I changed the following part in the install.bat file and was able to install it in the folder with a space.
SET "BASE=%~dp0"
SET "LOADER_PATH=%BASE%conf,%BASE%extensions"
SET "SQL_DATA_FOLDER=%BASE%data\sql"
SET "jarfile=%BASE%lib\thingsboard.jar"
SET "installDir=%BASE%data"

if errorlevel 1 (
#echo ThingsBoard installation failed!
POPD
exit /b %errorlevel%
)
POPD

When I received this error, I ran the command with Run as Administrator and my problem was solved.
if you receive the same result:
Install JRE
Delete the space in the installation directory

Eclipse Neon won't start due to Provisioning exception

I am having problems starting the standard Eclipse Neon IDE. I am running Eclipse Neon 1 with Java jdk 1.8.0. After rebooting my computer, Eclipse won't start (no new plugins / software were install during last usage). I tried deleting everything in .metadata/.plugins/ per this question but it still won't start up. Please help.
P.S. the date of the log seems to be off; I am not sure why but this is the only !SESSION in this log file.
Here is a partial copy of the .metadata/.log file.

Update
After opening the CMD with Administrator privilege and running either
> java -version
or
> java
both responded with
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object
So I guess that something is wrong with my java installation, not eclipse.

There might be several problems for eclipse to fail on start but in you case this ProvisionException occurs may be because of the you didn't cleared proxy or your network connection is set to Ditect it should be Native. And also check SSH certificates
C:\Program Files\Java\jdk1.6.0_45\jre\lib\security
if not found then get it. Please check once you are running eclipse having same architecture means on 32-bit jdk there should be 32-bit eclipse or it won't work.
If you have more than one jre then check eclipse referring to which one. Hope this will help you.

Solved. The problem was with my java installation.
First, I try changing the system environment variable path to only
C:\Program Files\Java\jre1.8.0_131\bin;
This failed, resulting in the same java error message. Then I 'reverted' to an older java installation changing both JAVA_HOME and path to
C:\Program Files\Java\jdk1.8.0_102\bin;
This works fine and solves the problem.
For reference, these links also helped me.

How do I make Java see that it's there? I'm trying to run ng-nailgun but the instructions on nailgun quickstart don't seem to relate to the Ubuntu sudo apt-get install nailgun.
I installed ant, nailgun, and maven2 in the hopes that their dependencies would install whatever java stuff I need. This is on a 64-bit EC2 prebuild of Ubuntu 12.04.1.

error after sofware upgrade with eclipse

I recently updated some of the addons for eclipse (3.7). To do so, I started eclipse with sudo (as not doing so caused some errors while installing new Software earlier). Now I get an error immediatly before the splash screen would appear when I start eclipse without using sudo:
!ENTRY org.eclipse.equinox.launcher 4 0 2012-09-20 12:27:48.447

I do not get this error when I start eclipse with "sudo eclipse". Any suggestions on how to solve this issue? I am using Ubuntu 11.04.

A wild guess. This could be permission issue.
Did you give permissions to the folders as a sudo. Please right click and see the properties of the files in org.eclipse.core.runtime.adaptor.EclipseStarter
And give the read and execute permissions and try. Hope this may help.

While you were "sudo"ing, you may have changed ownership of the files so that you can no longer read them as you. In a command window cd to you install and type:
ls -al
If the owner is root, then you will need to change it back to you. To do this you really need to know your group. It could be your username, the word "staff", "user" etc. To find out for sure, just do that same ls command in your home directory. If you need to change the owners, then type:
sudo chown -R yourUserName.yourUserGroup *
On some unix systems it is "yourUserName:yourUserGroup". Then try eclipse.

How to run Eclipse 3.4.1 on MacOS 10.5.6?

I am trying to run Eclipse 3.4.1 on MacOS 10.5.6?
I think I am using java 1.5 when I run eclipse:
$ which java
/usr/bin/java
$ java -version
java version "1.5.0_16"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-b06-284)
Java HotSpot(TM) Client VM (build 1.5.0_16-133, mixed mode, sharing)
And then I click eclipse icon.
In the Preferences->Java->Installed JREs, I did click 'JVM 1.6.0', since I needs to use 1.6 for my project.
But in the .log file, I am getting these errors, why there is class file bad version number? And how can I fix it?

Eclipse on Mac OS X on Intels only works with JDK 5 (it's horrible). I always have to create two versions of my plugins.
However, it seems that the Android editor plugin that you're using was compiled against 1.6, so I'm not sure that there's a solution...

Take a look at this line:
java.lang.UnsupportedClassVersionError: Bad version number in .class file
That error means that you're attempting to execute bytecode in a JRE that is older than the JDK you used to compile. In your case, the version 5 JRE doesn't recognise the file magic added by the v6 JDK and quits before it hits bytecode it can't understand.
The solution to this is to either specify a target version for the compiler, or upgrade your JRE.

You will need to install java 6 on to your Mac if you want to 1.6 in your project. You should be able to get java 6 here:
http://developer.apple.com/java/download/

I was able to get Eclipse 3.5M5 to run with JDK 1.6.0 as its base VM with a slightly modified path from above:
./eclipse -vm
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0
Better, I was able to put it in the eclipse.ini file in /Applications/eclipse3.5/Eclipse.app/Contents/MacOS, so long as it went above the '-vmargs'. For example:
-startup
../../../plugins/org.eclipse.equinox.launcher_1.0.200.v20090128-1500.jar
--launcher.library
../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx.x86_64_1.0.0.v20081125-1800
-vm
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0
-showsplash
org.eclipse.platform
-vmargs
...

You can try the latest Galileo (Eclipse 3.5) milestone. It is not very stable, but it will run on Apple's JDK 1.6. Get it here (3.5M4 is the latest). Make sure you get the cocoa 64 bit version.
Start it with -vm /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Commands/java
Again, an early beta with all implications.
