Netbeans 8.2 uninstall in Windows 10

I have tried to uninstall Netbeans from control panel, but when I try to remove it, this pops out "JDK not found on your computer" https://imgur.com/a/KQfrG , but Netbeans is working perfectly, my JAVA_HOME and Path have the right paths. I tried to launch the installer, maybe it would change the "uninstall.exe", but it didn't do anything. When I execute uninstall.exe, it doesn't create a log file in .nbi/log, I have there just the installation and logs for the times I tried to reinstall in hope for "repair"

Eclipse editor runs slow on Ubuntu 16.04 after first project build

I've recently installed Ubuntu (16.04) I've noticed that after the first build of a project on Eclipse (I've tried this with Luna and Mars) that the editor starts to run slow. There is a noticeable lag when typing and selecting text etc. It doesn't make it unusable, but it is fairly irritating. I've done the following to try and fix this, but to no avail:
allocate more memory in eclipse.ini
set the environment variable $SWT_GTK3=0 (as I found something that said there may be a gtk3 bug in 16.04.
update graphics drivers
At this point I'm really not sure what else to do. It seems to run well at first, but after that first build (Java) it just dies a bit. Any suggestions on what I could do to try and fix this would be much appreciated!
It's the first time I've used Eclipse with Ubuntu, as normally I'm on a Windows machine, so I'm not sure if maybe I've just not set something up properly.

add the below lines into the eclipse.ini file:
--launcher.GTK_version
2
before the line:
--launcher.appendVmargs

Eclipse opens and then immediately closes after graphic appears

When windows installed updates, it closed my eclipse and corrupted the workspace or something. When I try to start eclipse I get the error:
I have already tried most of the google solutions. I tried deleting the plugins folder, and it still does the same thing. I tried adding the --clean option to the eclipse launcher, and it still crashes. If I delete the org.eclipse.e4.workbench folder, it still does the same behavior. When I try to start eclipse it shows the launcher logo for about a quarter second, and none of the above solutions fixed my problem.
Any other ideas?
Thanks,
The workspace exited with unsaved changes in the previous session; refreshing workspace to recover changes.

Just Uninstall the latest Java updates from ControlPanel->Programs and Features
and Re-Open Eclipse .

SOLUTION IS SIMPLE
Firstly you wil come across this issue if you have uninstalled Java versions from system uninstall window. eg., I uninstalled Java 8 u151 from my machine and downloaded and installed Java 8 u152. Then it was opening with splash screens for few seconds.
Quick Fix is:
Undo all your java version changes.
Uninstall 152 for exammple and install the original 151 version. This fixed my issue.
DONT FOGET TO COPY ECLIPSE folder TO c:\program files folder.

Unable to install new software/check for updates eclipse

I'm trying to install subclipse on my desktop so i can use subversion.
When I was at school with my laptop, the installation worked well and i was able to update and commit on the subversion, but, while i was at home, i tried to update and nothing worked. Then I tried on my desktop to install the subclipse plugin without success.
When I go to "Help>install new software>Work With Kepler - http://download.eclipse.org/releases/kepler"
Nothing appears on the software view except "pending..."
The thing I don't understand is that i'm not using a proxy at home, so i don't understand why it's freezing at this step.
Then, I tried to change my eclipse version but it didn't worked
I also tried to change my network settings without success
Anyone had the same problem before or know how to fix it ?
EDIT 1 : While waiting for the pending thing to resolv i had an error :
"Unable to read repository at http: //download.eclipse.org/releases/kepler/content.xml.
Unable to read repository at http: //download.eclipse.org/releases/kepler/content.xml.
Connection has been shut down"

I solved a similar issue today with a new eclipse Kepler installation on a machine with Java 7. We eventually got it to work by having eclipse run on a Java 6 JRE instead.
To do this, add
-vm
C:\Program Files\Java\jre6\bin\javaw.exe
Above the -vmargs line in your eclipse.ini file (which should be next to your eclipse.exe)

Looks like you have extra whitespace between : and /

Installed Eclipse, but it won't start

My Eclipse Kepler had been running just fine until I messed up some settings and then had to delete the installation directory and re-extract the zip file. I also deleted the workspaces.
But after I had extracted the zip file, the Eclipse just won't start.
I tried extracting to another drive (C:) this time, still won't start.
Also tried the -clean option, but to no avail.
What went wrong?

There are few things I could think of that are trivial, but might solve your problem. Maybe you changed JAVA_HOME in Path, or deleted it. Check for Environment Variables for JAVA_HOME.
Another thing is that you have Java 6 and you need Java 7. Or in your case, you need Java 7 x64. Maybe you have installed Java 7 x64, but JAVA_HOME points to another version of Java. Check for that too.
Ultimate solution is to write in eclipse.ini argument for desired virtual machine path, like:
-vm
/path/to/desired/java/vm

You can start eclipse with debug / console flag and see exactly what is happening

Run eclipsec.exe this will launch Eclipse with a debug console in the background.
