I have uninstalled netbeans 8 and installed 7.0.1 version. After Installation when I open it the screen says "Loading cached modules" and closes automatically, No error shown.
I tried deleting the folder in user/appdata/local/netbeans but yet it didn't work (Netbeans 7.1 won't open).
Running Win 7 64
Check Which Java version you used ? if Java 8, uninstall and install Java 7 then try.

I wanted to update Netbeans and I tried to uninstall Netbeans 11.3, but I
couldn't, I got the same error mentioned above, fix it as follows

I have downloaded the eclipse ZIP folder in my system(windows 10 64 bit) , copy paste it in C:/ drive and clicked the eclipse icon. It shows an error " An error has occured, please refer to the log file" . I had tried deleting .metadata folder , running command "eclipse -clean" in CMD.
In my system java 11.0.8 has installed. I checked java version it is 64bit and compiled and executed a small program through CMD , it was working fine. I have tried every method but didn't get the solution. The log file link of WriteXo is below. Please help.

The log says you have Eclipse Neon.3 (4.6.3) (eclipse.buildId=4.6.3.M20170301-0400), not Eclipse 2019-09 (4.13), which is too old to work with Java 11 (java.version=11.0.8). The current Eclipse version is 2020-06 (4.16) and works with Java 8 and higher (including Java 11).
Don't try to run a 6 year old eclipse on a 6 month old JVM.
This is effectively a bug in JDK14 (but an intentional one, and introduced in JDK version 10). Eclipse has worked around this bug since mid 2016, so the solution would appear to be: Download the eclipse offered on eclipse.org right now, and this problem will go away. Alternatively, download a JDK8, for example from adoptopenjdk.net and run it on that.
I'm encountering a problem by trying to use NetBeans 8.2 under Mac Os High Sierra. I'm trying to create a new project but nothing happens.
So after few search over the web I seem to understand that my problem is my actual version of Java JDK which is 11.0.
Unfortunately I dont know how to switch my actual version to an earlier one JDK 8.0 which seems to be the one to use for netbean 8.2 ! :/
If anyone knows how to help me I would be really greatful ! :P

There are two steps involved in getting NetBeans 8.2 to work:
Download and install JDK 1.8 if it is not already on your machine:
This answer describes how to do that for openjdk 1.8 on High Sierra.
Alternatively, you can download Oracle JDK 1.8. The installation instructions are here.
Once JDK 1.8 is installed, update the file netbeans.conf:
Locate file netbeans.conf within the etc directory under the NetBeans installation directory.
It is a text file containing name/value property pairs. Open it in any text editor.
One of the properties it might specify is the path to the default JDK to be used via property netbeans_jdkhome. Therefore locate the line containing the text netbeans_jdkhome.
If line is commented by starting with the # character then delete that character.
In the unlikely event that the property does not exist in the file at all, just insert it at the end of the file.
The property's value should be the path to your JDK 1.8 installation.
In my NetBeans 8.2 installation my entry looks like this netbeans_jdkhome="C:\Java\jdk1.8.0_181", though obviously your path will be different.
Save your change to netbeans.conf and restart Netbeans. Your issue should be resolved.
Alternatively, if you would prefer to use JDK 11, you could take a completely different approach:
Download and install Apache NetBeans 10.0 which supports JDK 11.
Since you already have JDK 11 installed, NetBeans should work immediately.
Notes:
With NetBeans 10.0, individual projects can be configured to use JDK 8, 9, 10 or 11, provided that:
The corresponding JDK is installed on your machine.
The corresponding JDK is also added as a Java Platform within NetBeans (using Tools > Java Platforms > Add Platform...).
On NetBeans 8.2 you cannot use any JDK version > 8.
You can safely install both NetBeans 8.2 and NetBeans 10.0, and even run both instances concurrently. They do not impact each other in any way, though obviously you should not open a project in both instances of NetBeans at the same time.
I had netbeans 8.1 installed on my PC (windows 8.1) with JDK version 8. I uninstalled netbeans 8.1 and then installed netbeans 8.2. After installation I ran it and everything worked fine.
After installing netbeans 8.1, I uninstalled JDK 8 and then installed JDK 9.
After installing JDK 9, when I tried to run NetBeans again, it gave me error that
Java SE Development Kit not found on this computer
I looked it up on the internet and came to know that cause of this error was that when NetBeans 8.2 was installed with JDK version 8, NetBeans was configured to use JDK 8. So when JDK 9 was installed, NetBeans couldn't find the JDK 8 which it was configured to use by default and hence this error was thrown.
I then uninstalled NetBeans again and then when I tried to run its setup again, it gave me the same error. Now I can't even run the NetBeans setup.
Can someone suggest a solution to this problem?
PS. I have already added JDK 9 to environment path variable.
So after some searching i have come to know that for netbeans 8.2, you need JDK 8 because JDK 8 is required to use JavaFX 8 features in NetBeans IDE 8.2.
After installing JDK 8, Problem was fixed.
I can install the JRE 7 without any problem. However when I try to install JDK 7, nothing happens. I am currently running Win7 64-bit. When I double click on the downloaded file, a dialog box pops up asking me if I want to run the application, I click "run" and then nothing happens. I don't even get an error message. JDK 6 installs just fine. I tried uninstalling all versions of Java, and the installing JDK 7, but the same thing happens. I've even installed JDK 7 on another computer just fine, and then used that file to try and install on my laptop, but the same thing happens.
Any ideas?
Later, pre-release versions of the installer such as 7u6 do not have this problem.
Download pre-prerelease versions here: http://jdk7.java.net/download.html

The Oracle bug report details how to fix this:
(I've modified it to use the latest stable version (u05)
Suggested Workaround:
For Win7, here were the steps used to get it to
install based on the above instructions.
1) goto c:\Users[your user]
2) create jdk1.7.0_05_combo directory
3) right click on folder and select permissions
4) click advanced button
5) deny delete/delete sub for each listed role/user
6) run downloader installer
7) goto jdk1.7.0_05 and run the java_jdk.exe (no need to copy to another dir)
