I'm getting a java.lang.UnsatisfiedLinkError from java.lang.ClassLoader$NativeLibrary.load() with the message "Access is denied". The DLL is being loaded from a network share via a UNC path. It previously worked without error on other network shares (I have been told by a sysadmin that this particular share is more "natively Windows"), so my first instinct was to use cacls to grant Full Control on the DLL file both for Everyone and the specific user running the Java code. When I view the DLL Properties in Windows Explorer, it clearly has those permissions set, and yet it is still failing with this error. Any ideas?
One possibility is that this dll is, in turn, trying to load other dlls, which have not been given sufficient permissions.
Run it as System Administrator and it will work for sure. I had a same problem and ran the Eclipse as Administrator and it worked.

I tried the other solutions but they didn't worked, so please don't just say "It's a duplicated so now you have to open this link." Because I tried them.
I have Windows 8.1 and I installed Java 8 JDK some days ago, now I unistalled it because I've had some problems with it (like the PATH for cmd was not set), and after unistalling it I tried to open the Java installer, after the UAC popup nothing happen. I tried opening the installer "sandboxed" with the program "Sandboxie", the Installer opened 2 services, after a few seconds another service opened and then every service closed.
I have no error, no logs, nothing.
P.S.
I tried downloading again the installer 3 times, nothing changed.
Edit:
JRE Installer doesn't start either.
Edit:
I'm actually in safe mode with internet connection and the installer still don't want to run... I don't know what to do now...
I tried with "sfc /scannow" and it said there was no problem, I tried "DISM.exe /Online /Cleanup-image /Restorehealth" too, no problem got reported.
Edit:
I tried running the installer with a Guest account, nothing changed. Anyway I found a solution.
I searched for everything that contains "Java" in C:\ and I found some value (that could have prevented Java Installer from running because it thought Java was already installed), I deleted them (carefully, don't just delete everything on your computer, that's not the way.)
Now I tried launching the installer and.. Here we go! Finally I can install it.
Thanks to anyone who tried to help me, I appreciate it.
In my case problem was in C:/Users folder. Initially my OS language was not English, after changing, it causes some errors. I couldn't install jdk, couldn't run some desktop tools. After looking for the solution, I could found it. My user name in Users folder had non English letters. So, I changed name of user and it solved my problem:

You should add java in Path:
Open the System Properties.
Find the Advanced Tab in the Properties Window. Click Environmental Variables.
Scroll down in the System variables and find the PATH variable.
Select the PATH variable and click the Edit button.
Add the Java installation path to the PATH variable (dir_java/bin)
And also create system variable JAVA_HOME
What antivirus are you using?
If your av has some kind of process viewer that you can use to see when it starts and when it terminates and if it is marked a suspicious. Here is a screenshot from my av. I use comodo image here
If your av doesn't have this feature, try turning it off during the installation. Remember to turn it back on after you're done
This morning when I was trying to load IntellJ it doesn't boot up. I see idea.exe under process tab. When I tried to run idea.bat from command line, I get the following:
Invalid Log Path: Log path 'Ç:\Users\NAME.IdeaIC2016.3\system\log' is inaccessible. If you have modified the idea.log.path property please make sure it is correct otherwise please re-install the IDE.
Check folder permissions, it may be owned by admin for some reason. Try removing this folder so that IDEA creates it again.
Run disk tool with permissions fix.

I'm going to develop a java web start application, which need to access protected system directory and install a program there.
I know, how to exit sandbox, my application is signed and have access to filesystem. The problem is, that it sill can't access directories like C:/windows/system32.
I found solutions for standalone java applications:
Java: run as administrator
How to do this in java web start?
Thanks in advance for answer!
In your case you can probably try to use the following trick:
Precompile a jar file with the Manifest pointing to the main
class, that carries out all of the required filesystem routines
Put this jar somewhere into the resources folder of your Web-Start
application and then copy it into the user's Temp folder upon
Web-Start execution
Provision required files from the elevation
PowerToys
in the similar manner
Call " %PATH_TO_USER_TEMP%/elevate"
command together with "java -jar %PATH_TO_USER_TEMP%/yourJar.jar"
(please refer to the article above or additional documentation on
the Elevation PowerToys to find out the details)
If everything
works out, user shall be presented with a request to grant the
executed java process required Admin privileges.
I'm into a very strange issue that's making me crazy .-.
I'm working on a relatively big Java project on Windows, using NetBeans and IzPack to prepare the graphical installation package.
Everything is ok, the compiled installer seems to work and my program is copied in 'C:\Programs\MyProject' folder.
But... when I double click on the myproject.jar in that folder it doesn't start at all. I obviously tried to open a prompt and type 'java -jar myproject.jar' but nothing, not even a line of error code.
The curious facts are two:
if I open it using the prompt with administration rights it works
in the same folder there is another jar, 'uninstaller.jar' created by izpack, and it works with double click.
I double checked my JVM installation, the PATH/JAVA_HOME/... values, and Properties->Security tab of my JAR but the permissions to execute/read/write for every kind of user are ok, and also are equal to the uninstaller.
So what's the problem? Thanks
This is almost certainly caused by Windows UAC on Vista and Windows 7.
Your program is probably trying to write to data files in the same directory as it is installed.
On Windows, well behaved programs write to the users or all users app data directory.
The location of that directory varies depending on the version of Windows.
You can use the system property "user.home" to find a safe place to store data.
You can also get a list of environment variables for shared and per user program data folders from here.
I'm trying to compile a Flex application in Ant (no problems here, I can do it fine). When I try to publish the contents of the project to a Windows network drive (known as "Z:\" on my system), I get the following LAME exception thrown by Java/Ant:
BUILD FAILED
C:\workspace\bkeller\build.xml:42: Failed to copy C:\workspace\bkeller\web\assets\text\biography.html to Z:\web\bkeller\assets\text\biography.html due to java.io.FileNotFoundException Z:\web\bkeller\assets\text\biography.html (The system cannot find the file specified)
Which kind of sucks. I can't find any way to get rid of this problem and it's pretty crucial to my project that I get this working. I know for sure that I have read/write/execute permissions on the network drive, I can create/edit/delete files on the drive just fine through Windows explorer.
Drive Z is a network mount to virtualbox, allowing me to get access to my host OS, Ubuntu. I've double checked that it has write permissions. Any ideas?
Seeing as how Z is a network mount, verifying that it works (e.g. that you can create / write files) through Windows Explorer may not be the same thing as verifying that it works from within Ant:
You may have specified the necessary user / password sometime in the past and Explorer remembered it (so it doesn't ask you again). Ant obviously wouldn't.
Ant may run as a different user, especially if you spawn another process inside the build.
Can you write a simple test in java and see if it can create a file on your Z: drive? Perhaps that'll provide some insight. You can also run ant with -debug switch and see if it provides a more detailed info. At the very least it would print a stack trace and you can download Ant source and see what's happening.
Just experienced the same problem. The copy target was a regular network drive connected to my Windows 7 machine.
I was able to solve the problem by restarting Eclipse.
The cause might have been that Eclipse was running with Administrator privileges because of an Eclipse update I had been performing beforehand.
Does it go without saying that the file actually exists? Regardless, while you may have permission, does the process that is actually running the ant task have permission?
you certainly thought about it, but have you tried
Z:/web/bkeller/assets/text/biography.html
I always use the / instead of \ even on Windows and can't remember having a problem with the Copy target.
It was a problem in VirtualBox's shared folder system. It was fixed a few releases ago by 3.0.X.
