Access denied to the Library DLL

[eriksonssilva]

Hello all!
First of all, thanks in advance for any help provided!
I've started learning coding not a long while ago, but I always try a lot before seeking help other than google...
Today, I came across this: I have made a really simple tool to communicate with arduino, and in my PC it works flawlessly!
However in a friend's PC, it is not working...
He stated that he coudn't even load it...
Once I asked him to run "java -jar" in the file directory, we came across this:

`C:\Users\User\Desktop\Editor>java -jar user.jar

Then I thought it could be related to privilege issues.
But I have run the program successfuly in a non-admin account...
I have searched on the internet and there is an info saying that some times windows will simply deny some permissions. While that's totally understandable , since windows messes a lot with this kind of stuff, I did not find any workaround for this issue, unfortunately.
We both use windows 7 professional, 64bits, if that's relevant.
I hope I have put all the needed info!
Thanks for your attention
cheers!

Please try again with the latest version of the library (lots of Windows updates) and let me know whether it works for you. If not, please verify that C:\Users\User\AppData\Local\Temp\xxxx-jSerialComm.dll file actually exists when trying to run the program. If not, then there is some problem with the library unpacking the native Windows DLL to your temporary directory.
