Since yesterday (I think) I am unable to create a new Java application in NetBeans 8.1. It gives the error: "Project folder is not a valid path"
But that is nonsense.

Yesterday evening NetBeans suddenly appeared not to be functioning anymore, but after a while everything seemed normal again. So I have no idea what might have happened.
I could not find any useful info on the internet either. Does anyone know what might be the problem and/or knows a cure?

If all else fails, I will uninstall NetBeans and download 8.2.

Thanks upfront!

Hi Piet,

I've heard about other users having problems with NetBeans 8.1 recently. I think your best course of action is to upgrade.

hi Stephan

thanks for your reply.

I created manually a new project folder, and then I could create, in NetBeans, that new project. But it suddenly seems to be unable to create such a folder by itself. I checked whether the privileges of the users for writing to the drive had changed suddenly, but I don't see anything unusual (not that I'm an expert in these thing though).

Well, I've been using NetBens 8.1 for more than a year now, without problems, so this is very strange.

But indeed, I think I will follow your advice and download 8.2.

I'll let you know.

It's possible that an update to your OS caused something to stop working.

Now that you mention it: there was indeed an automatic Windows 10 update this week. But how to check if that caused any problems? And if so, is that only related to NetBeans? I have not encountered any other problems so far.

Well, if you *really* want to know, you can try rolling your updates back to last week.

It would be too much of a bother for me though. If updating NetBeans works, I wouldn't break my head over it.

When installing NetBeans 8.2, it gives me the error:

'the specified installation folder canot be canonized' (that folder being 'C:\Program Files\NetBeans 8.2', but any other folder gives the same message).).

There is also an exception reported on the next line:

Exception:
java.io.IOException:
No More files ("er zijn geen bestanden meer")

This is maddening! Anyone knows what might be the problem?

You might try uninstalling Java completely, and installing the latest version of the JDK before attempting to run the NetBeans installer. You might want to try cleaning up your environment variables as well.

Solved it, but what a nightmare....

At first I followed Stephans advice: uninstalled Java and NetBeans (many versions, collected over the past few years), and cleaned up my system variables.
Then installation of Java 8.131 went smooth (wel I think it did). However, with NetBeans I kept getting this error:



(by the way: Sylvia is my wife, it is her laptop officially)

It was maddening, and searching the internet for this 'canonized' was without any success.
It was only after I made a screenshot of this error and tried to save it via Windows Paint, that I got this "io exception: no more files" too that I started searching for this error.
And that helped. See for instance:this site

It seems to be related to what is called the "Asus Data Security Manager". My (wife's) laptop is indeed an Asus, and I followed what that site said: remove this ADSM via the windows add/remove software, and what a relieve: I could suddenly save this error-picture and, best of all, my NetBeans is installed and running!

I really don't know why this error suddenly popped up, or how long it has been going on. Maybe since the latest Windows update from a few days ago?

I hope that this reply helps someone facing the same problem.

And Stephan, a cow for all your help!

I'm glad you managed to sort it out. Thanks for the cow, and have one in return for getting back to us with an answer that will help users with similar issues.
 
It is sorta covered in the JavaRanch Style Guide.
