Can't open JNLP after changing to windows 10

Question

I have a problem where I can't open up .jnlp files. I see the java web start is running in the task manager but nothing appears. I had tried to reinstall java clear temp appdata software disruption and cache and turned off firewall and antivirus but that didn't solved it.

I also tried to run it on another Windows 10 machine and there it would run perfectly. Does anyone know how I might be able to fix it?

My Java version is 8 update 101.

Answer 1

so it was the antivirus even after i turned it off it blocked the jnlp

and also it had been downgraded to a (free version) after the upgradeing to win 10 but after I reinstalled avast to the protection suit it worked again

Answer 2

Had this issue with an associate at my company. The problem was that the .jnlp application was only trying to open in IE instead of the Javaws aplication.

What I did was right click on the file > Open with > Browse > C:\Program Files (x86)\Java\jre1.8.0_221\bin\javaws

I also marked a check by the box that said set this as default app. The issue no longer affects us

Answer 3

locate the .jnlp file. right click and select "open with" ..then browse to a java program that will open it. I had this problem with marketcaster.jnlp with different browsers and this corrected it.

Answer 4

I had a problem opening a jnlp file, no matter what, trying to associate it with the Java Web Service exe javaws.exe, but it just would not associate and would not be run. I read throughout forums and all, and in the end from old DOS.exe files that I have used, somehow I did that and a miracle, it worked, I simply dragged the saved jnlp file and dropped it onto the javaws.exe, and it was executed. wanted to share this...

Answer 5

JRE 32 bit was causing issue for me . I uninstalled it and installed 64 bit JRE , JNLP files opened on all browsers. I think the browser n JRE must be both same 32 bit or 64 bit. Mismatch leads to this issue, not sure though.
