IcedTea-Web does not start downloaded application in Windows 10 Pro

Hi,

I have been using IcedTea-Web v1.8.8 64 bit to launch a .jnlp application downloaded from a server to establish a remote session to this server.

However when I double click on the .jnlp application IcedTea-Web starts but then displays this message:

'C:\users\[usrname]\.config\icedtea-web\security\trusted.cacerts (Acess is denied)' during operation 'load keystore' C:\users\[usrname]\.config\icedtea-web\security\trusted.cacerts.
Attempts to unlock: 1
Enter type correct password or press Ok or press Cancel to continue without verifying the Certificate.

Clicking Ok or Cancel does not work. I see the same issue with older versions of IcedTea-Web.

I tried also OpenWebStart and after running the OpenWebStart configuration tool with administrative privileges that worked fine.

I assume this issue happens because of how our Windows clients are set up in the company I work for.

I tried to change how javaws.exe is launched by using the rcedit tool from

https://github.com/electron/rcedit/releases

but that did not work as the tool couldn't change the privileges.

Please advise how I can run a .jnlp file with IcedTea-Web with local administrative privileges.

Thank you!
