sketch not running: java.util.prefs.WindowsPreferences <init> WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs

in Integration and Hardware • 4 months ago

Dear all,

I've just installed processing onto my new windows 8 laptop and trying to run a sketch. I get the following error in the debug window:

target FRAME_RATE:24

02-Jun-2013 21:57:01 java.util.prefs.WindowsPreferences <init>

WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.

Now it looks like we can't create keys in regedit. Another post you had suggests creating a dummy key in regedit in the java//util//prefs.

Is this correct?.. How do we create a key, what values do we put into it? Because I tried doing as suggested and creating a key with no value in this address.

Or do we change Java application to have rights to create/change keys at this location? If so, how do we do this?

Thanks,

Please, read the section descriptions attentively. Share you Work is to show your code, not to ask questions. Moved.

Indeed, there is a recent similar topic, it seems you found it. On my system, there is no value at this path, just the Processing key.
Perhaps try to run Processing.exe in administrator mode?
