charles1990

i can't run any processing code now....even basic examples.. the console say:

Exception in thread "Thread-12" java.lang.NumberFormatException: For input string: ""
    at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)

i was using 3.0.1 on win7

i have uninstalled Java and reinstalled p3 several times...still not working...

and i followed the instruction on https://github.com/processing/processing/wiki/troubleshooting

i deleted the preferences.txt but now i can't open the preference window by going to File->Preference in processing and the console says:

anyone know what to do now??

GoToLoop

• You may try out older versions.
• You may try out 32-bit versions too.
• Don't use Windows' system folders for Processing installations.
• Prefer something like your Documents or some other place under your control.
• Don't forget to whitelist Processing in the firewall.

charles1990

still not running even for the 32bit version....

koogs

That looks like a preference is missing a value.

NumberFormatException...

processing.app.Preferences.getInteger...

A corrupted preferences.txt file?

charles1990

maybe...but how to fix that??

koogs

the troubleshooting suggests that the preferences.txt file will be recreated if you delete it so try that again.

post the recreated preferences.txt file here.

charles1990

i have run p3 several times...the preferences.txt wasn't recreated...no file at the original path...

koogs

here's mine, which was successfully recreated when i just tried it.

NB was recreated on a slightly older version (3.0b7) on linux, so it might not be exactly as needed.

NB replace the value for sketchbook.path.three near the bottom

i created a txt by hand and copied your text...but the same problem still there...same thing in the console...

koogs

Did you try the thing about adding flags to the startup script to create a logfile?

Try that and paste the logfile here

charles1990

haven't try that....can you tell more specifically how to do that,please?? or what webpage i can refer to? thanks for your patience....

koogs

It's the troubleshooting link in your first post.

(it's a good idea if you're posting lists of things or output to format it as code for the forum - highlight and hit ctrl-o. otherwise it gets displayed as one big paragraph and the symbols get translated into markup and it looks a mess)

anyway, nothing looks obviously wrong in the above log, but then i don't know windows 7

is the path really "C:\Users\user..." or have you anonymised it? the classic problem is a space or non-ascii characters in the path...
