error with starting Opensim

[Ayman Habib]

Hi Giovanni,

What's the problem are you running into now? please post the messages.log file containing the stack-trace of the crash if you continue to have problems. Removing the .opensim folder as described by Matthias is needed, the registry keeps user preferences across sessions and probably you wouldn't need to change it.

Good luck,
-Ayman

Hi Matthias and Ayman

I'm kinda dummie with this computer stuff, actually.. heheh

I did read both of your replies, but here's the question: "C:/documents and settings" doesn't actually exists in Windows7. So, where's this ".opensim" file?

thanks again

Hi Giovanni,

This looks more like the localization issue described in this trail:
https://simtk.org/forum/message.php?msg_id=1180

which you can fix in Edit->Preferences as described on the trail above.

Can you try that?

HELLO EVERYONE!

what a wonderful day, full of joy and happiness!

I did it! OpenSim is running smoothly here!

I followed the instructions about change the "dot" for "comma" in some preferences, such as background color, marker color, marker display radius and muscle display radius.


So this is it. thanks to everyone who helped me!

best regards,

Giovanni Ferreira
