Esteban, My computer is using Windows 10.
I'm using the Pharo Launcher 0.2.11-2016.09.22 (as indicated in the README.txt or 3.0.20131220 as indicated in the Control panel's Programs and characteristics). (http://files.pharo.org/platform/launcher/pharo_installer-0.2.11.exe) The image I was using was the latest Pharo 6.0 (Beta) downloaded today. http://files.pharo.org/image/60/latest.zip With that combination I got the crash while trying to run: AthensFlakeDemo new openInWorld. As an additional test, I downloaded the VM version that you included (http://files.pharo.org/get-files/60/pharo-win-latest.zip) with the latest image as of today (60465), but got the following errors: First it complained abut the missing PharoV50.cources, but loaded Pharo. Then I tried to run the demo, but got the following error: Could not find accessor for variable named "aFormat" FFICallout>>loaderForArgNamed: FFICallout>>loaderForArgNamed:indirectIndex: FFICallout>>argName:indirectIndex:type:ptrArity: FFIFunctionParser>>parseArgument FFIFunctionParser>>parseArguments FFIFunctionParser>>parseNamedFunction: FFICalloutMethodBuilder>>parseSignature: FFICalloutMethodBuilder>>generate FFICalloutMethodBuilder>>build: FFICalloutAPI>>function:module: AthensCairoSurface class(Object)>>nbCall: AthensCairoSurface class>>primImage:width:height: AthensCairoSurface class>>extent:format: AthensCairoSurface class>>extent: AthensFlakeDemo>>initialize AthensFlakeDemo class(Behavior)>>new UndefinedObject>>DoIt OpalCompiler>>evaluate RubSmalltalkEditor>>evaluate:andDo: RubSmalltalkEditor>>highlightEvaluateAndDo: [ textMorph textArea editor highlightEvaluateAndDo: arg1 action. textMorph shoutStyler style: textMorph text ] in [ textMorph textArea handleEdit: [ textMorph textArea editor highlightEvaluateAndDo: arg1 action. textMorph shoutStyler style: textMorph text ] ] in GLMMorphicPharoScriptRenderer(GLMMorphicPharoCodeRenderer)>>actOnHighlightAndEvaluate: RubEditingArea(RubAbstractTextArea)>>handleEdit: [ textMorph textArea handleEdit: [ textMorph textArea editor highlightEvaluateAndDo: arg1 action. textMorph shoutStyler style: textMorph text ] ] in GLMMorphicPharoScriptRenderer(GLMMorphicPharoCodeRenderer)>>actOnHighlightAndEvaluate: WorldState>>runStepMethodsIn: WorldMorph>>runStepMethods WorldState>>doOneCycleNowFor: WorldState>>doOneCycleFor: WorldMorph>>doOneCycle WorldMorph class>>doOneCycle [ [ WorldMorph doOneCycle.
