I just installed the new Windows 7, just to try and see if it is ready to replace my old XP. So far, I still don’t know how to disable the mouse acceleration (not speed)… anyway.
So I am in France, but use my OS and software in English. For some unknown reason, Flash Builder decided that I should use French language (OS location maybe), even though I choose English in the installer ! Thank you very much Adobe, but please let me choose my language in the future.
As you can imagine, no way to change the language, even reinstalling doesn’t help.
But… good news everyone ! There is a fix. Edit your eclipse.ini and add “-Duser.language=en” somewhere after “-vmarg”.
For exemple, I use the Eclipse 3.5.1 and my eclipse.ini looks like this :
-data
X:/wb_3.5.1
-showlocation
-showsplash
org.eclipse.platform
–launcher.XXMaxPermSize
384M
-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
–launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
-vm
C:/Program Files (x86)/Java/jdk1.6.0_18/jre/bin/client/jvm.dll
-vmargs
-Duser.language=en
-Dosgi.requiredJavaVersion=1.5
-Xms128m
-Xmx384m
-Xss4m
-XX:PermSize=128m
-XX:MaxPermSize=384m
-XX:CompileThreshold=5
-XX:MaxGCPauseMillis=10
-XX:MaxHeapFreeRatio=70
-XX:+UseConcMarkSweepGC
-XX:+CMSIncrementalMode
-XX:+CMSIncrementalPacing
Hope that helps.

thank you for this very helpfull I was struggeling with this for some time thanks to adobe imposing my danish language on me
Thanks for this easy tricks. I was in the same situation, french developper prefering English in my tools, I’ve switch back to Shakespeare language
This doesn’t work for standalone Flash Builder…
I am using russian Windows XP SP3, but want to see english runtime error messages. Could it be FlashPlayer language issue not FlashBuilder itself?
