Qsys - problem witch handling path

Hello.

I have installed Quartus 11.1 on windows 7 in path "C:\Program Files\Altera". After that it showed that qsys can't start. After starting it in console i get exception from Java. Here listing:

C:\Program Files\Altera\quartus\sopc_builder\bin>qsys-edit.exe

Exception in thread "main" java.lang.NoClassDefFoundError: files/altera/quartus/

sopc_builder/model/lib/qsys_startup_screen/png

Caused by: java.lang.ClassNotFoundException: files.altera.quartus.sopc_builder.m

odel.lib.qsys_startup_screen.png

at java.lang.ClassLoader.loadClass(Unknown Source)

Could not find the main class: files/altera/quartus/sopc_builder/model/lib/qsys_

startup_screen.png. Program will exit.

As you can see there is problem witch path. Program can't handle space in it. This is basic problem in windows programming. Probably need to change from '' to "" .Could somebody fix it in nearest future. Please.

I'm trying now to workaround it on my own, but if sombody have some idea I'll be greatfull
