Unable to get any SDK examples working [7.6.6]

Same problem with during opening Designer:
[color=#FF0000]Error launching application:
Exception: Error unpacking
componentexample-designer.jar
[/color]
Regarding your checks:

  1. What version of Java are you running?
    Java version “1.6.0_45”
  2. Are there any more details in that error message?
    No more detail, pop-up during opening Designer.
  3. What does your pack200.properties file look like in your SDK’s build directory?
    [color=#800080]modificationtime=latest
    stripdebug=false
    deflatehint=true
    keepfileorder=false
    unknownattribute=error
    segmentlimit=-1
    effort=7
    [/color]

    I try with and without the lines
    [color=#800080]com.sun.java.util.jar.pack.package.majver=150
    com.sun.java.util.jar.pack.package.minver=7[/color]

(see built.txt)
Same Error.
