I did some tests with new Extension Version "ooeportoinstaller_v1_0_2.oxt", results with "LibreOffice 3.6.5.2 " German UI/ German Locale [Build-ID: 5b93205] {pull date 2013-01-18} on German WIN7 Home Premium (64bit) and AOOo 3.4.1 LibO: "Does nothing" of Version 1.0.1 replaced by CRASH AOOo: CRASH
NOTOURBUG Deutsche Post states this is compatible with OpenOfficeTM 3.3.0 und 3.4.0. Nothing we can do about this.
