Why at X-OpenOffice.org (or X-LibreOffice) first run an error is shown and the program doesn't start?
The error at OpenOffice.org (or X-LibreOffice) first run is caused by an installation path too long. OpenOffice.org (portable and/or in original form) seems not to support too long paths, therefore, starting X-OpenOffice.org.exe (or X-LibreOffice.exe), the following error or similar ones could appear:
To fix the problem, you have to rename the directory that contains X-OpenOffice.org, i.e. X-OpenOffice.org 3.3.0 [rev18], to X-OOo, or move the program to C:\X-OpenOffice.org, and then restart X-OpenOffice.org.exe
The same problem could happen in a winPenPack installation on too long path. Also in this case it must shorten the path or rename the winPenPack installation folder (for example H:\ or C:\winPenPack).
