#7 Cannot complete EclipseNSIS Wizard

[alejandro]

Dear friends,

I have just tried to create an installer using NSIS wizard, but I am unable to finish it. I have tried different options (with/without template, adding files/filesets, saving the output file in the workspace/filesystem...) but, in the end, it always shows an error window without message (please, see attached screenshot). Is there something I can do? If there was some kind of log file that I could send to you, it would be great (but I have not found anything).

My system information is the following:

Computer: Windows 7 Pro 32 bit, spanish.
Eclipse: Luna 4.4.1 for C/C++ Developers.
Version 0.9.8.1 of Eclipse NSIS, Eclipse NSIS InstallOptions Editor and Eclipse NSIS Sources.
Version 0.9.3 of EclipseNSIS Utilities.
Versions 3.9.101.xxx and 1.5.101.xxx of GEF packages.

By the way, I am trying to upgrade to NSIS 3.0b1 but I get this error: "Installer integrity check has failed". That's why I am trying to use this older version.

Any help would be very appreciated.
Best regards,
Alejandro
