I'm very sorry but, as you can read, I'm very far from the solution!!!

 

At the moment I need to fix the PPM error

 

Can't locate object method "rvalidate" via package "PPM::XML::PPD::html" at
C:/Program Files/OTRS/StrawberryPerl/perl/site/lib/PPM.pm line 1687, <> line 5.

or the CPAN one

 

... Detected uninstalled Perl.  Trying to continue.
Unable to find a perl 5 (by these names: C:\Program Files\OTRS\StrawberryPerl\perl\bin\perl.exe perl.exe perl5.exe perl5.10.0.exe miniperl.exe, in these dirs: . C:\WINDOWS\system32 C:\WINDOWS C:\WINDOWS\System32\Wbem C:\Program Files\OTRS\StrawberryPerl\perl\bin C:\Program Files\OTRS\StrawberryPerl\perl\bin)
