Hi Bogdan, First of all, thanks for all the efforts you're undertaking here!
Second, I think your conclusion of blaming Win32.pm might be a red herring. The reason for including the newer version is quite simple - one of the functions we use it for is to determine the actual version of Windows it is running on. This is used in our Support Module. I added support for detecting Windows 2012 Server and Windows 8, this was introduced in version 0.46. The full list of changes is found on CPAN; you can also use metacpan to make diffs between releases. Unfortunately there are lots of whitespace changes in one of the releases so not all is fully trackable, but all the changes seem not to have much impact. https://metacpan.org/release/JDB/Win32-0.47 If you want to install a different version of Win32 you can install it like this: cpan JDB/Win32-0.43.tar.gz Please note that this only works if you have installed OTRS in a path without spaces, i.e. not in C:\Program Files, but in d:\Helpdesk would work. Again, if the Win32 change would be the culprit, this would be super but I have my doubts. The Version.pm that you found introduced in OTRS was because we started using Encode::Locale to fix encoding issues for command line utilities, and they require Version.pm which is core, but only in perl 5.10 and later. For the 2.4.9 version you tested I basically took the Perl and Apache versions of an old, stable installer and put them into the new one. BTW other people stated that for *them* the 2.4.9 actually works. Was one of the versions of OTRS on Windows for you really stable? In my experience the mod_perl based ones are generally stable, but sometimes the web server restarts. This could be as simple as the worker restarting (see the setting in the apache config). The last version of the windows installer also stops, and you'd have to start it manually, of course this is NOT desired and I'd like to learn why this is and what we could do about it. If there was a version that did work for you, can you use THAT one, and replace the OTRS with 3.2.8 and see if THAT is stable? It *could* be we simply introduced breakage by accident in the OTRS code base. The best results on WIndows I found are when you install ActiveState perl (x86) which comes with PerlEx, and you use Microsoft IIS as the web server. This is also what the 'new' beta installer advertises.
