Having more information would be nice.  Maybe apply the -v option
twice for maximum verbosity.

On the other hand, I have the impression that this error message is
triggered by Windows, hence it's possible that Perl doesn't even
notice that something doesn't work as expected.

I googled for this error message yesterday but didn't find any
solution.  However, an R user obviously had the same problem and he
said that an upgrade to the latest Perl solved the problem for him.
But I doubt that an upgrade helps because he upgraded to Strawberry
Perl 5.12.1 and TL-2011 already has 5.12.3.

It would also be helpful to know whether there is another instance of
Perl installed on the system already.  Someone reported that the error
was caused by an other instance of Perl.  In this case the cause of
the problem was that wrong DLLs were found.  However, the way TeX Live
invokes its own Perl is quite robust.  But it's better to know though.

Anyway, in order to find out whether it's a Perl issue, I copied a
.zip file containing the Perl shipped with TL-2010 to


Erwan, what you can try is to go to the directory tlpkg (in the
installer tree) and uncompress tlperl-TL2010.zip there.  Then rename
the directory tlperl to something else and rename tlperl-TL2010 to

I'm not sure whether the current installer works with an older Perl,
but it would be nice to know whether you get further even if it
crashes with an error message from Perl rather than with "perl.exe has
stopped working", which most likely comes from Windows.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
