Software error after password change

I used the Foswiki Windows Installation Guide and installed Apache HTTP Server 2.2 and ActivePerl 5.12.1 Build 1201.

In Chapter More Foswiki configuration after clicking change password and save button i got the following software error and I don´t know why:

Can't locate Error.pm in @INC (@INC contains: C:\FOSWIKI\Foswiki\lib . C:/Perl64/site/lib C:/Perl64/lib) at C:\FOSWIKI\Foswiki\lib/Foswiki/Configure/LANGUAGES.pm line 11, <F> line 1361.

Thanks for help in advance.

Edit: I forgot to install error.pm, after installation the problem was solved.
