Could not load library msvcrt-ruby240.dll

[FR4N7Z]

I have install the last version of the x86 version of vim 8 and I have an issue whith the ruby integration.
My plugins like LustyExplorer can’t work and when I enter

:ruby –version
I got the following error :

E370: Could not load library msvcrt-ruby240.dll
E266 : Sorry, this command is disabled, the Ruby Library could not be loaded.
When I run

:version
I have : +ruby/dyn and

-DDYNAMIC_RUBY -DDYNAMIC_RUBY_VER=24 -
DDYNAMIC_RUBY_DLL="msvcrt-ruby240.dll"
Ruby is install in C:\Ruby24 and the bin folder containing the msvcrt-ruby240.dll is in %PATH%.
I also tried to put in my vimrc file

set rubydll="C:\Ruby24\bin\msvcrt-ruby240.dll"
but I got the following error :

E370: Could not load Library
E266 : Sorry, this command is disabled, the Ruby Library could not be loaded.
Both ruby and vim are x86.

I am working on windows 10. Thanks for your help.

Please try updating the PATH as I wrote in vim/vim-win32-installer#47.
It might be better to update the document something like this:

--- a/runtime/doc/if_ruby.txt
+++ b/runtime/doc/if_ruby.txt

:ruby –version

If you want to see the version of if_ruby, use :ruby print RUBY_VERSION. (See :help :ruby.)

set rubydll="C:\Ruby24\bin\msvcrt-ruby240.dll"

This won't work as you expected. " is a start of a comment, so this makes 'rubydll' empty.
(See :help option-backslash.)

Add C:\Ruby24\bin\ruby_builtin_dlls to the PATH solve the issue.
Thank you.
