in reply to Perl libs not found in windows

Many modules are failing with same error while very few succeed.

This is often the result of incorrect installation procedure.

By way of example, if DBD::mysql has been correctly installed then auto/DBD/mysql/mysql.dll should exist in one of the @INC directories that were specified (normally C:/Perl64/site/lib).
That's the "loadable object" that it's looking for, and the error message you got is telling you that it can find no such file.

How did you install DBD::mysql ?
