ruby : 1.8.7

I have installed xls_export plugin for redmine, but every time I try exporting an Excel sheet of Issue list, I get the following error:

Ok, please supply me with a gist.github.com (sample file and a testscript) so I can test on my Linux. What OS do you use? The testscript has to be independent of any other third-party Software.

This issue occurred Windows 7 only. The plugin works well on CentOS 6.0 with ruby 1.9.3 and redmine 2.0.3.

Ok, then this may be an Windows-Only issue.
