|Not a good idea to post your email address on a public forum, spammers will bombard you with spam... remove your email address.|
Also, rather than asking people to contact you for such an issue, why not just post the solution here?
Usually with MSI files you can use a extractor tool, such as 7-Zip to extract the content, i usually do this when i package application i write to ensure all the content has been packaged.
What problem do you think users will have with this extention?
Oh by the way the MSI file can obviously just be double clicked and installed.....
