deployment package

I wrote a small vb.net program that uses SMTP to send an email with an attachment each day. After testing to make sure it worked, I added a Deployment Package to the solution and rebuilt it under release mode; 2 projects were built, no errors. I have created deployment packages before with no issues; however, this time when I tried to deploy my program (by clicking on the .msi file in the release folder) nothing was written out to the target folder, although the wizard said it was successful. The .msi file was 83kb.

Along with the .msi file and the setup.exe and setup.ini files, 2 new files that I haven’t seen before were written to the deployment project: InstMsiA.Exe and InstMsiW.Exe

Can anyone advise me?

Thank you.
