I think you will have to state your question more clearly. What was the application that you were installing? Did you unzip it directly into the \
$UserBaseDirectory/Applications folder or \$BaseDirectory/Applications folder? You may have it at the wrong level or have created an extra level of folders. Unzipping will generally create a folder with the application name so you don't want to create an extra one. The file structure should look like:
\$UserBaseDirectory/Applications/applicationName/
packageName.m...
