This thread is about installing the Smart‐Thinker_‐_UserProfile__Trial_PA_04.03.14 version on the new DNN 5.0 RC2 release. The intention of this thread is purely informational. These are some of my findings about a new installation on DNN 5.0 RC2
First you need to log in as host. Go to Module definitions under the host tab. Now you will see that the page is a bit changed from the previous 4.9 version. Click on the Install Module link at the very bottom of the page. The next screen will show up. Where you now have to select the module through clicking the browse button.

After selecting your module click the next button. You will see a message in red that the package contains files with invalid file extensions. This because of adjustments to the DNN core.

Check the Ignore File Restrictions and another message will show up.

Now select your module again through clicking the browse button and click next.

After doing this you will now see the Packing Information.

Click next and the Release Notes will show up.

Click next and the Review License appears.

When we finally click on next the module will be installed. What a procedure to install a module. I can only encourage these changes for the modules page. Because I think that there are now many more possibilities to work with modules.
