Hello Yimcooldude,
Can you confirm the OS in which you are trying to install these applications on and confirm whether or not you are currently behind a proxy or corporate network?
You can also try deleting the application folders from the install directory as the applications themselves may not have been downloaded correctly. If on Mac you can find those applications in the user-level applications folder inside the AirspaceApps subfolder.
/MacintoshHD/Users/%username%/Applications/AirspaceApps/ (move to trash)
If on Windows please navigate to the following directory and delete the application folders you are having issues with.
%appdata%/Local/AirspaceApps/ (delete corresponding applications folders that will not install)
After you have done the above please proceed to restart your Airspace Home and try clicking an application to install it. Please let me know if this helped to resolve your issue.
