Giveaway of the day is a website which offers a software everyday for free, and you will have to download, install and activate the software before the 24 hours time of the giveaway.. If you are hearing it for the first time here is the link.
The setup file is having a wrapper around it , which will check the time limit and run the installer.
UnWrapper GOTD is a tool from Raymond which will help you to extract the installer file for you and save it on your desktop for future use. The procedure is simple
Run the UnWrapper GOTD
locate the setup.exe file
complete the installation
Few more points
If it is not working for you, just give the administrative (“Run as Administrator”) and check.
Note: Like the other tools that worked previously, this will only work on software that is still within the 24 hour giveaway period because the Giveaway of the Day server still needs to be contacted, and will say anything run outside this time frame has expired. This UnWrapper GOTD tool is still in development where future version promises to include the ability in extracting setup file without connecting to the GAOTD activation server.
