I want to reinstall this software and use it on my PC because when I want to open this program an error occurs & reports that I should reinstall the software. It is missing out some files. Please help me! How can I reinstall and use it for free?
Download the package again and launch it from your desktop or from the location you saved it to. The installation will replace all the missing/corrupted files and repair the associations.
The winrar is not completely available for free but you can use most of it's features for free.
