Since it's an older version, Corel might not promote it anymore, but they might still have it available through their archives. I should check if Corel offers X7 for download. If not, suggesting they consider newer versions could be helpful. Newer versions might have better support, security, and features.
While searching for CorelDRAW X7 Portable 64-bit , it is important to note that Corel does not offer an official "portable" version of this software. Official versions typically require a full installation and an active license for legal and secure use. Risks of Unofficial Portable Versions
First, I should mention that downloading software from unauthorized sources is illegal. Need to stress the legal aspects and risks involved. Maybe they don't know where else to get a legitimate copy. So, directing them to the official Corel website would be a good start.
