Downloading copyrighted Microsoft installation files from non-Microsoft sources violates the software license agreement. Even if you own a valid product key, distribution rights are restricted.
If you have a valid product key from an old purchase, you can download the original ISO from Microsoft’s official backup service (if still available via your account). Otherwise, no reputable source exists. Avoid BitTorrent — those ISOs often contain modified files with malware.
Cybercriminals know that users searching for rare system files are often less cautious. They package keyloggers, ransomware, or remote access Trojans (RATs) inside a file named “OfficeLR.cab”. Once you extract or point the installer to it, the malware runs with elevated privileges.

Which scenario should I assume: (A) original CD/DVD, (B) downloaded installer EXE, or (C) repairing an existing Office 2007 install?
