Once you download a complete ISO, use HashMyFiles or CertUtil to confirm the SHA-1 matches a known good release. Example for Office 2007 Pro Plus (English):

If your ISO’s hash matches a known community-verified hash, you can extract OfficeLR.cab from it.
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. The original Office 2007 disc may be scratched or dirty
Microsoft once offered a “Fix It” tool for Office installation errors. While no longer supported, the MicrosoftOffice2007SetupDiagnostic might still help. Search the Microsoft Catalog for KB articles like 924611 – these sometimes remap source paths.
If only OfficeLR.cab is missing, you might extract it from a complete Office 2007 source. However, Microsoft no longer provides this file for download. Do not download .CAB files from third-party websites — they are a common malware trap. SHA-1: d67b8f6f3b82f4f4e21463fc52ae2e8e8c5c3735
Instead of hunting for a risky standalone download, try these proven methods.
