PrimeTool 7.0.5 software, delivered as a 147 MB RAR archive. The name offers no further description, so the exact purpose of this utility should be confirmed after extraction, preferably by reading any included documentation. Large repair-tool packages of this kind generally bundle drivers and support files along with the main program. Scan the archive with antivirus software, run it on a dedicated workstation, and check compatibility with your operating system before connecting any programmer or device under repair.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @esquemaseletricos. Enginerys does not host this file.
