It's likely this one is corrupted. Attempt to launch & "[File path to nmap.exe]" --version command from Powershell If this works, attempt manual installation outlined in above Docs again. There may be permissions errors or pieces missing from command execution path. If step 4 returns null, attempt to run Nmap.exe If nmap.exe launches, try manual installation again and check permissions/file path/etc The most common cause is an "MSCVR120.dll is missing" error when attempting to launch nmap.exe. This can be caused by Antivirus blocking the installation of the package. Alternatively the wrong version of the package may be installed (x64 instead of x84 for older servers). Applicable Versions Kingston and higher Additional Information May also be caused by PRB1292511, which is caused by an existing installation of npcap on the system.
