Error installation

Click to expand...

1. Press Win + S, type cmd, right-click Command Prompt → Run as administrator
2. Type the following (adjust the path to match your download location):

msiexec /i "C:\Users\VOTRE_NOM\Téléchargements\Multiecuscan 5.3 R1 MultiLanguage\Multiecuscan 5.3 R1 MultiLanguage\SetupMultiecuscan53R1.msi"

• Make sure Windows Installer service is running: Win + R → services.msc → find Windows Installer → right-click → Start (or Restart)
• Temporarily disable your antivirus — some AV tools block MSI temp file creation
• Copy the entire extracted folder to C:\Temp\ and run the MSI from there (avoids permission issues with deep/nested download paths)

• Exclusion cartella/file (better than disabling everything):
  Copia/estra the files into a folder such as C:\Temp\Multiecuscan and then add an exclusion in Windows Security (Antivirus & threat protection) for:
  1) C:\Temp\Multiecuscan
  2) possibly also SetupMultiecuscan53R1.msi
• Run as Admin: always install by right-clicking → Run as administrator
• Disable “Real-time protection” only during installation:
  Windows Security → Virus & threat protection → Manage settings → disable “Real-time protection”.
  Re-enable it immediately after installation.
• Also check “Controlled folder access”:
  Windows Security → Ransomware protection → Controlled folder access
  → disable it temporarily, or allow msiexec.exe / the installation folder.
• Use a “clean” installation from the local folder:
  Do not launch the MSI from Download</b] or from strange zip/percorsi: extract everything to C:\Temp\... and run it from there.
  [*]Reinstalla/installa Windows Installer component (if it continues): repairing Windows Installer from the system is rare, but if the error persists together with AV, it is almost always the antivirus blocking it.
