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)

• Esclusione cartella/file (meglio che disattivare tutto):
  Copia/estra i file in una cartella tipo C:\Temp\Multiecuscan e poi aggiungi un’esclusione in Windows Security (Antivirus & protezione minacce) per:
  1) C:\Temp\Multiecuscan
  2) eventualmente anche SetupMultiecuscan53R1.msi
• Run as Admin: installa sempre con tasto destro → Esegui come amministratore
• Disattiva “Protezione in tempo reale” solo durante l’installazione:
  Windows Security → Protezione da virus e minacce → Gestisci impostazioni → disattiva “Protezione in tempo reale”.
  Dopo l’installazione riattivala subito.
• Controlla anche “Controlled folder access”:
  Windows Security → Protezione da ransomware → Accesso cartelle controllato
  → disattivala temporaneamente, oppure consenti msiexec.exe / la cartella di installazione.
• Usa un’installazione “pulita” dalla cartella locale:
  Non avviare l’MSI da Download</b] o da zip/percorsi strani: estrai tutto in C:\Temp\... e lancia lì.
  [*]Reinstalla/installa Windows Installer component (se continua): fai un repair di Windows Installer dal sistema è raro, ma se l’errore persiste insieme ad AV è quasi sempre l’antivirus a bloccare.
