Questo articolo contiene alcuni degli errori più comuni che puoi riscontrare durante l'installazione di AdGuard per Windows e i possibili modi per risolverli.

Errore 5: Accesso Negato​

Questo messaggio d'errore appare quando le autorizzazioni necessarie non sono state garantite. Potrebbero esistere diversi motivi per cui il programma d'installazione di AdGuard non ha le autorizzazioni richieste per terminare correttamente il processo d'installazione. Puoi provare i seguenti passaggi:

  • Disabilita temporaneamente il antivirus. Alcuni di essi potrebbero interferire con l'installazione, a seconda della gravità delle loro impostazioni.

  • Scegli una cartella d'installazione differente. È possibile che la cartella d'installazione corrente preveda delle limitazioni d'accesso. Assicurati, inoltre, di non selezionare un'unità esterna, un'unità virtuale, etc.

  • Riavvia il tuo computer. Talvolta i problemi di autorizzazione sono temporanei e risolvibili riavviando il PC.

Errore 112: Il disco è pieno, Errore 1632: Cartella temporanea piena o inaccessibile​

Esistono due errori differenti con soluzioni molto simili. As their titles suggest, AdGuard installer didn't find enough disk space to complete the installation. Esistono diverse cose che puoi tentare per risolvere questo problema:

  • Disinstalla alcuni programmi o elimina i file non necessari, dall'unità in cui stavi tentando d'installare AdGuard.

  • Scarica, installa ed esegui AdwCleaner, un software gratuito di Malwarebytes. It will, among other things, clean your system from all kinds of extra "leftover" files that remain after incorrectly uninstalled programs and such. It will help clean up some disk space.

  • Riavvia il tuo computer. Sometimes temporary files can take up a considerable amount of disk space, and restarting your PC is the most reliable way to get rid of them.

Error 1601: Windows Installer is not accessible​

You could say this is a particular subcategory of Error 1603. The possible solutions are similar:

  • Start and re-register Microsoft Installer service. It requires some work.

    1) Press Win + R and enter services.msc. 2) Find in the list and double click Windows Installer. 3) Hit Start button under Service status and hit OK. If the service status is running, you should click Stop first and then hit Start. 4) Press Win + R, type and enter msiexec /unregister and hit Enter. 5) Press Win + R again, type and enter msiexec /regserver and hit Enter

  • Reboot the PC and start the installation all over again. Sometimes that's enough to fix the problem.

Error 1602: Canceled by user​

If you got this error code, chances are you have interrupted the installation process manually in one way or another. What you can do is:

  • Don't close the installer window. When the installation is complete, it will close automatically.

  • If a dialogue window pops up during the installation, hit "Yes" to grant the installer the required permissions. Clicking "No" will cancel the installation.

  • Don't start other processes while the installation process is going on.

Error 1603: Fatal error during installation​

The error sounds scarier than it actually is. In reality, this is a rather generic error that can have many different causes, and some of them are easily fixed. Try the following solutions:

  • Press the Win key, search for Command Prompt and run it. There, type in sfc /scannow and press Enter.

  • Scegli una cartella d'installazione differente. È possibile che la cartella d'installazione corrente preveda delle limitazioni d'accesso. Assicurati, inoltre, di non selezionare un'unità esterna, un'unità virtuale, etc.

  • Uninstall AdGuard using our special uninstall tool and then repeat the installation.

  • Start and re-register Microsoft Installer service. It requires some work.

    1) Press Win + R and enter services.msc. 2) Find in the list and double click Windows Installer. 3) Hit Start button under Service status and hit OK. If the service status is running, you should click Stop first and then hit Start. 4) Press Win + R, type and enter msiexec /unregister and hit Enter. 5) Press Win + R again, type and enter msiexec /regserver and hit Enter

  • Acquire full permissions on the drive for installation. It is possible that the error 1603 occurs because you don’t have full permissions on the file location. It's also not as easy as some of the other solutions:

    1) Open File Explorer, right-click the drive containing the installation location and select Properties. 2) Go to Security tab and click Edit. 3) Single-click SYSTEM and ensure that the Allow box of every item in Permissions for SYSTEM is checked (if it is checkable). Do the same check for Administrators. 4) Click OK to go back to Properties dialog. Then click Advanced. 5) Click Change Permissions. 6) On Permissions tab, double-click Administrators. 7) Select This folder, subfolders and files for Applies to field and check all the available Basic permissions. After that, hit OK. 8) Do the same operation above (from item 7) for SYSTEM. 9) Click OK all the way out. Try installing AdGuard again.

Error 1618: Another installation is already in progress​

This error occurs when there are several instances of AdGuard installer launched at the same time. What to do if you get this error:

  • Reboot your PC and start the installer again. When you restart the computer, all ongoing processes will stop, including all copies of the installer.

  • Don't make multiple clicks on the installer even if it doesn't start right away. Sometimes it may take a few seconds to display the installer UI.

Error 1638: Another version of this product is already installed​

It's very likely that you've already installed AdGuard before.

  • Check if AdGuard is already installed on your computer. You can do it by pressing the Win key and typing in AdGuard.

  • Maybe there're some leftover files from a previous AdGuard installation. Uninstall AdGuard using our special uninstall tool and then repeat the installation.
