Neki pogođeni korisnici izvijestili su da opcija Pokreni^(Run) kao administrator nedostaje u kontekstualnom izborniku desnog klika za instalacijski program; ako je to slučaj, otvorite naredbeni redak u povišenom načinu rada^{(open the command prompt in elevated mode)} i pokrenite naredbu u nastavku. Zamijenite rezervirano mjesto UserName svojim stvarnim imenom korisnika/profila – i ako instalacijski program nije u mapi Preuzimanja^(Downloads) , umjesto toga navedite mapu.

Ovo rješenje zahtijeva da  izvršite čisto podizanje^{(perform a Clean Boot)} sustava Windows 10/11 uređaja, a zatim ponovno pokrenete instalacijski program. Ako se problem nastavi, isprobajte sljedeće rješenje.

6] Provjerite uslugu Windows Installer

Ovi softveri ovise o usluzi Windows Installer^{(Windows Installer Service)} . Dakle, ako imate problema s instaliranjem bilo kojeg softvera, vjerojatno je da MSI usluga nije omogućena. U tom slučaju provjerite je li omogućena usluga Windows Installer^{(Windows Installer Service is enabled)} .

Some affected users reported that the Run as Administrator option was missing from the right-click context menu for the installer; if this is the case, open the command prompt in elevated mode and run the command below. Replace the UserName placeholder with your actual user/profile name – and if the installer is not in the Downloads folder, specify the folder instead.

msiexec /i C:\Users\UserName\Downloads\EpicInstaller-7.7.0-fortnite-8fe19e2378554c299400a9974c30e172.msi

This solution requires you to perform a Clean Boot of your Windows 10/11 device and then run the installer again. If the issue persists, try the next solution.

6] Check Windows Installer Service

These software are dependent on the Windows Installer Service. So, if you’re having an issue installing any software, it’s likely that the MSI service is not enabled. In this case, ensure that the Windows Installer Service is enabled.

7] Unregister and re-register Windows Installer Service

To unregister and re-register Windows Installer Service on your Windows 10 or Windows 11 computer, do the following:

• Open Command Prompt in admin mode.
• In the command prompt window, type the command below and hit Enter to temporarily unregister the Windows Installer service:

msiexec /unreg

• Once the command is processed successfully and you get the success message, input the following command and hit Enter to register the Windows Installer once again:

msiexec /regserver

After the second command is processed successfully, restart your PC once again, and run the Epic Games Launcher installer again.

8] Assign Full Control to Windows Installer folder and Temp folder

Insufficient permissions on the Windows Installer folder and/or Windows Temp folder can give rise to the issue at hand.

In this case, you can assign Full Control permission to both folders. It is best to reverse the Permission changes you made after your job is done.

Hope something helps!
