Windows Installer je osnovna usluga koja upravlja instalacijama svega u sustavu Windows^(Windows) , uključujući aplikacije, značajke i mnoge druge stvari. Ako se iz nekog razloga pokvari, zaglavit ćete s novim instalacijama, pa čak i nadogradnjama aplikacija.

Windows Installer (msiserver) ne radi

U ovom ćemo postu podijeliti popis kodova pogrešaka – i njihovo rješenje, od kojih neki upućuju na naše postojeće rješenje – i kako ih riješiti.

1] Pokrenite alat za rješavanje problema instaliranja^{(Run Program Install)} i deinstaliranja programa^{(Uninstall Troubleshooter)}

Prva stvar koju bismo predložili je pokretanje  alata za rješavanje problema instaliranja i deinstalacije programa kako biste popravili probleme koji blokiraju instalaciju ili uklanjanje programa zbog oštećenih ključeva registra. Ovaj program će popraviti oštećene ključeve registra na 64-bitnim operativnim sustavima, koji kontroliraju podatke o ažuriranju, probleme koji sprječavaju potpuno deinstaliranje ili ažuriranje postojećih programa i probleme koji blokiraju deinstaliranje programa putem Add or Remove Programs (ili Programi^(Programs) i Značajke^(Features) ) na upravljačkoj ploči^{(Control Panel)}

2] Pokrenite^(Start) uslugu Windows Installer^{(Windows Installer Service)}

U prompt Pokreni upišite  MSIExec , a zatim pritisnite Enter.

Ako dobijete prozor Windows Installer koji vam govori sve o MSIExec- u, onda je sve u redu.

Ako dobijete pogrešku, možda ćete je morati pokrenuti ručno.

Desnom tipkom miša kliknite^{(Right-click)} programsku traku i odaberite Upravitelj zadataka^{(Task Manager)} . Prijeđite^(Switch) na Usluge^(Services) i potražite msserver^(msiserver) . Započni.

Također možete pokrenuti services.msc da otvorite Windows usluge^{(Windows Services)} i idite na Windows Installer i ponovno ga pokrenite.

3] Ne može se pristupiti usluzi Windows Installer^{(Windows Installer Service)}

Možda ćete vidjeti poruku Windows Installer Service se ne može pristupiti^{(Windows Installer Service could not be accessed)(Windows Installer Service could not be accessed)} . To se obično događa ako je Windows Installer Engine oštećen, nepravilno instaliran ili onemogućen. Morat ćete popraviti ili oštećenje ili popraviti konfiguraciju ili je omogućiti. Povezani post također rješava problem gdje se usluga Windows Installer nije mogla pokrenuti i daje poruku kao Pogreška 5, pristup je odbijen.^{(Error 5, Access is denied.)}

4] Postoji problem s ovim paketom Windows Installer

Ako se paket Windows Installer suoči s nestabilnim pristupom mreži tijekom procesa deinstalacije ili instalacije, ponekad se pogreška može pojaviti ako ne dovršite postupak uspješno. Poruka o pogrešci može izgledati kao " Postoji problem s ovim Windows Installer paketom^{(There is a problem with this Windows Installer package)} . Nije moguće pokrenuti program potreban za dovršetak ove instalacije. Obratite se osoblju za podršku ili dobavljaču paketa.” ^{(“There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor.” )}

5] Windows Installer se stalno pojavljuje

Obično  Windows Installer  ili  msiexec.exe radi u pozadini. Možete provjeriti u Upravitelju zadataka^{(Task Manager)} ispod popisa procesa koji se izvode. Međutim, ako vidite da stalno radi, a Windows Installer se stalno pojavljuje^{(Windows Installer keeps popping up)} , to znači da je zapeo. Moguće je da instalacija nije u mogućnosti dovršiti, a to se događa kao rezultat.

6] Instalacijski paket^{(Installation Package)} nije se mogao otvoriti

Ako ne možete instalirati softver koji ste upravo preuzeli s interneta, a on stalno prikazuje poruku o pogrešci " Instalacijski paket nije se mogao otvoriti^{(Installation Package could not be opened)} ", onda je to vjerojatno sigurnosni problem. Windows često blokira aplikacije koje preuzimate s interneta jer im ne vjeruje. Možda ćete ga morati deblokirati ili onemogućiti antivirusni program da biste ga popravili.

7] Ponovno registrirajte uslugu Windows Installer

Ako ništa ne uspije, najbolja opcija prema našem iskustvu je ponovno registrirati uslugu Windows Installer . Razlog zašto radi sjajno jer popravlja i probleme s registrom i ponovno priprema osnovne postavke.

Pokrenite naredbeni redak s administratorskim privilegijama. Upišite sljedeće naredbe i pritisnite Enter nakon svake.

%windir%\system32\msiexec.exe /unregister

%windir%\system32\msiexec.exe /regserver

%windir%\syswow64\msiexec.exe /unregister

%windir%\syswow64\msiexec.exe /regserver

Zatvorite naredbeni redak, spremite sav svoj rad i ponovno pokrenite računalo.

Provjerite imate li problema s Windows Installerom^{(Windows Installer)} .

Windows OS održava predmemoriju programa Windows Installer . Sve datoteke koje instalirate privremeno se ekstrahiraju ovdje i zatim instaliraju na računalo. Ako ovdje brišete datoteke ručno ili tijekom instalacije ili bilo koji drugi program to radi, dobit ćete pogrešku.

Windows Installer not working properly in Windows 11/10

Windows Installer is a core service that manages installations of everything in Windows including apps, features, and many other things. If for some reason, it breaks, you will be stuck with new installations and even upgrades of apps.

Windows Installer (msiserver) not working

In this post, we will share a list of error codes – and their solution, some pointing to our existing solution – and how to solve them.

1] Run Program Install & Uninstall Troubleshooter

The first thing we would suggest is to run the Program Install and Uninstall Troubleshooter to repair issues that block program installation or removal because of corrupted registry keys. This program will fix corrupted registry keys on 64-bit operating systems, which control the update data, problems that prevent existing programs from being completely uninstalled or updated, and problems that block you from uninstalling a program through Add or Remove Programs (or Programs and Features) in Control Panel

2] Start the Windows Installer Service

In the Run prompt, type MSIExec, and then press Enter.

If you get the Windows Installer window which tells you everything about MSIExec, then it’s all good.

If you get an error, you might have to start it manually.

Right-click on the taskbar, and select Task Manager. Switch to Services, and look for msiserver. Start it.

You can also run services.msc to open Windows Services and go to Windows Installer, and restart it.

3] Windows Installer Service could not be accessed

You may see the message Windows Installer Service could not be accessed. This usually happens if the Windows Installer Engine is corrupted, installed incorrectly, or disabled. You will need to fix either the corruption or fix the configuration or enable it. The linked post also solves the issue where the Windows Installer service could not start, and gives the message as Error 5, Access is denied.

4] There is a problem with this Windows Installer package

If the Windows Installer package faces unstable network access during the uninstallation or installation process, sometimes, the error might appear if you fail to complete the process successfully. The error message might go like “There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor.” 

5] Windows Installer keeps popping up

Usually, the Windows Installer or msiexec.exe runs in the background. You can check in the Task Manager under the list of processes that are running. However, if you see it constantly running, and the Windows Installer keeps popping up, it means it is stuck. It is possible that an installation is not able to complete, and this happens as a result.

Read: Windows Installer Service missing.

6] Installation Package could not be opened

If you are not able to install a software which you just downloaded from the internet, and it keeps throwing error message “Installation Package could not be opened“, then it’s probably a security issue. Windows many a time blocks applications you download from the internet as it does not trust them. You may have to unblock it or disable your antivirus to fix it.

7] Re-register Windows Installer service

If nothing works, the best option in our experience is to re-register the Windows Installer service. The reason why it works great because it fixes registry issues as well, and gets the basic settings ready again.

Launch the command prompt with admin privileges. Type the following commands and hit Enter after each one.

%windir%\system32\msiexec.exe /unregister

%windir%\system32\msiexec.exe /regserver

%windir%\syswow64\msiexec.exe /unregister

%windir%\syswow64\msiexec.exe /regserver

Close the command prompt, save all your work, and restart your computer.

Check if you are facing Windows Installer issues.

Windows OS maintains a Windows Installer cache. Any files you install are temporarily extracted here and then installed on the PC. If you are deleting files from here manually or during installation or any other program is doing that, you will get an error.
