Solution 1 – Check Your Antivirus for Another Installation is in Progress Office 365:

In some cases, another installation error may appear due to your antivirus. Third-party antivirus can often interfere with your system and cause this and other problems.

To solve the problem, it is recommended to temporarily disable certain antivirus functions or your antivirus completely. If that doesn’t work, your next step would be to completely remove the third-party antivirus from your PC.

Windows 10 comes with Windows Defender that works as a default antivirus, so even if you remove a third-party antivirus, it must remain protected. If removing the antivirus resolves the problem, you should consider switching to a new antivirus solution. If you want maximum protection that does not interfere with your system, you should definitely try BullGuard.

Solution 2: Look for Another Installation Process:

Sometimes, you may have another installation running in the background, and that could generate another installation message in progress while you install Office 365. To fix this problem, you must stop the installation on your own or use the Task Manager to finish the installation process.

To do that, just follow these steps:

1. Press Ctrl + Shift + Esc to start Task Manager.
2. When Task Manager opens, look for the installation that runs in the background. Office installation processes are usually IntergratedOffice.exe and Microsoft Click-to-Run.
3. Right-click on the installation process and choose End Task from the menu.

It is also worth mentioning that the Windows Installer and msiexec processes can cause this problem to appear, so if you see them running, be sure to disable them. After closing the problematic process, try installing Office again.

Solution 3 – Correct the error 0-1018 0 with the System File Checker

In some cases, your installation may get corrupted, and that may cause another installation to appear in progress. If you encounter this problem when trying to install Office 365, you may be able to solve the problem by performing an SFC scan.

To do that, follow these steps:

1. Press the Windows + X key to open the Win + X menu. Alternatively, you can right-click the Start menu button. Choose Command Prompt (Admin) or PowerShell (Admin).
2. After the command prompt starts, enter sfc / scannow and press Enter to execute it.
3. The SFC should now start. It is worth mentioning that the scan can take around 15 minutes, so do not interfere with it.

Once the SFC scan is complete, check if the problem is resolved. Several users reported that the problem may persist even after running an SFC analysis. If that is the case, you must run the DISM scan by doing the following:

1. Start the command prompt as administrator.
2. Enter the DISM / Online / Cleanup-Image / RestoreHealth command and press Enter to execute it.
3. Note that the DISM scan may take about 20 minutes, so do not interfere with it.

Once the DISM scan is finished, check if the problem is still there. If the problem persists, or if you could not perform an SFC scan before, be sure to run the SFC scan again.

Solution 4: Register Office 365 DLL Dependencies:

Office 365 may be missing some DLLs (dynamic link library files) needed to start. You can fix it by registering the DLL dependencies as follows.

1. Press the Win key + hotkey R to open Run.
2. Then enter “regsvr32 office start.dll” in the Run text box as shown below.
3. You can now press the OK or Enter button to register the DLL dependencies.

Solution 5 – Uninstall Other Versions of Office:

Sometimes, earlier versions of Office may interfere with your current installation and cause another ongoing installation error to appear. If that is the case, you must search and remove all Office installations from your PC.

You can do it using the regular method, but this method can sometimes leave behind certain files and registry entries. These leftover files may interfere with future Office installations, therefore it is always recommended to use uninstall software to remove applications from your PC.

If you are not familiar with it, the uninstall software is a special application that can remove any application from your PC, but it will also delete all the files and registry entries associated with that application.

If you are looking for an easy-to-use uninstall software, we recommend you try Revo Uninstaller. Once you delete all previous versions of Office from your PC, the problem should be completely resolved.

Solution 6 – Run the Office 365 FIXIT tool

1. There is also an Office 365 FIXIT tool that will completely remove the MS Office installation files. You can open that by pressing the Download button on this page.

6. When the troubleshooter is finished, press Next and Close.
7. Press the Start menu button and restart Windows.

Solution 7 – Disable Windows Firewall

Sometimes another installation error may appear due to the Windows Firewall. Office 365 installations need to download certain files from the Internet, and if your firewall is blocking it, you may encounter certain error messages.

To solve this problem, it is recommended that you temporarily disable your firewall. To do that, just follow these simple steps:

1. Press the Windows key + S and enter the firewall. Select Windows Defender Firewall from the list.
2. The Windows Defender Firewall window will now open. Select Enable or disable Windows Defender Firewall from the menu on the left.
3. Now select Disable Windows Defender Firewall (not recommended) for private and public networks. Once you are

In fact, click on the Accept button to save the changes.

After disabling the Windows Firewall, try installing Office 365 again and check if the problem reappears. Once you manage to install Office 365, reactivate your firewall.

Solution 8 – Install the latest updates

Sometimes, this error message may appear due to certain failures in your system. However, Microsoft is working hard to solve these problems, and the best way to solve them is to install the latest updates.

For the most part, Windows 10 installs the missing updates automatically, but sometimes you can skip one or two updates. However, you can always check for updates manually by doing the following:

1. Open the Configuration application. You can do it instantly using Windows Key + I shortcut.
2. When the Settings application opens, you must navigate to the Update and security section.
3. Click the Check for updates button.

Windows will now look for available updates. If updates are available, they will be automatically downloaded in the background and installed as soon as you restart your PC. Once your system is up to date, check if the problem is still there.

You should now be able to install Office 365 on Windows 10 with those fixes. The Microsoft Support and Recovery Assistant tool for Office 365 and Outlook, for which this publication of the Windows Report provides more details, could also be useful for correcting error 0-1018 0 and other things.

And I am sure that any disaster that would have happened for a few is due to system hardware dependencies. An old computer that was upgraded from XP to 10 is certainly not compatible with these programs. It is a coincidence to have problems like 1 in 100.
