[FIX] Microsoft Office 365 Error Code 0-1012

Installing Microsoft Office is, in most cases, really an easy task to do. All you have to do is download the installer and just through the prompts. That and you have a fresh installation of the MS Office on your system available. However, there are some cases when the installer does not go as intended and instead throws out an error message that stops it from installing. This can be very annoying but if you know just the right ways of fixing it, it isn’t really tedious. One of the error messages or error codes that users encounter while installing MS Office is the Error Code 0-1012.

Office 365 Error 0-1012

As it turns out, the error message indicates that the issue can be caused by two reasons. First of all, if you are not connected to the internet and you are using the online installer of MS Office, you might face the error. Secondly, if you do not have enough space on your hard disk for MS Office, the said error might be triggered. While these are true and the causes can be held accountable, fixing these two problems doesn’t really get rid of the error message in some scenarios.

This is because in some cases the issue is not really caused by the indicated causes in the error message. Rather, there are scenarios when the error message pops up due to other reasons that we are going to mention down below so you establish a better grasp of the issue. Let us get started.

  • User Account — This is something that has been confirmed by several users. The error message might appear due to your user account in some cases. This often happens when you have multiple user accounts on your PC and one of them doesn’t have the privileges. Therefore, in order to get rid of it, you will have to use a different user account to install the software.
  • Old Installation Files — As it turns out, in some cases if you are trying to reinstall the MS Office on your system, the leftover files might prevent the installation from completing properly. If this case is applicable to you, what you got to do is use official tools from Microsoft to get rid of any remaining files and then continue with the Office installation.

Now that we have gone through the potential causes of the said error, let us go through the methods that you can follow to fix the Error code 0-1012. Before you proceed with the methods given down below, please make sure that you have enough space on your hard disk to actually install Office as suggested in the error message. Therefore, make sure that you have at least around 30 gigs of free space available. In case you do and still get the error message, you can try using the offline installer to see if that works out. If that does not work out either, follow through the methods down below.

Method 1: Change User Account

One of the ways that you can actually solve the error is to switch user accounts. If you have multiple user accounts on your system, this error can often occur. Thus, in order to resolve it, you will have to change your user account. As it turns out, in some scenarios, the issue occurs when the user account that you are using to install Office does not have administrative privileges. This can happen when you are remotely connected to the system via a user account that has remote access to the PC.

So, all you have to do is to ensure that you are using an administrator account while installing Office. Now, there are different ways that you can check if the account you are using is an administrator account or not. Follow the instructions down below to check for yourself.

  1. First of all, open up the Start Menu by pressing the Windows key.
  2. Now, there are two ways you can the account you are on.
  3. You can either hover your mouse of the small profile listed on the left-hand side of the Start Menu. Right-click the icon and then select Change Account Settings from the menu that appears.
    Accessing User Account
  4. Alternatively, you can just simply search for User Accounts in the Start Menu and then choose the result under Best Match.
  5. If you do it via the user account icon on the left, you will be taken to the Your Info tab. Here, if your account is an administrator account, you will be able to see Administrator written under your account name.
    User Account Details
  6. In case you searched for the user accounts, you will have to switch to the Your Info tab to check your account.
  7. To find an administrative from the user accounts, go to the Family & other users tab.
    Other User Accounts
  8. Here, just click on one of the user accounts and you will be shown the details.
  9. Once you find the administrator account, restart your system and login to that account.
  10. Finally, try installing MS Office again to see if the issue persists. You can try downloading the installer again if the error still occurs.

Method 2: Remove Leftover Office Files 

If you are trying to reinstall MS Office and getting the error message, it could very well be due to the leftover files of the previous Office installation. When you uninstall MS Office, not all of the files are deleted. Rather, some configuration files are leftover along with registry keys which can sometimes interrupt the installer when you are trying to do a fresh install. Therefore, what you have to do is remove all the previous files and then try installing Office. Follow the instructions down below to do so:

  1. First of all, download the uninstall tool from here.
  2. Once you have downloaded the tool, run the executable file, and select the version that you wish to uninstall.
    Office Uninstaller
  3. Then, follow through the remaining screens of the uninstaller.
  4. Once you have done that, you will have to delete a registry key. Open up Powershell by searching for it in the Start Menu and then copy paste the following command:
    reg delete HKLM\SOFTWARE\Microsoft\ClickToRun\OverRide /v LogLevel /f
    reg delete HKLM\SOFTWARE\Microsoft\ClickToRun\OverRide
  5. Paste the first command and see if that works out. In case you are shown an error message, then paste the second command instead.
  6. After that, try using the installer to see if that fixes the issue.
  7. You might have to use the uninstaller more than once in case the error persists.
