Some of the other related error codes are, 30088-1015, 30183-1011, and 0-1005. You may encounter the error if there’s an issue with the network connection or if the hard drive is short of space. Fortunately, there are a few possible solutions for the Microsoft Office 365 error code 0-1011.

Follow the below instructions to use the offline installer to install Office:

Method 5: Temporarily turn off proxy settings
Sometimes using a proxy server can create issues with the network connection and thus, you may face an issue installing the Office app and see the error code 0-1011. You must disable it to check if it helps fix the issue. Here’s how:
Step 1: Press the Win + X shortcut keys on your keyboard and select Run.
Step 2: In the Run command window that opens, type inetcpl.cpl in the search field and press OK to open the Internet Properties window.

Now, try installing the Microsoft Office 365 and you should not see the error anymore.
Method 6: Temporarily Turn Off Anti-virus
Sometimes, you may encounter the error code 0-1011 while installing the Microsoft Office 365 due to the 3rd party antivirus on your system that may be blocking the program considering it as a threat. You can turn off the antivirus software temporarily or even install it, to check if this helps fix the issue.
Alternatively, you can also turn off the built-in antivirus software on your Windows 10 PC. To turn it off temporarily, follow the below steps:
Step 1: Press the Win + I keys together on your keyboard to launch the Settings app.
Step 2: In the Settings app, click on Update & Security.
Step 3: In the next window, click on Windows Security option on the left side of the pane.

Step 5: It will open in new Windows Security pane.
Here, on the extreme right side, under the Who’s protecting me? section, click on Manage providers.
Step 6: Next, on the right side, under the Antivirus section, select Microsoft Defender Antivirus and switch it off.
Once, the Windows Defender Antivirus is turned off, exit Settings window and try installing the Microsoft Office 365 and it should finish installing without any errors now.
Method 7: Temporarily Turn Off Firewall
Step 1: Right-click on Start and select Run to open Run command.
Step 2: In the search box, type firewall.cpl and hit Enter to open the System and Security window in the Control Panel.
Step 5: In the next window, select Turn Windows Defender Firewall on or off.
Step 6: In the Customize Settings window, under the Customize settings for each type of network, select the radio buttons next to Turn off Windows Defender Firewall for both Private and Public network settings.
Press OK to save the changes and exit.
Now, exit Control Panel and check if you can reinstall the Microsoft Office 365 program.
If none of the above method works, you can try using a wired internet connection, or try connecting to internet in a different location. Alternatively, you can try to install the program from home instead of your office or school because the network might not be working properly in these locations.
