Resolving Issues With 64-bit Error Messages

April 04, 2024

Already Having 64-bit Software Installed

Encountering an error message stating that 64-bit software is already installed when attempting to install a Microsoft Office product is a common issue, often stemming from a previously installed trial version of Microsoft 365. Here's a guide to resolving this error and ensuring a smooth installation process.

Identifying the Source of the Error

Before proceeding with troubleshooting, it's essential to understand why you're encountering this error message. In most cases, it occurs when there's a conflict with a previously installed trial version of Microsoft 365, which includes 64-bit components.

There are typically two options when presented with this error:

1. Installing 64-bit Option

If the provided error presents an option to "Install 64-bit", selecting this option will install the 64-bit version of the product to match the existing format of the software on the computer.

2. No 64-bit Option

If the provided error does not present an option to install and only to close. This typically can happen when there is a conflicting version of the Office suite. This means that another software needs to be uninstalled before the installation can be completed. A common example involves Microsoft Office 365. This would lead to the following choices:

3. Installing Another Version

If installing another version of Microsoft Office it is recommended to uninstall the office 365 first to prevent any conflicts and being prompted with signing up for a subscription. 

  • Note: If still receiving errors after uninstalling Office 365 from Settings, May need to use Microsoft Office Scrubber Tool. See the following section on how to complete that: Microsoft Office Scrubber Tool

If installing Project / Visio and are only using Microsoft 365, then see the steps on how to install here: Visio/Project Standard/Professional Install Alongside 365
