On another thread that has been marked as solved, the suggestion was given, "Create a folder on your desktop called "Office.en-us". Find the same folder on the CD and copy "OfficeMUISet" to the folder on your desktop.
Re-insert the CD so that the setup starts again.
When it tells you it cannot find the file and wants you to select a folder, click on DESKTOP.

It takes a minute to get started but it will install just fine. "

I tried that and it says, "Cannot copy OfficeMUISet: Access is denied. Make sure the disk is not full or write-protected and that the file is not currently in use."

Any other solutions?

Two routes appear in this thread: leftover Office state and interference from endpoint/security software. eventually traced the failure to a security product; correctly pointed out that remnants of prior Office installs can also complicate setup. The steps below focus on diagnosing which situation is present and resolving it safely and reproducibly.

A verbose Windows Installer log shows the failing action. When the MSI is reachable on the install media, run it from an elevated prompt and capture a log, for example:

msiexec /i "C:\full\path\to\OfficeMUI.msi" /L*V C:\Temp\OfficeInstall.log

Search the log for strings like ACCESS DENIED or return value 3. Use Process Monitor (Sysinternals) with a filter for the MSI name or path to see the exact process returning ACCESS DENIED — that pinpoints whether an AV/endpoint, a system service, or a permissions issue is blocking the file operation.

If an endpoint product is blocking the installer, allow a temporary exclusion for the installer path or briefly pause protection (do not leave protection disabled). If permissions are implicated, confirm write access on %TEMP% and the Windows Installer cache and run setup elevated. If media read errors appear, mount or copy the full installation source to a local folder and run from there. For stubborn installer/registry corruption, use Microsoft's Program Install and Uninstall troubleshooter before retrying. After a successful install, reenable protection and apply updates as available.

Well never got any msg of this sort, but first, try remove any present Office installation from your Program Files folder, and if need be, clean your pc using CCleaner to remove any registry which may still be in use.
Setting up afterwards from the CD itself, no need to create a folder and copy setup files...
Also make sure u are using the correct setup file, as Windows comes with 32/64 bit...

It turns out that all I had to do was go into Administrative Tools --> Services --> And stop all Sophos services.
