We had several computers deployed with the 64 bit version of Office 2013. Due to some unforeseen compatibility issues, we needed to remove the 64 bit version and then install the 32 bit version.  While we have been able to remove the 64 bit version, we are not able to install the 32 bit version. After we click setup.exe,  We simply see the Office 2013 splash page that mentions "Please wait while setup prepares the necessary files" and then it disappears. Nothing in the event log either. Any idea what is going on and how to resolve this?

Hi,

Do you mind telling us which category of Event viewer have you checked?

Most of the setup error log may be stored in Setup category, and some in Application category.

If there are some error logs, please upload, they'll help us to troubleshoot this issue.

Then, this issue also may be due to the remain of Office 2013 64bit. I recommend we remove it manually and clean the registry key:

==========

Method 1

• Open C:\Program Files\Microsoft Office 15\root\integration\ 
• Delete all C2RManifest*.xml files in that folder.
• Open an elevated command prompt. Tap on Windows, enter cmd, right-click on the result and select run as administrator from the menu.
• Type cd "C:\Program files\Microsoft Office 15\root\integration".
