Error 0x800488fc

Hello, 

I have been trying to install using Office 365 (which has worked on previous circumstances but needed to re-install), on a macbook - (operating system 10.9.5), (Microsoft Office 2011).  Download was successful, however when using Microsoft Office Setup Assistant, I received the error 0x800488fc. I am using my student account from my university, when I purposely mis-typed my account address it recognised the error and so my account is active. I have tried to install the software 3 times but with no success and the same error. The language settings is in the United States English format, and the link used was through the office 365 email pathway. Now, I need your expert assistance. 

Thank you for your time,

Stephanie 

hi stephanie,

as your mac operating system is 10.9.5, could you go to the portal.office.com/.../mysoftware.aspx page and sign in with the office 365 account successfully to re-download the office 2011 for mac package? if office 2011 for mac has been downloaded and installed before, please remove it completely before re-downloading and re-installing.

Hi Stephanie,

Thanks for your updates.

The test account is just used to check the cause of the issue to identify if the issue is related to your original account itself such as ADFS or Single sign-on, it will be deleted in the coming days and cannot be used continually. We appreciate your understanding.

As the test account works fine, it indicates something is wrong with your original account, in this situation, could you provide us with the screenshot of the error message in the thread and the additional information of your account via private message?  To collect the additional information, I have sent you a private message, please reply to us so we can help you sort this issue out.

Best Regards，

hi stephanie,

thanks for your information in the private message.

given the error message, the issue may be caused by the missing certificates. so, i suggest you follow the steps below to install the organization’s certificate on your mac:

1. download the package archive.zip i sent via the private message.

2. open the package and double click “auscertserverca.crt” and “utnaddtrustserver_ca.crt”.

3. they will be added to your keychain access.

4. go to keychain access (finder > go > utilities) and select system, you will see the two added certifies “auscert server ca” and “utn-userfirst-hardware”. if they are not available, please drag the downloaded .crt files directly there.

5. double click on them one by one, click the trust discloser triangle to display trust policies and select always trust.

now please try whether you can activate office 2011 for mac with your account. please go to finder > applications > microsoft office 2011 > office and open microsoft office setup assistance, and you can try re-activating.

if the issue remains, please capture the error message and upload the screenshot here for our reference. to insert a screenshot, click on use rich formatting to create your post. on the edit page, select insert/edit media icon to upload a screenshot.
