Background installation ran into a problem

Hello,

I just bought the Word 2013 version. And everythings starts installing normaly
At approximatively 75%, something pops out and says:

Background installation ran into a problem
please make sure you're still connected to the internet, or try etc....

I just read everything about it. I run the fix it (opened it from the desktop).
I turned off my firewall.

In the beginning. It didn't wanted to start the installation. Now, at least, it goes to 75%... why... After this pops out. It strangely continues loading in the background. Then it finishes at 100% and that's it. But the error window is still there. I tried it several times and it is always the same.

Ok here are some additional things. I have the White Label Office installed, as well as the Outlook App.

I didn't used ANY product like Microsoft Office before.

In the folder Programms (x86)/ Microsoft Office / Office 15/ 
I found a SLERROR.XML and 5 out of the million lines are like this:

<err0xC004D30D>The security processor has reported that the secure timer name is too long.</err0xC004D30D>

<err0xC004D30E>The security processor reported that the trusted data store is full.</err0xC004D30E>

<err0xC004D309>The security processor has reported that the machine has gone out of hardware tolerance.</err0xC004D309>

<err0xC004D307>The security processor reported that the maximum allowed number of re-arms has been exceeded.  You must re-install the OS before trying to re-arm again.

<err0xC004D307>The security processor reported that the maximum allowed number of re-arms has been exceeded.  You must re-install the OS before trying to re-arm again.


Please give me some help on that, I start beeing frustrated...

All the best,

Alex
