Trying to create a fresh installation of MS Project 2013 post a system crash of Win 7 system - will not install on the same machine for a second time which is very unexpected!

Is it time or installation limited?

I have the original box and key - any ideas?

Hi,

Do you mind telling us the error message when you re-installed? As far as I know, we can re-install the Office on the same computer without any issues. We can read this blog about the new Office 2013 licensing terms

https://blogs.office.com/2013/03/06/office-2013-now-transferable/

Then, if we have the installation copy, please try to install Project 2013 first and skip the activation during process. After installation is complete, we can use your key to activate by phone.
