Hi, we are having office 365 business licenses and installed the same in one of the laptop but while installation it gives some error and installation getting aborted. Then we removed project 2013 from that system and then able to install office 365 business. Now we again installed project 2013 but it is not showing any option to enter activation key instead of it showing to log in. 

Please Help.

Hi,

Is the Project 2013 a MSI version or click-to-run version?

Please also try the following steps and see if you can enter the activation key:

Open Control Panel and go to Programs and Features. Then, select Project 2013 and click Change button on the top of the screen. Choose "Enter a Product Key" and click Continue.

Please let me know the result.

Regards,
