One day, accidentally I ran into this thread on Reddit with similar issue. They assured me that nothing is wrong, office endpoints are definitely not blocked.Īt this point I was so tired of this issue, I started to instruct the user to switch to any other network that is not connected to company. Something is blocking Office suite and it is getting stuck.

I started messaging Networking guys, stating that there is some weird problem with the network. No matter how I tried, SaRa tool, Office Deployment Tool, the usual installer some machines just refused to install and always got stuck at 2%, 51%, 58% It is a huge chance it’s the firewall – At least it was for me.Īfter months of loathing, testing different scenarios, plain guessing, checking those gibberish installation logs, I noticed that when asked the user to connect to different network source – Wi-Fi or direct cable the problem seemed to solve. This problem was repeating itself for at least 30% of installations and I was seriously despising Microsoft for creating such a buggy installer. This became such a huge issue for me that I was getting so nervous, stressed, and sweaty when getting assigned a task to reinstall the Office suite for a user.
