You will be prompt with a window, click “Install” Go to SaRa Tool, click “Download”, save and execute the file. You can use this list for any firewall you use in your environment. By whitelisting them in Sophos Exclusions the problem was gone! I have immediately sent an e-mail to the networking guys with KB’s and how-tos, begging them to implement.Īpparently, in our case, Sophos Firewall was inspecting Microsoft packets for too long and the office installer was timing out all the time. One user noticed that when specifically whitelisting all known endpoints in the firewall the issue was gone. 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.
