Known Issue: Error booting Office apps for Insiders (Fast/Slow) running 1806, 1805 and 1804 Builds
· Impacted applications: Microsoft Office 365 Desktop Clients (Word, Excel, Outlook, etc.)
· Impacted Versions: 1806 (builds 10205.xxxxx, 9327.xxxx),1805 (builds 9330.xxxx) and 1804(builds 9266.xxxx)

Some users may get an error on booting Office apps. You might get a message when trying to launch Office applications indicating that you should launch in Safe mode and then the application fails to launch properly.
We have enabled a server side setting that will fix this issue. However, some users may still experience the problem if the client hasn’t picked up the new setting. We have released updated versions of the clients that address this problem.
Fixed Versions: 1806 (build 10211.20004), 1805 (build 9330.2053) and 1804(builds 9266.2156)
Clients will automatically download updates over time, however, if you want to update immediately you can trigger an update:
Office Click to Run:
1. Open any Office 2016 app, such as Word, and create a new document.
2. Go to File > Account (or Office Account if you opened Outlook 2016).
3. Under Product Information, choose Update Options > Update Now
Note: if you can't launch any applications, you can do an online repair of Office - see instructions here
Or a user can run this from a command prompt to force an update:
"c:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update user
Office in the Microsoft Store:
1. Shut down all Office Applications
2. Go to Microsoft Store and check for updates
In the event that you are unable to update at this time, there is an immediate workaround by deleting some registry keys. The easiest thing to do is:
· Open notepad, and paste the following text into the blank notepad
Windows Registry Editor Version 5.00
· Save it as LicenseMitigation.reg somewhere easy to find (e.g. on your desktop)
· Double click LicenseMitigation.reg and say yes to the prompts asking if it is allowed to execute.
