Cant open any office files on computer

1. Would you please see if you can open the office program in user initiated safe mode
Use User-Initiated Safe mode

To start a Microsoft Office program in User-Initiated Safe mode:


On the Microsoft Windows Start menu

1. Click Start, point to All Programs, and then point to Microsoft Office.
2. Press and hold the CTRL key, and then click the name of the Microsoft Office program that you want to run.

2. Would you also check please the status of the Windows Installer service - please open Control Panel
admin tools, services or use the run cmd and type
services.msc

scroll please to windows installer service
is the service configured
manual start and shown stopped
please set it manual start if not using drop arrow on start type
then please try and start it.
Does it start please

If it does NOT start
Also please note a dependency is Remote Procedure call, - click the dependency tab on Windows installer service and check RPC
RPC should be automatic and running that is RPC and not RPC Locator

3. Which anti-virus do you use please.

4. If the above measures do not work we will have to rebuild the windows installer service.
