Thanks I have fixed it after reading some posts about having to uninstall avg tuneup.
So went in to Control Panel\Programs\Programs and Features
double clicked avg turnup and instead of uninstalling it just clicked on repair from the popup
and clicked restart now and my office 2007 is working.
so if you do the same with Avast cleanup it should do the same as avast & avg are the same company.
I can confirm the fix provided works fine - Windows 10 Pro.
For those that need to help others via phone, but are not eloquent in providing verbal technical instructions, try installing Remote Desktop (Google) to remote into the problem PC. You can also enable Remote Desktop using the System Properties. Press the Windows Key and Type: advanced system. Click View advanced system settings. Click the Remote tab and select Allow remote connections to this computer. Keep the box checked for Network Level Authentication for better security.
Just so that you are aware that this problem hasn’t gone away, I have purchased snd ran Cleanup Premium and I cannot open any of my office files, unebelievable stuff.
This thread had the previous post in June which said it’s all fixed now, but we’re now in late september and nothing’s changed.
Abysmal company.
