Windows 7 desktop machine,works fine. Adobe Reader DC installed to handle .pdf files. Since the last batch of Win Updates it appears something has been broken.
Clicking on .pdf files brings an error message.
"The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail." I have no idea what this means. I uninstalled Adobe and reinstalled it. No difference.
Can anyone help please.
