I am a software developer not associated with this company. From a technical support viewpoint, when a user submits a possible issue, I look to see if the issue had previously been reported and resolved then I send the user that link, which in this case was done. So, the response was the correct one to begin with.
Only when the issue appears to be more widespread do I spend more time looking into it, as this issue has proven to be a widespread one as demonstrated by the number of reports in a single day.
When you develop a software package that depends on other software and vendors, you cannot always anticipate when a software change in the other software will impact your software.
From the view of a technical outsider, it would appear that Chrome made a change that impacted CCleaner.
We did our jobs and brought it to their attention. We now need to give the developers a chance to investigate and resolve this issue.
