I upgraded the version I had before (no idea what it was) to the latest. When it was installed I ran it and it gave a distorted main screen, that is the main screen without buttons, text, or any interactivity. Then it started a series of flashing screens with minin windows with white border also flashing then finally ending up with the main screen, ghosted out with a 'optional advertisement to keep CCleaner free for everyone' and then the laptop locks up unresponsive. my pc versions works fine with no sign of the 'advertisement'.
- both were downloaded from this site
- both OS are Windows 10 fully updated to today
- laptop was scanned via SFC/DISM/chkdsk and only SFC found problems and fixed them.

Anyone seen this or something similar before?

Obviously that is not normal.
And I've never seen an advertisment like you describe - but there is always a slight chance that it's something new.
If you are using an Antivirus other than Windows Defender then please tell us what AV it is and what version number it is.
Some AVs can interfere with CCleaner, particularly if/when the AV is not up to date.
Note that some will say 'up to date' when in fact they are not, which is why we want to know the AVs version number.
PS. I have just downloaded a new installer from the link in 'Announcements' and reinstalled CCleaner on this laptop, it's working just as it should do.
