Hello, since using CCleaner on my Windows 7 computer, thumbnail pictures for Video files and PDF files seem to have stopped working, I now just get the file with no picture etc. Thumbnails for Jpegs are still OK.
This happened a while ago but I have only just decided to sort it out.
I have followed basic instructions to make sure thumbnails are 'switched on' with no change. I did this manually and also downloaded and run a fix to do this.
I cannot be certain that CCleaner did this but it happened about the same time.
Please note I am not a computer expert, any help would be greatly appreciated.
there have been at least 11 version of ccleaner since your version came out. Many bugfixes were included in those updates, perhaps a newer version fixes yo7r issue.
