Finally, i found the solution.
It was the K Lite Codec Pack. I dont know why but I just uninstalled it and now CCleaner is working normally.
Thanks for your support.
Hello. Yes, I sent the report. No answer
I use Windows 7 Ultimate SP1.
AVG Internet Security 2015
Problems started with the "v4.19.4867" version (or "v4.18.4844" I´m not sure), and with the latest version, "v5.00.5050" it keeps happening
Thank you
Hello. I've been using Ccleaner for a long time and never had a problem until recently that it started giving an error, as you can see in the picture . I uninstalled it and reinstall and still not working.
Hope someone can help.
Thanks.
