I installed v5.08 and immediately had problems with Windows 10 Pro locking up and quickly uninstalled it. When the new v5.09 was released I again installed it, and did a scan, all appeared OK till I clicked on Run, when the Green bar advanced to 16% and then stopped. It was trying to delete a file in my C drive... Windows 10 became unresponsive and I eventually managed to Uninstall CCleaner Pro again.
Sorry cannot remember the file it was trying to delete.
