Haven't specifically tried to empty Recycle Bin, though it is ticked as a regular cleaning task along with many others. And I don't have a floppy drive. However CC 3.11 analyses OK but crashes when attempting to clean. Below is a copy of my Event Log Viewers account of the situation: Faulting application name: CCleaner64.exe, version: 126.96.36.1991, time stamp: 0x4e7b96bf Faulting module name: USP10.dll, version: 1.626.7601.17514, time stamp: 0x4ce7c9f5 Exception code: 0xc0000005 Fault offset: 0x000000000006db75 Faulting process id: 0x1644 Faulting application start time: 0x01cc7d81242d9241 Faulting application path: C:\Win\PiriForm\CCleaner\CCleaner64.exe Faulting module path: C:\Windows\system32\USP10.dll Report Id: 89732b18-e974-11e0-9bb2-1c6f659355ad Have reverted to 3.10 pending a resolution. Might as well add a big thank you to PiriForm for all the other versions that have worked just fine for me.
