Similar trouble here I've been running CCleaner for years without problems, on all my PCs ... but after updating to v5.27.5976(64-bit). This PC has Win7 Pro 64-bit as the OS, Current version CCleaner v5.28.6005(64bit) still crashes at around 56% (Mozilla Thunderbird) on my primary PC. Crashing @ 56% of Cleaner scanning Problem signature: Problem Event Name: APPCRASH Application Name: CCleaner64.exe Application Version: 5.28.0.6005 Application Timestamp: 58b9ab00 Fault Module Name: CCleaner64.exe Fault Module Version: 5.28.0.6005 Fault Module Timestamp: 58b9ab00 Exception Code: 40000015 Exception Offset: 0000000000150c96 OS Version: 6.1.7601.2.1.0.256.48 Locale ID: 1033 Additional Information 1: 3dae Additional Information 2: 3daeed5726aec294e4de57aeec9d2236 Additional Information 3: ef69 Additional Information 4: ef69b4ec505e1a0ff56092ebee30bc0e FWIW After reading others posts here, I unchecked the "compact database" option for Mozilla Thunderbird and it completed without crashing.
