I've playing Age Of Empires 3 for a while and it works fine on my system. I recently build a new system and install AOE3 from scratch, but it crash with APPCRASH and the error log showed that the problem is with a file C:\Windows\SysWOW64\ntdll.dll. I reinstall again and applied the 1.14 patches, but still stopped by the same error. I provide the info below hoping that somebody can give my any idea how to resolve the problem. My new system: Windows 7 SP1 (moved from old system), Intel Core i7 2600K, ASRock Z68 Extreme4, Corsair 4GX2, Gigabyte GTX560Ti. All drivers are updated from official sites. The Windows 7 is from old system but updated by Windows auto-updates. After I finish building the new system, I move the hard disk from the old one, boot to save mode and install all the drivers of the new hardware, Scanned for Windows update again. Every thing works fine in the new system except AOE3. Here is the problem info: Crash message (pop-up when AOE3 stops): Problem signature: Problem Event Name: APPCRASH Application Name: age3.exe Application Version: 4.107.803.3366 Application Timestamp: 49ef2fda Fault Module Name: ntdll.dll Fault Module Version: 6.1.7601.17514 Fault Module Timestamp: 4ce7ba58 Exception Code: c0000005 Exception Offset: 0002e046 OS Version: 6.1.7601.2.1.0.256.1 Locale ID: 3076 Additional Information 1: b7d5 Additional Information 2: b7d52c2e5860ea20297315ff90f99ea5 Additional Information 3: f507 Additional Information 4: f507b7974b4143f4b5cac82533508512 Application log from Event Viewer: Faulting application name: age3.exe, version: 4.107.803.3366, time stamp: 0x49ef2fda Faulting module name: ntdll.dll, version: 6.1.7601.17514, time stamp: 0x4ce7ba58 Exception code: 0xc0000005 Fault offset: 0x0002e046 Faulting process id: 0x131c Faulting application start time: 0x01cc390a888a463c Faulting application path: C:\Program Files (x86)\Microsoft Games\Age of Empires III\age3.exe Faulting module path: C:\Windows\SysWOW64\ntdll.dll Report Id: c989dc7d-a4fd-11e0-a4ac-002522c3e76f
