Hi all, My computer is using Win 7, I could run these software before, but recently, I cannot. When I click it to run, it just show up few seconds in Task Manager. And close, and window doesn't show any message about error or what's happening. When I check Windows Logs in Event Viewer, at Application, I found these messages: Faulting application name: DTaskManager.exe, version: 18.104.22.168, time stamp: 0x47a80be8 Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000 Exception code: 0xc0000005 Fault offset: 0x0024258c Faulting process id: 0x1190 Faulting application start time: 0x01cc2a448f9e5a17 Faulting application path: G:\Software\[System] DTaskManager 1.51\DTaskManager.exe Faulting module path: unknown Report Id: d2f069a7-9637-11e0-a201-1c6f65bfd423 Fault bucket 2039211025, type 5 Event Name: BEX Response: Not available Cab Id: 0 Problem signature: P1: DTaskManager.exe P2: 22.214.171.124 P3: 47a80be8 P4: StackHash_3a51 P5: 0.0.0.0 P6: 00000000 P7: 0024258c P8: c0000005 P9: 00000008 P10: Attached files: C:\Users\thongnguyen\AppData\Local\Temp\WERF35D.tmp.WERInternalMetadata.xml Did anyone have this trouble before? please help me.
