drltrace unable to track executable #31

Closed MrVoustache closed 3 years ago

MrVoustache commented 3 years ago

When I try to track an executable on Windows 10 (my drltrace version is "drltrace custom build -- May 5 2021, 10:09:57". I used the instructions on the How To Build page, for Windows 10 64 bits, and thus I have the included DynamoRio version I guess), I get this issue: When I try to track a Windows application (calc.exe, explorer.exe...), the tracking stops before the application shows up : drltrace.calc.exe.10636.0000.log

On the other hand, when I try this with a not native application, the application does not start, and I get this message (and no log file). And the application starts normally through PowerShell. Here I tried with audacity: PS C:\Program Files (x86)\Audacity> & "C:\Users\admin\Documents\Savegames\build\bin64\drltrace.exe" -- .\audacity.exe WARNING: cannot write log file into C:\Program Files (x86)\Audacity, writing log into C:\Users\admin\AppData\Roaming\Dr. LTrace instead INFO: C:\Program Files (x86)\Audacity\audacity.exe sucessfully started, waiting app for exit

Here is the executable: audacity.zip But I got the same issues with python3 and steam for example... Thank you for your help

Ah, I see the problem. I didn't run your binary but the problem with Steam is that it is 32-bit application. You need to use 32-bit drltrace for 32-bit applications and 64-bit drltrace for 64-bit applications.

Ah yes, indeed, It works better with the 32bits installation! I tried with the two installations and it seems to be working just fine now. Thank you very much!
