Intel GPA Shim Loader(shimloader64.dll) calls SetDllDirectory(). That causes "ERROR_MOD_NOT_FOUND" on some app.

Hi. I'd like to use Intel GPA for UnrealEngine4. but I couldnt. Becuase Shim Loader calls SetDllDirectory() that override UE4 engine's setting(SetDllDirectory to set project directory for load dll directory). Could you check this out?

Hi Changmin, 

Sorry that you are running into this issue with the Shim Loader.   Let's see if we can get to the bottom of this one. 

Could you post your about dialog?  Graphics Monitor -> About (please post all the info in the window)

Also, are there any error files or logs you could supply?  Also, what version of the UE4 engine are you using?

Thank you for all the info!

Best,

Seth

Any app (include ue4) can use SetDllDirectory() to load required modules and SetDllDirectory() changes the standard DLL search path.

(https://msdn.microsoft.com/ko-kr/library/windows/desktop/ms686203(v=vs.85).aspx)

Becasue Those app depends on changed dll search paths, if GPA calls SetDllDirectory(), GPA breaks app's loading dll precedure.

Thanks!

Hi Changmin, 

Thanks for all the info. 

Are you using "Analyze Application" to launch your application or are you using the auto-detect functionality of monitor?

Thanks,

Seth

[Lee__Changmin]

Hi Seth,

I tested both. both of them cause the problem.

Thanks,

Changmin.

ps. That problem can be avoided by adding our game dll directory to environment PATH variable for my UE4 project.

Alright sounds good.   At least you have a workaround for the time being.  I'll submit a defect regarding this post and keep you up to date on a possible fix.

Hi Changmin, 

I have private messaged you with an unreleased build that should work to fix this issue. 

Best,
