Exception while creating snapshot - dotTrace performance

Hello Community,

I am using dotTrace Performance 5.3 and have been very satisfied with results and work, but since two weeks I have serious problems.

First I was not able to get SnapShot in “sampling” mode anymore but “tracing” works fine, now “tracing” mode as well throws exceptions, after clicking “GetSnapShot” button.

--> Exception text is attached as txt file.

I need your help very urgent.

Does anybody knows this problem or has Idea how to proceed… what to do to get snapshots again.


Configuration: Win7 x64

The program which needs to be traced contains C# and mixed mode C++/cli and native dlls. The traced process runs as child process.


Any idea or tip?

Many thanks in advance.


Best regards,
