LoadRunner Community Edition + TruClient error

Hi all,

I'm using LR Community Edition with a TruClient test i have recorded with VuGen.

I get the following error: 

Error occurred while trying call 3rd party license component. Error Message: 4002

I think LR is not being able to work with TruClient.  However, all protocols except DCOM and GUI should be included in the free edition.

I've not found anywhere error code 4002...

Any clues?

Thanks in advance
