windows service installed as 64 bit, but run as 32 bit

Question

I have created a windows service with some third party dll's. Those dll's are all 64 bit so I need to set the project to 64 bit and install the service with the 64 bit installer. This all works and is not a problem.

However when I start the service it gives an error on one of the dll's. An Acces Violation Error.

I got this error before when I tried to run the code as 32 bit in another program.

I also copied all code to a simple windows form. There it works like a charm... So it seems to me that for some reason, Windows tries to start the program as a 32 bit program? Is this possible?

I must say, I'm a bit of a noob when it comes to programming...

Edit: It does show as a 64 bit program in the task manager: Platform in Task Manager

Below the error I get: My error

Hope this helps.

Answer 1

There is a bug in the Dll which gave this error. It now lies by the supplier. I thought, i'd let you know.
