Will cleaning the registry work. I tried the tool mentioned there but it needs registration.

Can this be resolved

Answer 1

I have resolved my problem. It was a critical one really.

Here is what happened:

The service I wrote crashes soon after starting. While crashing, it probably holds onto few resources and hence when I try to uninstall it, it wont be removed from the list of services, that is, it is never removed from registry.

Now that it’s still entered on the registry, I can neither install or uninstall it. The .exe has been removed in last un-installation, therefore there is nothing to uninstall.

The solution was to manually remove the entry from registry. I have changed my code so that it doesn’t crash or at least it’s handled as an exception.
