I am not quite sure I understand your scenario here. Could you please give me some more details about what you want to achieve (maybe exemplify)?
If I understand correctly, you want to stop a service when the installation begins and then restart it when the installation ends? Please let me know if this is the case, otherwise please give me some more details.
How weird is this post, where is the rest of the posts from the other user that created the thread, this is not my thread, however I was replying to someone else. Odd!!!
This is, indeed, strange. I have found this topic in the "Feature Requests" forum and I have moved it up here. However, it was a completely new topic, not a reply to an older topic. Probably, this is why I did not understand well what you wanted to mean, because the thread was totally out of context.
Please let me know if I can still assist you with something here.
