[RESOLVED] Error: "No connection could be made because the target machine actively refused it"

[edolf8]

Hi Everyone,

So I had my program working, and then after I made some substantial changes I uninstalled the program, and tried to reinstall the updated program. When I clicked on the install program, a window popped up that said:
"Application download did not succeed. Check your network connection, or contact your system administrator or network service provider."
When I click the button to see more information, I get a text doc with this information:

I have scoured the internet for what I changed that caused this error, but I cannot find anything! My program pulls information from an Excel file, and then outputs it to a datagridview and chart on the form.
I am not trying to make this a webservice, or available on the web. I am trying to put the program where it previously was, and it successfully installed. I made very superficial changes to the program, and I don't think I changed anything in the application settings. Any help would be greatly appreciated!!!

[mebhas]

stupid question, but did you check the firewall settings?

[edolf8]

Hi Mebhas,

I am creating this program on my computer at work, so I do not have access to changing the firewall. However, I was previously able to install this program (as recently as a week ago) and as far as I know the firewall settings have not been changed recently (A computer administrator has to do it, and no one has logged onto my computer besides me in more than a month).
Would the firewall all of a sudden start blocking it, if it did not block it before? Thank you for your help!!!

[mebhas]

of course not, unless the port has changed.

The only reason I have seen for this error, so far, is firewall settings.

Where is this "http://erandolpdxp/" machine? Is it something in the network or is it your machine? It still does not hurt to check the firewall settings in that "http://erandolpdxp/" machine.

I'm still not sure how or why the output URL changed. It is supposed to go to this file path: "H:\HONDA EDI\830\HMIN\EDI Reader". The program is successfully published to this spot, but when I try to install it to the same place is where I run into the error.
I even tried having it published to somewhere different from where I was installing it, and I was getting the same error. As I said before, I have no idea why it started sending it to "http://erandolpdxp/HMIN 830 Reader/HMIN 830 Reader". Is this something I need to fix in the Project Properties in VB2008?

Thanks!!

[mebhas]

Yes, you need to check the deployment/publish settings for the project.

Another thing to double check is this:
you are doing a remote download and install from a "server" called "http://erandolpdxp/". If this is the right place (and by your response, it is not) make sure the IIS is configured properly (which is not required if this is where the application installer is hosted).

It will also be very helpful to have a look at what your project settings are when you publish the project.

[edolf8]

Urghhhhhhh!!!!! I figured out what I did wrong:
If you go the "Publish" tab in "Project Properties", click the "Options" button, and go to the "Manifests" tab, there is a check box labels "Exclude deployment provider URL". I guess I unchecked this box at some point while manipulating the settings, and this is what caused me so much grief over the past 3 days!
Thanks Mebhas for guiding me to look at the settings!

no problems, happy to help
