Report works fine in VS2010 but simply doesn't show when published

Question

Problem:
Crystal Report works fine in VS 2010 but doesn't show when published to web-server, there is no error, it simply doesn't show.
Background:
Installed VS2010 on a freshly installed and fully updated (.net 4.0 is included in the updates) windows server 2003 box with production release Crystal Report 2010. Nothing else is on the server.  IIS 6 is running.  My web-server and VS2010 is on the same box.
I went ahead and created a new asp.net 4.0 web project called webapplication1. Thereafter, i put a few controls (text-boxes, list-boxes and so on)  on the default.aspx page. Then i created a report.aspx page. This page will have the crystal report viewer on it. I went ahead and set the report up without much hassle (got how-to's from the internet).  I successfully tested my web app with the built-in testing server, the beautiful crystal report presented exactly what i asked it to. There was one recurring "Sys.Application is null or not an object" hiccup that occured every time during testing when i navigated from the default.aspx page to the report.aspx page (the page the report is on). Clicking ignore or continue  on the dialogue box that comes up because of the hiccup will allow testing to continue.  Here's a screen-shot of this recurring hiccup.

As i've shown, testing went great, except for the hiccup. I now moved to setup a publish profile. Since my web-server and VS2010 is on the same box this seemed relatively straight forward. All the files went over except the report, i.e. crystalreport1.rpt  file. I solved this by  setting the build action to 'Content' in the CrystalReport1.rpt properties. I did a republish. Now i have all my files, see screenshot: [http://i440.photobucket.com/albums/qq122/ricom_19/Application-Home-Directory.jpg], on the web-server.
I proceeded to try to browse to my app from another computer on my network. This was successful until i tried to navigate to the report.aspx page that the crystal report is on. The the report.aspx page loaded but the crystal report was simply not on it. No errors, not even the hiccup from testing occured. Its as if the crystal report viewer was never on the page to begin with. Only when i right clicked on the page and 'view source'  did i see some remnants of the crystal report viewer.
Here is the Report.aspx page when tested in VS2010:

Here is the Report.aspx page when published to the web-server and browsed to from another computer on the network:

Details of adding report to my web app:
1) Populate my dataset then write the XML schema, reportschema.xml
2) Added the crystal Report to the project then used the wizard to navigate to the reportschema.xml. Of course i had to create new connection in Database expert. see screen-shot:

3) I formatted the report the way i wanted it
4) Added the Crystal report viewer on the Report.aspx page
5) In the code-behind of the Report.aspx page i bound the viewer to a report document that is loaded with CrystalReport1.rpt file

That's it.  As mentioned, it tested fine in VS2010 but the viewer doesn't show when i publish to the webserver. I wrote a crystal report in .net about 8 years ago. Things have changed soooo much since then.
I am wondering if its a license issue? Was also wondering if it had anything to do the testing hiccup, even though research is suggestion the two are unrelated.
I've described my actions as best as i could (without getting into ridiculous detail) and have included screen-shots of relevant stages of the process. Have a look and tell me your thoughts. Thanks.

The "Sys.Application is null or not an object" issue is known, submitted for a resolution and documented in KB #1528503. Unfortunately the KB search has been down the last couple of days...
However, the issue is limited to compile time and does not affect a completed application.
Re. the viewer missing. Sounds like the viewer directory did not get created or configure correctly. Before I get to that. You mention:
"I proceeded to try to browse to my app from another computer on my network."
This bring up the question: If you run the app right on the app server. e.g.; not a client computer, does the viewer and report come up? Is this issue isolated to client computers on the network?
I suspect that the issue exists irrespective of which computer you try to see the report from - but that is an assumption. If the assumption is correct, see [this|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/50aa68c0-82dd-2b10-42bf-e5502b45cd3a] article on configuring the viewer. The article does not have CR4VS2010 documented, but you should be able to guide your self using the article. I think the pattern will be obvious.
