Hi All again<br><br>After a little search I have found an answer @ www.dotnet247.com, from Todd Acheson. <font style="color:990000;">Many Thanks!</font><br><br>Here it is:<br><br><font style="color:000099;">After a few hours of research and testing, I found the answer to my<br>problems. Listed below is a solution if anyone else is interested.<br><br>Steps to Deploy a ASP.NET WebApplication w/Crystal Reports<br><br>1. Preinstallation requirements:<br>A. You must have the DotNet Framework installed on the target<br>webserver. If you want to include dotnetfx.exe as part of your<br>installation, you will have to use something like the bootstrapper<br>sample application that Microsoft has published. Go to this article for<br>more information (watch for word-wrap in the text below!):<br><br>http://msdn.microsoft.com/library/en-us/dnnetdep/html/vsredistdeploy.asp<br>?frame=true<br><br>You will need to make a few property changes to your deployment project<br>before you make the final BUILD, along with some settings in the<br>setup.ini file that comes with the bootstrapper.<br><br>B. If your project involves any kind of data access, you will also<br>need MDAC 2.7 (mdac_typ.exe). This can be downloaded free from<br>Microsoft. If you want this to be part of your intall, you're on your<br>own here. You will probably have to make a custom setup.exe program,<br>similar to the bootstrapper application. The source code is available<br>from MS for this bootstrapper, but it's in C++. Installing mdac_typ.exe<br>will usually involve a reboot of your server. For this reason alone,<br>you may want to attempt this process during non-business hours, to keep<br>your users downtime to a minimum, if your users are using the server for<br>other purposes.<br><br>C. You must be familiar with how to deploy an ASP.NET Application.<br>For directions on how to do this, the following article can be found<br>under walkthroughs in Visual Studio.NET help or go to (watch for<br>word-wrap in the text below!):<br><br>http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vsintro<br>7/html/vbtskdeployingwebsolution.asp<br><br>In this example, my ASP.NET application was developed on Windows 2000<br>Pro, and was deployed to Windows Advanced Server 2000. We use crystal<br>reports to generate exported PDF documents, that are streamed to a new<br>browser window. To make our application functional, we also need the<br>Crystal components, dlls, etc installed on the web server.<br><br>WARNING: There are licensing issues when you deploy an application with<br>Crystal Reports. See link below (watch for word-wrap in the text<br>below!):<br><br>http://msdn.microsoft.com/library/default.asp?url=/library/en-us/crystlm<br>n/html/crcondistributingcrystalreportsruntime.asp<br><br>Here are the steps:<br><br>Follow the directions in "Walkthrough: Deploying a Web Solution"<br>(mentioned above) with the following adjustments:<br><br>1. Under the heading "To add the output of the WebApp1 project to the<br>deployment project", NOTE the following: My application has three(3)<br>generated DLLs. I have the the main dll generated for my web project.<br>I also have two(2) business (Database) layers that each get their own<br>dll. (My solution has a total of three(3) projects under it) All I had<br>to do was select the "Primary Output" and "Content Files" from my MAIN<br>dll, and the others were added as dependencies automatically. You can<br>verify this by visually noting the other dlls under the distiribution<br>project in your solution explorer.<br><br>2. Under the heading "To set properties for the installer", after you<br>perform step 2, do the following:<br>A. Click on Project --> ADD --> Merge Module... From here, you will<br>get a file browse dialog box that should default to C:Program<br>FilesCommon FilesMerge Modules. It is in this location that you will<br>find the necessary files to add.<br>B. Add the following Merge Modules:<br> 1. database_access.msm<br> 2. database_access_enu.msm (if you're doing the english version)<br> 3. regwiz.msm<br> 4. If you don't see a reference to managed.msm in you solution<br>explorer, you will need to add this file as well. It was there by<br>default when I added my Primary Output and Content Files.<br>C. Click Open on the dialog box and the files will be added.<br>D. Select the regwiz.msm file in you solution explorer.<br>E. In the Properties window, find the property (MergeModuleProperties)<br>and click the + sign to expand. You will need to enter your Crystal<br>Reports License Key in the License Key field. Where do you find this?<br>Click on Help-->About Microsoft Development Environment. Here you will<br>find a list of your installed VS.NET products. Select Crystal<br>Reports.NET. Click on Copy Info. Open Notepad. Click on Edit-->Paste.<br>Copy the key portion of the pasted string and paste it into the "License<br>Key" property under (MergeModulesProperties). Failure to do this will<br>cause an error during the Build process. You may have to register your<br>copy of Crystal Reports.NET, with CrystalDecisions, before this key will<br>be available (I did).<br><br>3. Proceed with the rest of the Walkthrough.<br><br>I installed my msi file on the web server, that only had the DotNet<br>Framework and MDAC 2.7 installed.<br><br>When you try to run your application in a browser window, you may get<br>the error "Server Application Unavailable The web application you are<br>attempting to access on this web server is currently unavailable.<br>Please hit the "Refresh" button in your web browser to retry your<br>request."<br>If this happens to you, check out this article in the MS Knowledge base<br>(watch for word-wrap in the text below!:<br><br>http://support.microsoft.com/default.aspx?scid=kb;en-us;Q315158<br><br>This article will tell you how to resolve the problem.<br><br>That's it.<br><br>I hope this helps other developers who were tackling these same issues<br>with installation of web apps and Crystal Reports.<br><br>Todd Acheson<br>Sr. Programmer/Analyst</font><br><br><br>Salut<br>redM
