TargetFramework and inherits reference errors

Question

Since upgrading from Crystal Reports Distributable and CR2008 for VS2010 beta (version 14) to the final release (version 13), and redeploying my application, I am getting the following errors when I navigate to the website.  (Note that the application runs perfectly in the development environment).
On the default aspx page - which is just a menu of hyperlinks, no viewer component - I get an Web.config error indicating that the targetFramework directive is not recognized, and I have to change:
<compiltion debug="false" strict="false" explicit="true" targetFramework="4.0">
to
<compiltion debug="false" strict="false" explicit="true">
Then the default page runs perfectly, but the subsequent viewer page reports "Could not load the assembly 'App_Web_u1d2wxho'. Make sure that it is compiled before accessing the page." The page will load if I remove the inherits tags, changing:
<%@ page language="VB" autoeventwireup="false" inherits="_Default, App_Web_u1d2wxho" %>
to
<%@ page language="VB" autoeventwireup="false" %>
But when it loads, the Crystal Report Viewer is completely blank - apparently the report requested on the menu page is not being loaded into the viewer.
Any insights?  Thanks in advance.

Many thanks for creating a new thread on this issue. Just organizes the forums a bit and helps in searching, etc.
Anyhow, to the issue at hand. I have no idea what those error messages mean or why they are being thrown. But, let's glaze over the error messages for now and see how I'd go about deploying the app - perhaps there is something missing on your end.
1) Before we install the CR runtime, we want to make sure we have the correct framework installed on the server
2) If you are using .NET datasets, you will need framework 2.0 in addition to what ever framework your app uses
3) You do not mention how you deployed the CR runtime, but this being a web app, I'd use the MSI. Again, we must use the correct MSI:
32 bit:
http://downloads.businessobjects.com/akdlm/cr4vs2010/CRforVS_redist_install_32bit_13_0.zip
64 bit:
http://downloads.businessobjects.com/akdlm/cr4vs2010/CRforVS_redist_install_64bit_13_0.zip
The "bit" applies to the app, not the OS. E.g.; if the app is 32 bit and will run on a 64 bit OS, we need to install the 32 bit runtime.
4) If this is a 64 bit OS, and the app is 32 bit, the IE will have to run in 32 bit mode
5) If the app is in a default app pool, then all is good.
6) If the app is running under custom app pool, the CR viewer directory will not be correctly configured and you will have to do this manually as the MSI has no idea about what app pool the app will run under. Thus if you are using custom app pool, you'll have to copy the ...\aspnet_client folder and it's subfolders from the dev box to the server and make sure it is copied under your app pool.
