CRVS2010 Beta - 'Sys.Application' is null or not an object

Question

I have been attempting to create an ASP.NET Web Application in C# which includes Crystal Reports. However, as soon as a CrystalReportViewer is so much as added to a blank project, I begin receiving the following error:
Microsoft JScript runtime error: 'Sys.Application' is null or not an object
The error is being called in crv.js. According to the research I've done on the topic, Sys.Application is not initialized until execution reaches the </forms> tag. I've only been able to find one other person complaining of the problem who uses Crystal Reports (although there are quite a few who get it from ComponentArt, which I don't use), and he claims to have fixed it by editing crv.js, but I can't find that file and I'm sure there must be another way if so few people are encountering this error.
I have to assume I'm missing something obvious. Can anyone help?

Answer 1

Thank you very much!
As I mentioned earlier, I cannot figure out how to edit the .js file. Somehow, there are 6 files named crv.js on my hard drive, and I am not sure which of them to edit; there is no copy in the actual project, and I already tried editing the one in C:\Program Files (x86) to no effect.
I'll try editing them all once I'm finished re-installing CR.
EDIT: Editing C:\Windows\Microsoft.NET\Framework\v4.0.30319\ASP.NETClientFiles\crystalreportviewers14\js\crviewer\crv.js had the effect I was looking for. Unfortunately, a try-catch block somehow caused "'bobj' is undefined" errors, so instead I edited the code to read:
if(typeof(Sys.Application)!=='undefined') {
    Sys.Application.notifyScriptLoaded();
That stopped the problem. Thank you for all your help!
