I&#039;ve had just all kinds of errrors when trying to run Crystal Reports on this testing server. From license issues, to conflicts between 9.2 and the .NET 9.1 dlls, to now this...<BR><BR>When calling any report from an ASP.NET page I get the "Common Language Runtime detected an invalid program" error. Ok, so I&#039;ve been doing research on this error and it seems as though there&#039;s a problem with the line in the aspx file that calls the CR viewer so I assume there&#039;s something up with Crystal Reports on the server itself. However, I cannot find a single web article that describes this error in detail and how to correct it.<BR><BR>When using CR do I need to package something in particular for installation on the server? I&#039;m not getting this error on my dev boxes, only on the server. I&#039;m sure I&#039;m not explaining this very well, so please let me know if I need to expand on something.<BR><BR>Thanks.<BR><BR>
