I suspect you have missed the first part of the error message and are just providing the "InnerExeception", never the less. I Googled Error: 80040154 Crystal Reports and got the following result for you:

I had a similar issue before and for me it was where I was creating a 32bit application but had installed the 64bit crystal reports. Ensure that your versions match and that your application is compiling to the correct target platform.

Solution 2

SQL

You dont have to configure your project properties platform target X86. You can also configure the iis options to work with x86 like that

    * Select Application pool
    * Select the pool which your app uses
    * Advanced settings
    * Enable 32 bit applications true
