Missing/native Crystal Reports DLL load failures (the one shown in the OP) almost always mean the Crystal Reports runtime that supplies native components is either not available to the process or its architecture (x86 vs x64) does not match the application. As asked, it matters whether the error is on the dev machine or a client machine — installing the Crystal Reports designer in Visual Studio does not necessarily install the redistributable runtime. As noted, SAP has a Knowledge Base entry describing this exact class of problem and a workaround.

Quick checklist (most common fixes, try in order):

  • Verify the application platform and CR runtime bitness. For VB.NET set Target CPU to x86 (Project -> Properties -> Compile -> Advanced Compile Options -> Target CPU) or switch the build to the same bitness as the installed CR runtime. For IIS-hosted apps, set the app pool "Enable 32‑bit Applications" appropriately.
  • Confirm the Crystal Reports runtime redistributable (the runtime engine for .NET) is installed and matches x86/x64 (Control Panel -> Programs and Features). The designer install alone is not sufficient for runtime use.
  • Capture .NET binding failures with the Fusion Log Viewer (fuslogvw) to see which assembly binding is failing. Use Process Monitor or Dependency Walker to catch native "file not found" attempts for the native DLL.
  • Check all CrystalDecisions.* references for consistent versions and, if necessary, set the managed wrappers to Copy Local. Remember the native DLL is provided by the runtime package, not by copying the managed DLLs.

Typical resolution: set the project to the correct platform and install (or repair) the matching Crystal Reports runtime redistributable. If problems persist after those steps, the bind logs from fuslogvw / ProcMon will show the missing dependency and point to the exact fix.

Is this exception thrown from a client or the dev machine?

If this is from the client, you need to install Crystal Reports.
