Vs2008 compiling arcengine on 64-bit Windows platform causes hresult: 0x80040154 (regdb_e_classnoregulatory) Error solution.Favorites

Vs2008 compiles arcengine (9.3sp1) in a 64-bit System (XP, Vista, and win7) and prompts when running:

No registration class (exception from hresult: 0x80040154 (regdb_e_classnoreg ))

Cause: arcengine9.3 does not support 64-bit native, but runs in 32-bit compatibility mode.

Solution: In the project properties, set "generate" => "Target Platform" to x86 instead of the default any CPU.

ESRI officially solves this problem:

BUG: Error: class not registered (exception from hresult: 0x80040154 (regdb_e_classnoregulatory)

Article ID:	33000
Bug ID:	Nim007516
Software:	ArcGIS Engine Runtime9.2, 9.3
Platforms:	Windows2000, XP

 

Descriptionrunning an application from Visual Studio 2005 on 64-bit computers, displays the following error message:

"Error: class not registered (exception from hresult: 0x80040154 (regdb_e_classnoregulatory )"

Causewhen running a Visual Studio Application, the default Common Language Runtime (CLR) platform in the Visual Studio is set to any CPU. this default must be changed on 64-bit computers to compile the assemblies with the 32-bit, x86 compatible CLR. workaroundchange the default platform target CPU to allow applications to run on 64-bit machines:

1. Right-click on the solution in the Visual Studio Solution Explorer and open the Properties window.
2. Click the compile tab: Visual Basic, or the build tab: Visual C #.
3. For Visual Basic, click the Advanced tab.
4. Select x86 as the target CPU (Visual Basic) or platform target (Visual C #).
5. Rebuild the solution.
