类未注册(异常from HRESULT: 0x80040154 (regdbe_classnotreg))"在

我们使用vs2005和framework 2.0开发了一个windows应用程序。这个应用程序在32位操作系统上完美运行。现在我们需要为64位操作系统提供支持。

当使用64位操作系统时，我们得到以下错误信息:

"Class not registered (Exception from HRESULT: 0x80040154 .)(REGDB_E_CLASSNOTREG))"。

下面是代码块

System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(Driver));     
this.axDriver = new AxCCNAccess.AxDriver();     
((System.ComponentModel.ISupportInitialize)(axDriver)).BeginInit();     
SuspendLayout();     
//     
// axDriver     
//    
axDriver .Enabled = true;   
axDriver .Location = new System.Drawing.Point(241, 211);   
axDriver .Name = "axDriver ";    
axDriver .OcxState = ((System.Windows.Forms.AxHost.State)(resources.GetObject("axDriver .OcxState")));    
axDriver .Size = new System.Drawing.Size(41, 42);     
axDriver .TabIndex = 0;     
//     
// Driver     
//     
AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);    
AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;     
ClientSize = new System.Drawing.Size(292, 266);     
Controls.Add(axDriver );   
Name = "DriverContainer";  
Text = "DriverContainer";     
try     
{
((System.ComponentModel.ISupportInitialize)(axDriver )).EndInit(); 
}    
catch (Exception ex)  
{
string sss = ex.Message;
}
ResumeLayout(false);

try块中出现问题
