Solidworks Addin Debug problem in 64 bit machine

Hi

I am facing one problem with solidworks addin.

I have created one sample solidworks addin in VB 2005.When I am building the assembly it gives the follwing error.

error MSB3216: Cannot register assembly"Assembly path"- access denied. Access to the registry key 'HKEY_CLASSES_ROOT\\TMXSWA_GenericFormProject1.BitmapHandler' is denied.

When i have registered the assembly by regasm tool.it is registered and shows in solidworks addin list.

But i want to debug the Addin.Is there anyway to solve this problem.

I am new to 64 bit environment.

can anyone help me out.

Regards
