How to take VS 2005 Windows App Build for Windows 7.0 64 Bit ?

Go to Project Properties, Compile, Advance Compile Options and in Target CPU change from Any to X64

I am  using MS Access DB as local database and using OLEDB Drivers.

On building the deployment application, i am facing an errror message as follows ..
oledb32.dll should be excluded because its source file 'c:\Program Files\Common Files\System\OleDB\oledb32.dll' is under Windows System File Protection

You can Exclude OLEDB32 from your installation project.  Since oledb32.dll is already installed, your program will be able to find and use it on the other computers.

Look at this post for more references and will be usefull for you

On removing oledb32.dll, my application is not able to connect or interact with MS Access DB

At present, i am deploying by removing oledb32.dll.

Application works well in any 32bit Operating System.

On deploying on 64 bit Windows 7.0 OS, application is not working.

Unfortunately, this application has to be deployed on Windows 7.0 64 But OS ( Atleast 5 Laptops )

I think that is because the location of the OLEDB dll is different on x64 Which one is the error that give the application??

I guess so,

Now to find Oledbd32.dll in Windows 7.0

Or how to copy and paste Oledb32.dll

or

Do we need to have something like Oledb64.dll for 64 bit processor ?

I hope you might be having an idea about GAC


How to copy a dll from GAC and place it on Windows 7.0 ?

I am just thinking of copying a Dll from here and place it over there ..

This One explain more or less something similar

Thats really a very good website which i look for ..

But i feel hard to understand .. my apologize.

So,

1)
We’ll need to  execute the command below from a command line or Start/Run :
Step 1: - On Windows 7.0 Command line
C:\Windows\syswow64\rundll32.exe "C:\Program Files (x86)\Common Files\System\Ole DB\oledb32.dll"

Whether this will work ?

Actual Error is

Microsoft.Jet.OLEDB 4.0 is not registered on Windows 7.0 64 Bit Operating System

Did you compile the Application trying to say that will be x86 CPU Targeting and install in the X64 computer. This must work find. Try to do this
Go to Project Properties, Compile, Advance Compile Options and in Target CPU change from Any to X86

and install in the computer with X64. DO NOT PUT ON THE COMPILE OPTIONS ANY

I did that .. Interestingly OLEDB 4.0 or 12.0 is not Supported by 64 Bit OS
