Can I open my 32bit app in 64bit office 2010

[Jackxxx]

I'm trying to open my Access 2007 database app in office 2010 64bit. I get a message that tells me I need to delete all my code in order to open the app.

Are we required to rewrite all our code to support 64bit Access?

What I've found is that 64-bit Access wants the keyword ptrSafe, which 32-bit does not recognize. Here's one way I have been able to maintain one system that works on both versions:

#If VBA7 And WIN64 Then
        Private Declare PtrSafe Function ....
#Else
        Private Declare Function ....
#End If

Its a real pain and has to be done for every function declare.
