Moving to WIn 7 x64 generates bunch of compile errors in Designer!

Question

I support small local customers with VB2008 and MS Access applications (not VBA!). When I had to replace my machine, the new one came with Win7 64bit. Things failed immediately. I figured out how to compile VB for x86; but when I did that, I got a bunch of compile errors from the designer code, not my own. Typical of the errors is this one: ===Overload resolution failed because no accessible 'Add' can be called with these arguments: 'Public Function Add(name As String) As System.Data.DataTable': Value of type 'Lozier01_PaintInventory.ds.InventoryDataTable' cannot be converted to 'String' 'Public Sub Add(table As System.Data.DataTable)': Value of type 'Lozier01_PaintInventory.ds.InventoryDataTable' cannot be converted to 'System.Data.DataTable'. ===This is really frustrating -- can anyone explain what's happening and how to fix/avoid/work-around it? Many thanks, Stephen

Answer 1

1) You may have files in your project that are hard-referened to the system32 directory (which is now your 64 bit system directory) when in-fact they are located in C:\windows\SysWOW64 (now your 32 bit directory).

2) Also you may have files that your code is expecting to be registered to the GAC, but are not there either.

I hope this helps you.
