Hi,

Based on my research, I found a known issue, you may have a try to see if that works for you.

<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>
When attempting to upgrade a VB6 project to VB2005 on a 32bit machine, the
following error is displayed as the wizard is initializing:

Unexpected exception occurred during upgrade engine operation: Not able to bind
to the source (Exception from HRESULT: 0x8004000A (OLE_E_CANT_BINDTOSOURCE)

Cause:
The Regmon log shows we are looking for VBExpress on a 64bit machine:

vbu.exe:2344 OpenKey HKLM\SOFTWARE\Wow6432Node\Microsoft\VBExpress\8.0 NOT FOUND
vbu.exe:2344 OpenKey HKLM\SOFTWARE\Wow6432Node\Microsoft\VBExpress\8.0\VBUpgrade\Sou
rce Language Drivers NOT FOUND

The following key had been erroneously added to the registry during the
installation:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node

and contained one entry for SQL Server. This key should only be present on a 64bit
machine. If this key exists on a 32bit machine, VBU.exe wrongly searches the node
for the components and fails even though the correct entries exist elsewhere in the registry.

Export and delete the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node key.

If you still have any concern, please feel free to post here.
