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.

i just create a registry modifier like this, go to start/execute and type notepad then press ENTER in the notepad copy this

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\visualstudio\8.0\VBUpgrade]
"HelpLink"="ms-help://MS.VSCC.v80/MS.MSDNQTR.80.en/commoner/redir/redirect.htm?keyword="

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\visualstudio\8.0\VBUpgrade\Source Language Drivers]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\visualstudio\8.0\VBUpgrade\Source Language Drivers\Visual Basic]
@="Visual Basic 6.0"
"FileLocation"="VBSLD"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\visualstudio\8.0\VBUpgrade\Target Language Drivers]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\visualstudio\8.0\VBUpgrade\Target Language Drivers\VB7]
@="Visual Basic 7"
"FileLocation"="vb7tld"

then go to save as. select type "all files" and enter the name that you want and with this extension ".reg". after saved you must execute and select yes to de messagebox and that´s all, enjoy i hope you can update your projects. Bye
