Thanks Squidly Man. That KB did helps me, though only halfway.
After days of troubleshooting I managed to get Project 2010 to recognize natively installed Outlook 2010 and attach file successfully.
I did the Project 2010 capture on a clean win7. There's no need to do a capture on top of Office 2010 installation. Here's what I did.
Do a capture on Project 2010 full installation. I did not launch the application. Simply stop the osppsvc, then do a post-scan.
In package.ini, just uncomment VirtualizeExternalOutOfProcessCOM=0
Set the following to MERGED, as per KB
%APPDATA%\MICROSOFT\AddIns\
%APPDATA%\MICROSOFT\Office\
%APPDATA%\MICROSOFT\Outlook\
%LOCAL APPDATA%\MICROSOFT\Outlook\
%LOCAL APPDATA%\MICROSOFT\FORMS\
%TEMP%\
Set the following folder and subfolders to WRITECOPY
%Program Files Common%%ProgramFilesDir%
Content of my HKCU
isolation_writecopy HKEY_CURRENT_USER\Environment
Value=ALLUSERSPROFILE
REG_SZ~%Common AppData%
isolation_merged HKEY_CURRENT_USER\Identities
isolation_writecopy HKEY_CURRENT_USER\Software\Microsoft\Office
isolation_merged HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Security
isolation_merged HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem
and on HKLM, added the registry given by VMWare Support (same as previous post) and also add
isolation_full HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Windows Search\Preferences
Value=PreventIndexingOutlook
REG_DWORD=#01#00#00#00
isolation_merged HKEY_LOCAL_MACHINE\Software\Clients
isolation_merged HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\00004109A10090400000000000F01FEC
isolation_merged HKEY_LOCAL_MACHINE\Software\Classes\Installer\Components\0470D1FF722D1D114A0B000680FA28E0
isolation_writecopy HKEY_LOCAL_MACHINE\Software\Microsoft\Office\14.0\User Settings\Outlook_Intl
Value=Count
REG_DWORD=#01#00#00#00
Value=Order
REG_DWORD=#01#00#00#00
then change isolation_full to isolation writecopy on HKEY_LOCAL_MACHINE\Software\Microsoft\Office\14.0\User Settings and all its subkey.
