Error 2869 in Vista during install of Dev Env 1.3

Question

If you try to install the version 1.3 of the Developer Environment on Vista, there is a change you may get an error 2869 during install.
This has to do with the UAC in Vista and requires some special handling when creating the installer package.
I don't know if this will reach the developers at SAP, but here is some references to how to handle the problem:

For users, again depending on your UAC (User Access Control) settings, this MAY help you.
Create a .bat file with this content:
@ECHO OFF
ECHO.
ECHO Installing on Vista
ECHO.
ECHO Be sure you are running this as Administrator!
ECHO.
PAUSE
ECHO.
ECHO.
CD C: ... path to ... B1DESetup_2005SP01_1.3_VS2005
msiexec /i "B1DESetup.msi"
ECHO DONE
ECHO.
ECHO If this didn't work you may have to disable UAC in Vista while installing
PAUSE
Save it.
Right click the .bat file and select "Run as Administrator"
If this doesn't help you may need to disable UAC while installing.
