Installing programs on VISTA

Hello folks, I trying to install non-microsoft programs on my Vista
Business. Some of them are ok, but with TexNic, Notepad++, OpenOffice,
Thunderbird I am having problems.

Which problems?

Cannot copy EXE or DLL files into the target installation path:
c:\Program Files\XXXX

Could not write value for the key \Software\Classes\XXX

Could not write DLL files in the c:\windows\system32 path

Could not execute 7-zip

All the installation programs I am running with the "Run as
Administrator" option. All are with the compatibility mode
"Windows XP" and the privileges for administrators.

So, I cannot install these programs. Please I had a lot of
work delayed beacuse that, Could you VISTA gurus help me?
Is there some of you using MSN Messegner to help me?

Best regards,

Marco

Unfortunately not all programs are Vista compatible. You should contact the
distributors or manufacturers of the software to see what their Vista plans
are.
