Vista - administrative rights!

Let'start with .......... I am the administrator.......Vista says so!


But when I try to install a program, Windows says "I must have
Administrative rights to install......See Windows help (msi.chm) or MSDN"


How can I tell Vista that I have these rights?

Any suggestions will be appreciated.

thanks

Does this issue relate only one program or all? If there is only one program I rather suspect this program is very old and is non-compatible with UAC -in this case try right click on installator and choose "run as administrator".If you have the same problem with all programs you have very seriously issue...
