error in installing DB2 express-c 9.5 on vista

W0w i spent like 5 hours for the installation of DB2 on vista.
i hope nobody is as stupid as me but anyway i write this for people who forgot simple things if you simply download IBM DB2 Express-C on windows vista before installation of db2instance you get this error:

"DB29501E DB2 has detected an inconsistent environment please investigate the following :"DB2INSTANCE:-2029059916"

and even you cant run the db2 command line tools or others which all they retrieve the same error.
If you search through internet you will see this error has so many reasons so but happily in this case answer is easy: you should run the file as administrator by right click on the setup file and that's it now everything is fine.



By the way somebody in the comments asked that she cant see the run as administrator. I am not quite sure about that but i think your vista is not ultimate or business version and you have to change your vista version in order to do programming stuff.
