Today I couldn’t install some tool on Windows 2003 SE despite being assigned to the Admisnitrators group. Whenever I tried I get the following message:
Windows cannot access the specified device, path, or file. You may not have the appropraiate permissions to access the item.
If you face such problem, first of all check what permissions you have. To do that, right click on My Computer and choose Manage; then System Tools\Local Users and Groups\Groups; double click Administrators on the right part of the window and check if you are on the list of users with that persmissions.
As I said, I was the Admisnitrator of that machine so that was really strange. So I righ clicked the exe file I needed to run and chose Properties. In the Security tab I found out I have the appropriate rights on that file. I went to General tab of that window; at the bottom, in Security section there was the infromation:
This file came from another computer and might be blocked to help protect this computer.
That was it! You just need to click Unblock button which is next to the above information.
FYI: The whole security section is only visible for ‘unsecure’ files. Once you enable a file’s execution and click OK, you will no longer see it.
