Delphi 7 on Windows Vista

Borland Delphi 7 was released in 2002 and perhaps you may still use this software. If we run it on Windows Vista, an error raised with the following message "Unable to rename C:\Program Files\Borland\Delphi7\Delphi32.$$$ to Delphi32.dro".

I thought that was about security access/permission. With Administrator privilege, I did these:
1. Right click on C:\Program Files\Borland\Delphi7 directory, then click Properties.
2. On General tab, clear the Read-Only attribute then press Apply (all files including subdirectory).
3. On Security tab, Check or give Full Access to Users.
4. Click Apply.

That's all.
