One of the problems I had setting this up on another machine of mine was that (at stage 2) PowerStore insists on a MySqul user password.
Quite often default installlations of mySql don't have a password unless you specify it during setup. You therefore have a catch 22 situation in which PowerStore demands that you enter your mySql username password (and won't continue till you do) , and you're shouting at the screen that you don't [/i]need one.
If that is the case, you will have to set an Admin root user password for your mySql installation, in order for PowerStore to carry on with the installation.
Some 'installer' versions of mysql - whether a microsoft .msi installer package, or part of a server 'package' (WAMP, XAMPP etc) can allow the whole setup to go through without you setting a root user password for your mysql database. If you don't remember setting a password during the install, then the chances are that there isn't a password that you can actually enter during the PowerStore install.
If you are using IIS as a testing server, you may or may not have been given the opportunity during install to specify an Administration root mysql password, if you haven't then you need to set it using mysqladmin which you access via the windows command prompt (NOT the mysql command line).
With Wampserver, I belive that the option is there (briefly) during install, but it says that you don't need to specify a mysql password now, you can do it later. You can check if you have set a password by opening the wampserver menu from the taskbar system tray (notification area) and selecting the MySql console from the MySql menu item. With the console (mySql command line client) open and asking for your password, if you just press your 'enter' key and you get the 'Welcome to the MysQl monitor' line (& some stuff about commands) and the mysyl> _ prompt, then you have not set a password. If that is the case, then PowerCMS wont get set up until you set the password.
If you need help doing this then post back.
With Xampp, you don't get the opportunity to set a user password during set-up, you're expected to know about setting it if you want to. However, it is easy to do in XAMPP. Either open your XAMPP homepage (localhost) and clickon 'security', or just open your browser and enter security . In fact, if you have XAMPP, you could just click that link.
