PowerStore installation problem resolved
I was able to complete the installation.
Here's what happened:
My first installation was flawed as I didn't create the database first. I tried to fix the problem by creating it later.
That didn't work out because the wizard would go directly to administration username and password dialog window 4 of 7, bypassing other installation windows.
The store info, database info and serial number were already in place, but the tables had not been created, so I couldn't complete the installation. A catch 22.
I removed the Configuration folder as suggested, but still couldn't complete installation.
I did an activation reset and was able to complete the installation by getting to window 1 with a new serial number.
Thanks for your help.
