Recently I got a requirement to install PI 2009 on one of my client. What I figured is the sequence of installation is very important
Here are the steps to follow:
1. Install AX2009 RTM (SYS layer)
2. Install SP1 (SYP layer)
3. Install GLS layer if needed
4. Install Process Industries 5.1.3.1 (BUS layer (compatible with existing GLS))
5. Install RU7 (SYP (+ GLP layer))
6. Install PI BUP layer (specific to localization)
7. Open AX client and run Installation Checklist
BUP layers Installation file Download link is here
Hope this will save Some on time 🙂
