Appian lists version 7.2 requirements as Windows 7, 64-bit, and minimum of 4GB o

I run locally on a XP Pro, with 4gb , but CPU never peaked out. I have MS office word, outlook opened and visual studio also opened. and many IE. I guess even with less than 4gb of RAM you can get it working. Appian 7.0 is what i have. 2.9GHz Dual Core 3.37GM Ram.

I have two 7.2 instances running successfully; however, they are both on 64-bit OS systems with at least 4GB RAM. I prefer 64-bit over 32-bit. The new features in v7.2 for UX in regards to Report/Records would benefit from a faster response.
* For others wondering, the environments are Win8(8GB/64-bit) and WinServerDC2007(4GB/64-bit).

Even if you provide 4GB of RAM to a 32 bit windows OS, it is commonly observed to use only 3GB and after this limit, it starts to page. I would strongly recommend using a 64 bit OS rather than a 32 bit OS.
