I agree with both Bob and Ola. We have tried not quite yet succeeded in getting DHIS2 installed with Tomcat/Postgres on Windows with a one-click installer, this my caveat about a "supervised" install. There are a lot of things which can happen on users machines and maintenance becomes a huge issue. DHIS is still under intense development, and a lot of things change quickly. Upgrading a single server is a piece of cake. Upgrading dozens or hundreds of off-line machines is a true nightmare and a serious risk and resource drain to any deployment.
I agree with Ola. Totally exclude an on-line server as an option first. If you have already done that, all I can say is, be prepared for a LOT of tech support.
