How to install web service client application in windows server

This post based on my experience when try to install my web service client application created using delphi. I have no idea, why i was get error when fetching data from web service. The problem is setting of data execution prevention that must be enabled in windows server. The following is the steps to enable data execution prevention :

1. Click Start, click Control Panel, and then double-click System.
2. Click the Advanced tab. Then, under Performance, click Settings.
3. Click the Data Execution Prevention tab.
4. Click Turn on DEP for essential Windows programs and services only to select the OptIn policy.
5. Click Turn on DEP for all programs and services except those I select to select the OptOut policy.
6. If you selected the OptOut policy, click Add and add the applications that you do not want to use DEP with.
