Framework 3.5 get uninstalled after cold reboot in mk500



I have developed an application for mk500 device having windows CE 5.0 and frame work 3.5.


When I deploy the code it first inistall the framework "Deploying 'c:\Program Files\Microsoft.NET\SDK\CompactFramework\v3.5\windowsce\'". Copy all the required file and every thing works fine.


When I go to control panel and see remove programs I am able to entries for framework.

But when I do cold reboot then installation of frame work goes away and application start throwing error like component is missing.


I have manually installed the frame work but after cold rebooting the device framework get uninstalled. Am I missing some thing ?


Why it get uninstalled every time? Is there any way so that after cold reboot framework should be installed.
