Symbol MC9090 RIF - Windows CE 5.0

[=?Utf-8?B?Q2xhdWRl?=]

I made an application in C# .Net Compact Framework 2.0 for a Windows CE 5.0
device (Symbol MC9090 RIF scanner). To install my homemade application on the
device, I used « Deploy solution » menu button from the Visual Studio 2005
IDE. In the project options, I set the destination device to « Windows CE
Device » and the folder of installation is « (Default Folder)\MyCompany ».
When the menu button is clicked, Visual Studio installs :

- .Net Compact Framework 2.0 (in \Windows folder)
- Symbol.Net assemblies (in \Windows folder)
- My application (in the \Program files\MyCompany folder)

Everything is fine. The application works properly, so why am I complaining ?

Here's the problem :
If I don't change the battery frequently, everything is lost !!! I have to
reinstall everything using the « Deploy solution » from the Visual Studio
2005 IDE. That's a pain in the neck since I've got 5 Symbol MC9090 RIF
scanners to take care.

My Question is :
How can I install PERMANENTLY the application on the device ?

P.S. Sorry, but my english is a bit rusty.

Thanks,
Claude
