Right I'ver finally finished my first app with a deployment package (using Visual Studio.Net 2003 and Crystal Reports) and it works fine as long as the app is installed on individual clients C drives.

I have taken a copy of the bin folder and copied it to a network drive and created a shortcut to the .exe

The application opens fine from the newtork but when I try to execute any code i get the following error message

************** Exception Text **************

Can anyone help me get round this issue as the app really needs to run on the network.

All clients will have the .Net framework installed.

Thanks
