Vb.net app works on Vista/7 not on XP

[mbryantuk]

Hi

I am a newbie at creating applications but i have created a vb.net application using the ReportViewer control, tabcontrol and a database driven treeview control. when i build the application it works fine on Vista/7 but not on XP/Server 2003,

I have tried it on a xp machine with .net 3.5 and it still gets the error.

The error is An unhandled exception ('System.InvalidOperationException') occured in Reports.exe [4364].

thanks for your help

Did you create a deploy for the application and deploy it on XP or did you just copy over the exe?

Also something to think about for instance is are you running 64 bit on Vista/W7 and 32 bit on XP?
