XP PRO SP2, VB.NET 2005Program runs fine from development windows (XP Pro SP2) and a brand new XP PRO machine but on a target PC fails with clr20r3 invalidoperationexception NET 2.0 Error.How do you find out what is wrong?When installed on a brand new XP the MSI setup downloaded and installed DotNetFix3.5Setup.exe but on the target is says a NET 2.0 error which seems strange.The program uses Appl Framework and a MsgBox was put in as the first instruction which never executed so it must be something is missing.You would think that MS would put out better error msgs so that you you figure out what is wrong.So how do I trouble shoot this and find out what is missing or incorrect?ThanksHELP!!!!Jack / QuickBooks Programming
