Any chance you're using any ActiveX controls or something else where different machines might not have the appropriate setup prior to running your application?

Sent: Monday, January 29, 2007 2:31 PM To: ADVANCED-DOTNET@DISCUSS.DEVELOP.COM Subject: [ADVANCED-DOTNET] System.InvalidOperationException Hello everyone, I have this application that I built using VS2005. It runs OK on my development machine using either the IDE or the exe that VS2005 produces. It, however, does not run on my test machine. As soon as I launch the application on the test machine, I get the Microsoft "<program> has encounted an error and needs to be closed...." error message. The initial error is a System.InvalidOperationException. I put some code in the source that would print out to a text file what methods had work and where it stopped working. It appears that it stops working in the application's first form's InitializeComponent method. In other words, I don't believe it gets inside the method. Anyone seen anything like this and if so, any suggestions on how to solve this problem. BTW - I move the executable and all files to another machine that has VS2005 installed and the program works flawlessly. It just doesn't on the client's machine. What a bugger! Thanks for any help.
