Automation Error

I have spent countless hours working on an app to give to my friends and family as a christmas present. It works great on my machine.

When I install it on other machines I often get an automation error.

I thought I might not have packaged all the dll's needed to run the app so I went back and looked at the references and the components that were checked off for my project and made sure I included all of them in my install program.

It still gives me problems.

At the point the error occurs I am simply hiding one frame and showing another.

Any Ideas?

Does your family have the same version of the program you are automating (ie you are automating say, Word 2000, but they either don't have 2000, or much less Word).

That is what is strange. I am not trying to automate another app. I make calls to the api to play videos and sounds at various points in the program but I do not make a call to any outside programs.

Can't help with video, but have you written code to ensure that there is a sound card, and that nothing is playing at the time you try to play?

I don't think it is a sound problem or a video problem. Thoses elements work fine up until the time I simply try to hide a frame and show another.

I am using timers at this point. I enable and disable them, set their intervals and all that stuff but i have never had problems with timers before. This is all just a bunch a basic stuff.

Whats on the form you are attempting to show? Can the form be shown in any other instance? Maybe you late binded a control (leaving it out of the references and set up) on the form so when it goes to show it something can't be displayed right. Does the program access any kind of database?
