cannot deploy controls

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'm building an app that requires a calendar control, and stumbled on CodeJock's ActiveX COM Suite Pro, which has a nice calendar control.  I was able to work the calendar control into my program just fine, but when I went to deploy it to another machine, after installation the app crashed.  No matter how many times I rerun the app (or the installer), it keeps crashing on this other machine.  I've tried creating a simple blank project (both vb.net and c#, .net 2.0 and 4.0) and publishing it, then installing on this problem machine, and it works just fine.  however, when I drop a single calendar control onto the empty form canvas and repeat the process, I have the same problem I did in my real application.  I think these controls have great promise, but if I can't deploy to my client machines, I'll have to keep looking 

another interesting observation that I'm adding after the fact: if I remove the control from the form, but leave the references in the project, the app runs fine and the blank form pops up without crashing.  So the presence of the references to the controls don't seem to be a problem, only having the control on the page.  I've further tested with other Suite Pro controls, and have the same issue.

So, can anyone PLEASE offer me some guidance on what I should do next?  Here's specifics:
development machine
Win 7 x64, Visual Studio 2010 Ultimate

target machine
win xp x86, sp3 running in Virtual PC on the Win 7 box

as mentioned before, I've tried from scratch in both vb.net and c#, with .net versions 2.0 and 4.0.  correct .net frameworks have been properly installed.  when the Suite Pro controls are present, the app won't run.  when they are not present, the app runs just fine.

Thanks!
