I have written another custom module using vs2008 framework 2.0.  I use 4.7.0 for dev site to test the module and the module compiles and runs without a problem.  I am trying to install (create) the module on a converted(upgraded) 4.5.1.  After install I consistently get the below error which is little help.  I have reference to dotnetnuke.dll in project that is set (default) to copy local.  I have a reference to microsoft.reportviewer.viewer that is set to copy local false.  Both dnn dev and test sites are on dev box and run other modules without issue.  Note that upgraded 4.5.1 site does not include the website directory as it was upgrade.  The file structure of the 4.7.0 site does.  I have tried many things in the last 24hrs.  Any assistance appreciated.

Removed reference to 4.7.0 dotnetnuke.dll.  Added 4.5.1 dotnetnuke.dll to new sub directory and created reference.  Set copy local to false.  Rebuild.  Placed new module dlls in the test 4.5.1 site.  Tried to open page with module.   Site times out/Module page never opens..

So, are you saying that it is a different issue now that you're compiling against 4.5.1?  You're seeing a time-out instead of the error message?  Are you no longer receiving any error messages?
