Our WPF application works with your InfragisticsWPF4.Documents.Excel.v11.1.dll perfectly when it is installed via ClickOnce (VS 2012).

However, we need to also install the application in a Citrix environment. (Basically a virtual machine that has the application installed for business users).

Click Once installer, in this case, is not useable... since the install must be available for all users.

So I've created an InstallShield installer for use in putting the application on the Citrix environment (which is done by another team... i don't have direct access).

----------------------

In the InstallShield version... when attempting to run the code that creates an Excel Document, we get a cryptic "Fatal error during installation" message from the caught Exception.

I'm guessing we're missing something in the installation? Since we have to manually choose the dlls and files that go into the InstallShield installer, it's virtually impossible to know what else is required for the code to run.

Unfortunately I don't have a "clean" environment (one without Infragistics installed) to test our installer packages on... the client only authenticates their own machines to work on their network, and I don't have an extra on which to debug.

On my machine, the InstallShield version works fine... I'm guessing because of something that is installed. Whatever that is should probably also be installed on  Citrix. Again, the Infragistics DLL (Excel document creator) is in the Local folder, so it isn't that.

Could you suggest what else might need to be installed on that machine? Is there a runtime package we can install for the WPF NetAdvantage stuff?

Thanks,
