I am using Spire.doc Free version. I am using it to convert preexisting Word documents to Pdf files.
On my development machine everything works fine. However, when I install it on a user's machine it crashes when it hits the Spire code.
I install the app via a .NET installation project, which creates a Setup file and an .msi file. It includes all the necessary Spire .dlls - Spire.Doc, Spire.License and Spire.Pdf, and I can see them successfully loaded on the client machine. But the app still crashes.
The error message is a very general one "The application has an error" and closes down. The Spire code is within a Try...Catch, yet the error is not a type that is even caught. No other info. However, I have definitely narrowed down the crash site to the command Dim Doc as New Spire.Doc.Document.
Am I missing something?
Thanks for any assistance.
