We have a solution that uses Aspose.Words to create document templates for SharePoint. This solution uses the 9.4.0.0 version of the assembly and has been working fine for some time.
Recently we installed a 3rd party solution that uses the 10.6.0.0 version of Aspose.Words.
Now the method that saves the document template(Aspose.Words.Document.Save) throws an exception: "Invalid save format requested." (called with a MemoryStream and SaveFormat.Docx)
I have tried to set specific version in our solution (Visual Studio 2010, Specific version on the reference), but the error remains. I have seen a similar issue in the forum (), but this does not help with my problem, since both assemblies exist in the global assembly cache.
To make the issue even worse, I am unable to reproduce this error in a console application, but the fact remains: one dll in cache, OK, two dlls in cache, fail.
