Comparison.Compare process Continues without error. Errors number 1 writes in (ICompareResult)compareResult. I think the error is caused by the license or products. The same process is working properly when I do on a single page. The second file given for comparison in the complex project returns as a result.
the used products:
GroupDocs.Viewer => 126.96.36.199
GroupDocs.Comparison => 188.8.131.52
