Dear nwuaku,
Thanks for your inquiry.
Sorry that I am a little confused, Spire.Doc cannot view the document. Did you mean you convert Word document to PDF using Spire.Doc ? And could you please describe you issue in detail using another way ?
Moreover, we first suggest you try to use the latest
Spire.Doc Pack(hot fix) Version:6.0.3 which includes the improvement to check if the issue is solved on your side. If it still exists, please offer us the input file and the code you were using as well as the information of production for testing.
Thanks,
Betsy
