Spire.Presentation.DefaultTextRangeProperties' exception

[p.passarella@pipegrep.it]

Hi,
after I referenced on my project the free version of SpireOffice 2.15,
the project returns the following exception:
L'inizializzatore di tipo di 'Spire.Presentation.DefaultTextRangeProperties' ha generato un'eccezione.

In my web.config ,SpireOffice.2.15 has automaticaly written:

<dependentAssembly>
<assemblyIdentity name="Spire.License" publicKeyToken="b1144360237c8b3f" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-1.3.2.40" newVersion="1.3.2.40" />
</dependentAssembly>

<bindingRedirect oldVersion="0.0.0.0-3.1.37.58040" newVersion="3.1.37.58040" />
</dependentAssembly>

Which is the problem?
Thanks a lot,
Paola.

Hello Paola,

Thanks for your post.
Your previous information indicates that the issue exists in free version but does not exist in paid version. I am regret to tell you that we have no plan to maintain the free version at present. So please upgrade to the paid version (at present the latest one on our website is Spire.Office Platinum (Dll Only) Version: 3.4.2). And our sales team has sent a 1-month free license to you. Please apply the license (How to Apply the License by license key) to remove the evaluation message.
Just feel free to contact us if you need further assistance.

Sincerely,
Lisa
