Hi,

Thanks for your posting and using our Spire.Office component.
If you use Spire.Doc and Spire.Xls in same project, please add the dlls(Spire.Doc.dll, Spire.Pdf.dll, Spire.Xls.dll, Spire.Common.dll and Spire.License.dll) into your projects, also please ensure target framework of your project corresponds to .NET version of dlls.

Hello Amy,

I'm using the NuGet package "Spire.Office". This automatically adds the dll's mentioned.

Hi,

Did target framework of your project correspond to .NET version of dlls?
for example, if the target framework of your project is .NET Framework 4.0, please use .NET version of dlls is .NET4.0

Hello Amy,

Normally when adding a NuGet package, NuGet installs the proper dll versions. Unless the NuGet package was badly formed. I'll look at this into detail later on to find out if this is the case, and post back here.

Kind regards.

When installing the Spire.Office NuGet package, the dll's are for .Net 2, while my projects are 4.5.2.

Hi,

Thanks for reply.
Low version .Net(example, 2.0, 3.0, 4.0) dlls are able to be used in project for .NET4.5.2. The version of Spire.License.dll in error information you got is spire.office_2.13 for .NET4.0, please ensure all dlls .NET version are same.

Hello Amy,

If i install the Spire.Office NuGt package, all spire dll's are runtime version v2.0.50717. The Spire.License version (not runtime version) is 1.3.5.20, while the version requested in the error is 1.3.5.40.

If i install the Spire.Doc NuGet package, Spire.Doc.dll and Spire.License.dll are runtime version 4.0.30319 , and the version of Spire.License is 1.3.5.40.

Kind regards

Hello Again,

Having found out there was indeed a mismatch between versions of the Spire.license dll, i figured i'd temporarely sove the issue using binding redirects. Turns out there were already binding redirects added. Probably by installing the NuGet.Office package while the NuGet.Doc package was still installed. Just deleting the binding redirect entries solved the issues.

Sorry for lost time and thanks for pointing me in the right direction.

Kind regards.
