Hello.

Hello,

Thanks for your inquiry.
I did an initial test in a similar environment, but did not reproduce your issue. This is my test project, please run it on your side, and then tell us your test result.

Besides, our Spire.PDF provides a new plugin method to convert HTML to PDF, and its performance is better than the method you use. You can give it a try.

Sincerely,

Hello.

Solved!

Here is the solution:

If you have Office installed in your development computer you have to search the file Microsoft.mshtml.dll

If you don't have Office installed in your computer... i don't know how to obtain this dll. (E-iceblue, can you help?)

Spire.PDF need this DLL to run and normally in test or production servers Office is not installed.

Once you have this dll yo have to copy in your server in bin directory.

Best regards from Barcelona!

Hello Barcelona,

Thanks for your feedback.

I created a project with Visual Studio 2019 on a server without Microsoft Office installed, but after building the project, I found that the Microsoft.mshtml.dll appeared in the bin folder. Then I tried to delete this dll and then rebuild the project, it appeared again. This file should be associated with Visual Studio but not Office. You can verify this by opening your project with Visual Studio 2019 and rebuilding it.
