Hi
I'm getting this error suddenly, not sure why?
I've used this for many years without issue. My dlls are 2013 - version 6.5.2.4 Standard edition.

Appreciate any help.

Error in IIS:

Code: Select all

Hello,

Thanks for your inquiry.
If the error occurred suddenly, could you please tell us what you did recently?
Have you ever changed the dll version or added any other Spire products? Also, please check if the framework of the references corresponds to the target framework of the project.
Looking forward to your reply.

Sincerely,
Jane

Hi

Thanks for the response, we didn't do anything that I know of. There were some MS OS updates to do with C++ and something else.

How do I check this: please check if the framework of the references corresponds to the target framework of the project.

Thanks!

Hello,

Thanks for your response.
You could check it from the "Target Framework" under the "Property" of your project, for example, if it is .Net 4.0, the framework you referenced should be the same or lower than the .Net4.0.
If the issue still troubles you, please send a sample project to us(support@e-iceblue.com). Then we will look into it and provide a solution accordingly.

Sincerely,
Jane
