How to open a slide of Huawei protected?

Dear friends,

I've downloaded some slides of Huawei, but I can't open it because "Certificate Error"

I attach my file here. Someone can help me how to open them.

Thanks you verymuch

hoangtuna,

I hope that what you are looking for.

You can open your document on huawei's laptop that they are connected to huawei server, I dont think that their is a way to bypass "Rights Management Service".
