Adobe DC - unable do Digitally Sign by PCoIP protocol

[marekl38079151]

Hi,

I Can't make digitally sign in pdf document. When I press "Sign" button (#1 on pic below) nothing happend. When I click the "View Certificate Details" (#2 on pic below) i see all certificate details. All necessary devices are plug in. It looks that there is no certificte, but I can make a sign using different Application.

I will add that this is virtual computer 64bit and when I connect by RDP protocol - it works. The problem is with PCoIP.

Any idea that this could works in adobe?

Are there any errors logged?

In Adobe Xi that was intalled earlier on this computer when I try to sign, get an error as below that mean "Object is exist".
