Version 5.4.2 - Older environment, can't copy/paste

[Drdre1978]

Hi everyone,

I have the following issue in an older Horizon environment.

View client: Windows 7

View version: 5.4.2

Issue: after GPO implementation (PCoiP) copy/paste doesn't work.

Even after a restart of the client.

Configure clipboard redirection: Enabled in both directions

Virtual channel settings: 3  Enable all virtual channels other then.

Am I forgetting something. I think this was all in according to documentation.

Hi Drdre1978

Login to the VDI from client and confirm below registry exists inside the VM:

Clipboard redirection is implemented as a virtual channel. If virtual channels are disabled, clipboard redirection does not function.To confirm virtual channel is enabled make sure below reg exists on VDI:

Registry Hive HKEY_LOCAL_MACHINE

Registry Path Software\Policies\Teradici\PCoIP\pcoip_admin

Value Name pcoip.enable_vchan

Value Type REG_DWORD

Value 3

Then to confirm copy/paste function is enabled, make sure below reg exists on agent: 

Registry Hive HKEY_LOCAL_MACHINE

Registry Path Software\Policies\Teradici\PCoIP\pcoip_admin

Value Name pcoip.server_clipboard_state

Value Type REG_DWORD

Value 1

If these reg values are not correctly set on machine even after pushing it through GPO,manually create above reg values on gold image and recompose/push and test again (Sometimes setting it through GPO doesn't work due to default domain policy or other policy conflicts.)

Please mark my reply as correct/helpful if it resolves your issue.

HelloShreyskar ,

Thank you for your reply.

1) I logon to a startup VDI (windows 7, client 5.2) and then start a pool with specific VDI's. (Windows 7, client 5.4.2)

2) Both VDI's have the policy and both VDI's I see the following registry settings.

The only difference I see in what you've posted is pcoip_admin_defaults my side, pcoip_admin (your post).

Must I change it? Or is there a firewall rule necessary?

Kind regards,

Andre

Hi Drdre1978

You need to create pcoip_admin reg hive under Teradici\PCoIP and then create both these REG_DWORD values and test again. Leave pcoip_admin_defaults as it is.

Hey Shreyskar​,

After I read your post I've already implemented this and restarted the VDI:

Stil no copy/paste is possible unfortunately.

Kind regards,

Andre

The user starts a VDI from a VDI pool (jump machine) and in this VDI the user starts another VDI from another pool (application).

I think that is where the problem start. You can copy from local machine to VDI and back. But not from VDI to another VDI, am I right?

If you use the VMware Blast display protocol or the PCoIP display protocol, a Horizon administrator can configure this feature so that copy and paste operations are allowed only from the client system to a remote desktop or published application, or only from a remote desktop or published application to the client system, or both, or neither.

Hi Drdre1978

I suspect you are connecting to nested VDI sessions. Though horizon has few limitations when running nested mode VDIs, clipboard redirection is supported in nested mode.

Features Supported in Nested Mode

You can also check the supported nested scenarios below:

VMware Knowledge Base

Hence clipboard redirection should work in nested environment given you are running one of the supported scenario as per above KB. If copy/paste still doesn't work, make sure VMwareViewClipboard.exe service is running on both the VDIs , if it is not, you might have to reinstall view agent to fix any corruption to this binary.

Hey Shreyskar ,

Many thanks for your support in this case. Yes i'm working in nested environments and these requirements are exactly what i'm looking for

Take care and stay healthy.

Kind regards, Andre
