Mixed ICA Clients in FR2 environment?

[EGR]

Hi,

Farm: 3x W2k Server SP2, MF XPe FR2, NFuse 1.51

On some (new) clients we have got the problem that they cannot use NFuse. When users click on the icon on the website nothing happens, no error message nothing.
They use an older webclient (6.30).

When I install the Webclient from the ICA Client 8.0 packager it semmes to work.
Now my question: Can there occur any problems when using different ICA clients on the network? So some users would have ICA Client 6.30 others 8.0.
People connect to the farm from all over the world so I can't just update all.

Any issues with PN 8.0 and MF XPe FR2?

Thank You
