ICFB ERROR

Hi All,

We are using Citrix MFU 4.
When users try to launch ICFB (Cadence)tool, They get the below error:

Using Cadence version ic5141_isr141
*ERROR* Failed to find either 24-bit TrueColor or 8-bit PseudoColor Visual.
*WARNING* Failed to find either 24-bit TrueColor or 8-pbit PseudoColor Visual.

OS is Solaris 10 9/10 and using CDE.

Please give me suggestions on this.
