I have customers who state they were using CUIC with Chrome and suddenly are unable. I have never been able to run CUIC on Chrome.
Is it compatible or even supported on Chrome?
No. Chrome is not supported with CUIC 9.1
Firefox and IE are.
See below URL for details on versions.
I don't know if it is in Cisco road-map to include Chrome, but as you can see UCCE 11 also only supports the IE and Firefox browsers:
When you say you aren't able to run in Chrome, what is the error?
Chrome is not Supported with Release 11.0 or prior releases. What that means is that the product has not been tested in Chrome Browser. There will be no error but the UI element may/may not work and this will not be supported by TAC.
Chrome is planned to be supported POST Release 11.0
