I'm noticing the same issue using the Windows Store app. But it's not the entire keyboard that doesn't work, only alphanumeric keys. I can still tab around to different fields and use the F keys. The on-screen keyboard in Windows will work fine.
I'll let you know if I find anything.
You may also need to update the Horizon View Agent on the VM you are using, if you are trying to RDP to your desktop from the VM. We had an issue with the 6.2 agent doing this.
And I also saw this reply from someone else:
"says, this all started when we tried to install the SafeNet OTP client on our machine. From previous work experience I know that SafeNet has controls in their token software that will lock down USB traffic to help mitigate the risk of keyloggers for their USB based tokens.
Removed the SafeNet client, and, eureka! She's back to typing again. Now I need to figure out how to get the 2 to play nice..."
