Title: Unable to connect (error 99/RSA Key error)
Post by: BruceFeuillette on September 06, 2014, 08:33:04 AM

Hello !
I'm running TV 9.0.31064 on Windows 7 x86. Everything was fine until some weeks.
Tv refuses to connect... Even on the 12345 test server. :-\
Here's the log

It seems that there's an error with the RSA key... Do anybody know how to solve it ?

Thanks !

Problem solved.
I don't know how and when. It works like a charm tonight.
My ID has changed, it's the only visible thing.

ID should be specific to hardware, and shouldn't change.

Was this restored from another computer, or is it a virtual machine, or perhaps accessed remotely via Remote Desktop. These are the things that would normally cause an ID change for TV. (Remote desktop will normally have 2 IDs, one for the concole, and another for a client session. Restored or cloned VMs will often have the original ID that needs to be reset when on new hardware)

TV staff send me a registry file today to change the ID. But it wasn't usefull after yesterday change.
I don't know why the ID changed. Nothing has been modified on my computer, neither accesses from outside.
It was just different at boot.

Just realised too that a recent Windows security update plays with the file system encryption, and that many users are having trouble install any MSI since the update.

If the problem persists, try removing this update from your computer

The error you received is VERY similar to the errors received when trying (and failing) to install an MSI on an affected machine.
