Thanks Odin, i was having the same problem but your fix worked for me.
In short:- create the key below
HKEY_LOCAL_MACHINE\SOFTWARE\iTALC Solutions\iTALC\paths
Then:- create string/s
globalconfig - C:\Program Files\iTALC\globalconfig.xml
personalconfig - C:\Program Files\iTALC\personalconfig.xml (we use mandatory profiles so the personal config wouldn't save, we open the iTalc software and switch on autoview, this setting seems to be held in the personal config).
We have allowed lecturing staff modify access to the iTALC folder in C:\Program Files\ so that they can make any changes after the initial setup.
