I purchased this to use with my 5.0 Solo Practice. I had purchased other Therascribe software with no problems. In this case I opened the CD and attempted to install it. I received a message that it was too old and could not be installed. As a result, it can't be returned because it was opened, and it can't be used. So after waiting months for it to finally be sent to me, I have thrown away my money. Be cautious if you have current therascribe software. I have attempted but have been unable to have the information updated for use.
