So there are probably one of two things that could have happened:
You upgraded to TCS 1.3 and got a new serial number. However the serial number is NOT for TCS 1.3 BUT instead it’s for Acrobat 9.0 Pro Extended only. The intention here is that you would only have to upgrade the Acrobat portion of the installation for TCS.  If you still have the TCS 1.0 media you can install that first without Acrobat and then install Acrobat 9.0 Pro Extended.
You upgraded to TCS 1.3 and got the wrong media. Unlikely but nothing is impossible.
Not sure of course but give it a try and let the forum know.
Also could you send an email to me at ocatave [at] yahoo.com.
Same here. installation issue. please help
You give no information about what the installation issue is so no one on the forum can help. You haven't even told us what version of RoboHelp you are trying to install.
Installation support from Adobe is free so you can get direct support from Adobe rather than user to user support here on the forum.
