Hello,

windows 7 has more strict rules for users and administrators.
The problem may reside on that. Or simply due to an internet access 
problem (firewall?).

It is important to say that not all modules are available, not all 
manuals are available.
This project is something we bring on depending on how many request we 
have for this or that functionality.
We will try our best to improve the availability of documents.

Also we accept the comment to have an easier installation procedure.
We will modify it with a default installation of all modules as soon the 
SEISMOWIN front-end run for the first time.

best regards
Mauro
