In our College, we install Inventor on many computers so the students can use at their own time. There is also an installation in some computer classes(clusters). As a policy of the College, all public computers including the clusters are protected against changes in disk C: where the operating system is, and specifically, many configuration files are stored on a network server and downloaded when a computer is restarted .(this is called roaming profile)
So, the problem is in downloading the configurations of INVENTOR. If the roaming profile holds any specific information belongs to Inventor, there is some unknown problem and some features would not work at all (the icons are not recognized and more important, all the mold design is not working.) A workaround we figured out is to break the sync of the roaming profile with the local computers (only with regards to Inventor). But now there is still no way to make configuration changes to a local computer and keep them after a restart. (the changes are probably written to the registry).
However, now I can not save the configuration changes in any of the class computers. ( our OS disk is protected against permanent changes and will reset itself on any restart\ reboot, unless an administrator does them).
I tried making changes to the configuration both as administrator user and also when giving the local user administrator privileges, but with no successes.
