HP Prime Virtual Calculator Latest version

[retoa]

Thank you very much for the hint !

I have administrative privileges on the school PC's, so I can install, but the solution with the folder copy is much better. Also the students could copy the folder on a USB stick, so they will have the same datas at school and at home.

I have another quastion for you about the connectivity kit.
I installed it at home and it works fine, at school it worked fine last june, now it does not recognise the calculator anymore. I changed port, calculator and cable but the problem remains. The calculator does not appear in the list.

-tried all sequenses, connect first, start CK first, turn calculator off/on, ...
-same behaviour on all the school PC's I tried so long.
-all Windows 7
-on some PC'c new windows patches were installed in the summer on other not, they all behave the same
-I tried as user and as administrator, no difference
-no errors in PC device controls
-I tried with a new calculator and the included CD to be sure the versions are compatible, it does not work

Do you have an idea where the problem could be?

Thank you for the help
