Hello Nicola; I have just bought the software for 777. I had crash everytime I try to launch the soft. I have separated topper from any Firewall or protection. I try to launch the program as admin. I try to erase and relaunch the installation. But the weird things is that I have no clue why it crashes. It writes nothing but "it seemed there is a problem with this software blablabla" but without any technical explanation. I have read on this forum that it could be a problem to have Win7 in french... I have Win 7 in french version. You have send a link to the person but it is not valid anymore. Could you help me years after the creation of this program? Thanks anyway for your work it seemed to be a really good program. Have a nice day Nicola D.
