Originally posted by Sophil40 I've got all administrative's right on my computer and tried many times to install this software with my account. There are no issues during installation. The problem is when I try to launch it. A window opens and closes immediately. I wrote to Pentax to have some advise about this issue. But on their side it seems like this software is a gift and you can't complain on it. I never received any answer so I'm trying to solve this by myself. It's probably something depending of the hardware or of the software I've got on my computer. So I understand the no answer from Pentax because it's probably too much difficult to solve something depending of all kind of computers configure you can find on their client's side.
Then the installation shouldn't be the probleme as it was for me in the beginning.
If you have enough fysical RAM the other issue I can think of is antivirus and firewall software. You could try to disable both for a quick test.
