Hi Everyone,

I’m trying to install the trial for pix4d to evaluate to buy. When I download it from the [https://cloud.pix4d.com/download/](https://cloud.pix4d.com/download/) website and install it it gives me the following error.

I have tried multiple times, with the antivirus SW disabled and no change.

Any thoughts?

Oh, I forgot to mention, everything appears to install correctly. I get this error on the first run of the software.
