Advanced Photoview 360 problems

Photoview is giving me headaches. It worked as it should up to a few weeks ago, ever since, it opens up and closed right away.

- I have reinstalled bonjour many times over to no avail
- I've reinstalled Solidworks itself a few times without effect.
- I've reset the key registry to try and open it as factory reset, didn't work either.
- I've installed a different virusscanner (Eset to Norton) because I had a feeling that one removed or "quarantined" photoview files.

I have no idea what else I've tried but I feel like I've tried everything I could find online and posted on other questions on this forum.

Anyone who knows what else I could try?

Thanks a lot in advance.
