Files save in Topaz Studio .cr2 issues

I have a vacation folder and for some reason it was saved in Topaz Studio .cr2 and I can not open any of the images. I didn’t realise until I tried to open in Lightroom, so I tried in Lightroom Studio and it just says error. HELP

Topaz Studio not Lightroom, sorry

Firstly was is your OS? And what do you mean by “saved in Studio 2”?

.cr2 - isn’t that the old Canon RAW format? This may explain why you cannot open … !
