Unlike the v.5 that was previously given away, the Photoshop compatible plugins are not included -- I used Universal Extractor to expand the files in the setup program to verify this. That matters because while Photoshop can open files HDR projects saves in an HDR compatible format, a great many image / photo editors cannot. That can hurt a little bit since HDR projects 6 is not a full editing app, and when you can't import the full HDR image you have make do with a version of the HD photo that's been converted to a normal, non-HDR image. You're probably going to save the HDR photo as a regular image file anyway, but the work you do on the full HDR image in your editing app can have an effect on what that converted photo looks like.

HDR projects 6 is much larger than v.5, at ~450MB, since it includes 82 texture files. It also seems to move away from HDR projects earlier focus on [IMHO sometimes garish] photo FX, to become more serious HDR, and functional software. Doing so may have made it harder to use, with more available options. You'll probably want to set the compatibility on high DPI displays: Properties -> Compatibility -> Change high DPI settings -> Override... checked -> System or System enhanced.
Installation follows the standard for Franzis software giveaways... use your established Franzis account email address, sign in, and get the activation info via email. Once you enter those numbers in the setup wrapper the real installation program is unpacked in the User's temp folder -- copy & save that if you want before setup proceeds. I normally install these Franzis apps in a VM [Windows sandbox will work], since like today's giveaway they often include Microsoft C/C++ runtime installations -- I find these usually highly redundant [check the size of the Windows\ WinSxS folder], so just copy the program's folder from the VM, run & activate it. The app will add the files/folders under C:\Users\ that installation would otherwise add.
The market for less expensive point & shoot cameras has pretty much evaporated, while the price of entry level DSLRs has dropped -- you can usually find Canon cameras comparatively cheap, especially remans. As more people have cameras that can take bracketed photos, HDR has grown more popular, and you can find all sorts of info, How-To articles etc. online. The short explanation is that in difficult lighting situations combining the data from 2 or more photos shot at different exposure settings can produce a more balanced photo, without portions being blown out [too bright] or too dark to see anything.
Note: you can certainly use the camera in your cell phone too, though you may have to add an app like Camera FV-5 to enable bracketed shots.
