Pocketbook Annotations Viewer and Tools (AVATeR), need testing

Decided to make an interactive annotation viewer/exporter... testers are welcome.
It can display annotations for recent (firmware 6.x) PocketBook e-readers. There's also some tools from pocketbooktools, but the features are pretty basic, and likely won't be used extensively.

If you can find a use for the program, you're welcome. I tend to highlight *a lot*, and wanted to work with C++/Qt, so that was my angle. The program's been tinkered with for a while now, so most bugs should be gone. All in all a first release seemed OK now.

Requirements
- Pocketbooks, likely only firmware 6.x.
- Windows 8+ 64-bit. Windows 7 might work.
A working Linux version exists, save one minor issue.

Privacy
On first start, the program will ask if it can check for updates. If denied, it shouldn't connect afterwards.

Download
Downloads are available below (basic HTML page, no ads, no JS).

SHA-1 hash for 0.9.5 (Intel/AMD 64-bit) .7z archive (9MB) = 816be8643b08bcd3856bfe4873ec443b30a49496

To install
Unzip the .7z archive, and run either .bat file to start the .exe. Portable mode stores everything in the app dir.
There were prettier .lnk shortcuts, but VBA32 flagged one as malware. For relative directories those shortcuts were a hassle anyway ;)

Beware that pinning portable mode to the taskbar, links to the .exe without it's -p argument (required to make it run as portable), so portable is best run using the icon.

Any comments or requests are welcome. :)
