I am able to run Piano Roll Box Label Maker (PRBLM) on a 64-bit
Windows 10 computer. These are the instructions that I use:

- ROLL LABEL MAKER
- Download the ZIP file.
- Unzip to a directory on your PC.
- RUN prblm.exe
- Copy "newfiles" into "templates" in the installed directory.

Terry Smyth has some additional labels on his web site, see

If you get stuck I can produce labels in Australia for you. 
These are 15 to view self-adhesive 50mm wide x 49mm deep.

I also do self-adhesive tabs -- see my eBay listing:
