I was not too happy with my reply- so here's another one. SKW2 might work in 32bit but it is rejected by 64bit.
The SDB files in 2 can be transferred to Sidekick98 userdata unchanged and then choose 'open' then 'SDB file' not the SKCard option. However if you rename your suffix SDB to suffix SKCard the SKCard will open. I think the SKCard is the default.
As regards Notes/Memos SKW2 has the suffixes FDR HDR SKN. Transfer these to Sidekick98 userdata and open FDR. This works. I thought I could also rename SKN suffix as SKWrite but this did not work (Blank sheet).
Anyway, as you want to use 2, the same userdata files can be opened in Sidekick98 64bit, these being all SDBs which covers cards, and to cover Notes it needs the latest NUMBERS files with FDR HDR SKN suffixes.
There's info in the FAQ on how to download the free Sidekick98.
