Thanks for your reply.

I had already done that. The problem is not with file associations. The error
message says the version of NTP is incompatible with Win7 64-bit.
I just discovered the problem. I was running version 6.12/fv. Moments ago, I
updated to v6.2/fv, and the compatibility issue disappeared.
Other strange behavior that is now corrected:
I didn't have the Swiss flag icon on OTL files nor on NotePro.exe itself.
None of my clip libraries were visible on the clipbar nor when I pressed F4 to
bring up the clipbook panel.
When I had double-clicked on any of the CLB library files, I was getting the
same incompatibility error message as was displayed when I had tried to open
an OTL file.
I am mentioning all these problems that are now corrected because others may
one day search the archive and they will see that the upgrade to version 6.2
fixes all these issues.
