I just tested this also on a brand new Windows 10 1909/64-bit system.
Just took it out of the box today.
Octave installed without error (except for a note about missing Java).
On launch, I get the following errors:
"Could not copy help collection to temporary file. Search capabilities
may be affected. Cannot load sqlite database driver."
Clicking OK brings up another error:
"Could not setup the data required for the documentation viewer. Only
help texts in the Command Window will be available."
Basic functionality seemed to be there and I could define a couple
arrays and do a "Hello, World" test. Unfortunately, it sort of
degenerated from this point (not Octave's fault though). I tried
installing Python from the Windows store but it failed with and error.
"Code: 0x80070005" was all it said.
is the following file located on your PC, or is it missing:
(assuming you installed to C:\Octave)
I get the same errors on my pc that is missing the above file. That file is missing on mine because currently the libsqlite3-0.dll is being misidentified as a malware/trogan file by a number of antivirus software, and my McAfee deleted it. I'd be surprised that your security software would delete or quarantine the file without a notice, though. Anyway, see:
and recent discussions:
while we are trying to get companies to whitelist the program, it's a manual request process we have little to no control over. In my case reverting back to v5.1.0 worked had no problem. Actually, the problem is with v 5.2.0_1. 5.2.0 gives me no problem.
But you get the same issue with 5.1.0?
