It won't run. What have I done wrong? I tried to run it in my application, with no luck, so next I tried to run it in its own directory. It starts up and gets as far as Welcome to YAFU (which tells me I've got the right executable), then it exits with no messages at all. I would expect something from my last attempt, as I'm not directing the log or the output to files.
Here's what shows on my Command Prompt window, with subsequent attempts passing fewer parameters to the program: Code:

I don't know... hmm. Do you have session.log open somewhere? If so close it... maybe that would happen if session.log exists but isn't writable. I don't know that's my best guess so far.

So I thought I'd download it again, but this time instead of just downloading the executable, I downloaded the whole zip file, and set it up in its own directory among the versions. Again no luck. When I put the version 2.01 executable into the 2.0 directory, I didn't overwrite the 2.0 version. So I've now renamed the files back again and run the 2.0 exe. I factored 26^6519^65 successfully (no point on doing really big numbers just for testing). I noticed that the version 2.0 executable is 2,320,384 bytes, whereas 2.01 is 2,087,424 bytes. Is that size difference reasonable? Would you expect the size of the executable to decrease?

I rebuilt everything and reuploaded yafux64.exe. Everything has worked for me on three different intel windows machines... let me know what you find.
edit, nevermind, I see you posted those details already. Last fiddled with by bsquared on 20210506 at 13:02

First, the good news: it no longer crashes.
Second, the good news: the of parameter works. Third: the version number appears in the session.log file. Quote:
And finally, the good news: I am happy with this. Thank you for your help. Last fiddled with by BudgieJane on 20210506 at 14:20
