Extension is not installed

I'm trying to open a file using an extension which can be dropped and used freely in new applications. But opening a particular MFA gives me this:
Please login to see this link.

It's not in blocked extensions, and it loads fine in a blank program. I also removed a mfx file with a similar name just in case the two were conflicting. Even DllMain() isn't executed during the load; there's a first-chance CFileException (once), then subsequent attempts to load don't even throw that one.

I'm at a loss. Surely there'd be a different error message if it existed but couldn't be accessed. I attached the extension if you guys want to test.

Opening a particular MFA? Are you sure it's not corrupt?

Phi · June 12, 2013 at 7:31 AM

Yes, it's not corrupt, none of the 100 auto-backups work either. Just one day, poof, this error.

What I mean is, do new MFAs you save have this problem?

Phi · June 12, 2013 at 10:02 AM

Good catch, but no, they save and load fine.

If new MFAs do not have the problem, but all your backups of that one MFA do have that problem, then you have probably just made a change that causes your extension to be compatible with all previous versions. Do you know what you might have changed to cause that, or at least when?

Also, make sure to clear out any extra duplicates of old versions of the MFX - often times old Unicode or HWA versions remain and MMF2 for some reason has inconsistent priorities for which MFX it loads. This happened to me and was very frustrating.

Nope LB, I have no idea what would cause the problem. I haven't removed any a/c/e, and it should be a complete match to an old version otherwise - at the very least, one of the 100 autobackups would be using a compatible version.

So you rewrote it with another SDK?

Phi · June 13, 2013 at 9:26 AM

No, same SDK consistently.

LB · June 13, 2013 at 4:52 PM

Did the version of your compiler change at all?

Phi · June 13, 2013 at 6:27 PM

No, same compiler, consistently.

LB · June 13, 2013 at 9:42 PM

Can you list everything you changed between the version that loaded the MFA and the version that doesn't? Just summarize, not actual lines of code or anything (e.g. "changed stuff in the resource file")

Phi · June 14, 2013 at 2:52 PM

No, I can't, or else I would have reverted it.
The error looks to be more MMF2's fault though, as according to the error message it can't find it.

LB · June 14, 2013 at 4:05 PM

"Can't find it" is a generic error message, any kind of error could have occurred to generate that error message.

What I don't understand is why that one MFA and all backups have that problem and new MFAs do not - my only explanation is that you changed compatibility somehow.

Phi · June 14, 2013 at 9:59 PM

I concluded that, but a generic and misleading error message isn't going to help me find it. I can't access any of the MFA's data to find out what is going wrong. It's a bit like working out A + B = C, except C is uninformative, and A is unreadable. You're not gonna find out what B is.

I'm having this issue, too, though I don't think I need to take a screenshot, as Phi's screenshot shows the situation just fine.
