NanaZip.Core.Setup.sfx installer shows "Can't load config info"

[kbarnes3]

I built NanaZip.Core.Setup.sfx using the latest version from main. When I produce an .exe with this version, I always get an error "Can't load config info". I produced an .exe by running:

cmd /c copy /b .\NanaZip.Core.Setup.sfx + .\config.txt + .\bootstrap.7z Installer.exe

Where config.txt looks like:

,!@Install@!UTF-8!
Title="My Team Program Installer"
BeginPrompt="This will install My Team Program."
ExecuteFile="powershell.exe"
ExecuteParameters="-ExecutionPolicy Bypass -NoProfile -File bootstrap.ps1"
GUIMode="2"
OverwriteMode="2"
DeleteGifOnComplete="1"
,!@InstallEnd@!

If I instead produce a non-setup SFX by running:

cmd /c copy /b .\NanaZip.Core.Windows.sfx + .\bootstrap.7z Installer.exe

I do get a working executable, although obviously without the setup happening. Is this expected to work?

I realized the config.txt should have ; instead of ; on the first and last line. Even with this change though, I'm getting the same error. Looking at the NanaZip.Core.Setup.sfx produced by VS 2026 in a text editor, I see ";!@install@!UTF-8!" and ";!@InstallEnd@!" rather than the , version that's defined in kStartID and kEndID. I think the compiler might be optimizing this block away by inlining this into the binary instead:

static struct CInstallIDInit
{
  CInstallIDInit()
  {
    kStartID[0] = ';';
    kEndID[0] = ';';
  }
} g_CInstallIDInit;

Would this break the config file detection?

Thanks. I need to do some investigation locally for that in recent days.

I was able to get past this by wrapping the relevant section with a #pragma optimize. This might be more heavy handed than needed though.

#ifdef _MSC_VER
#pragma optimize("", off)
#endif

static char kStartID[] = { ',','!','@','I','n','s','t','a','l','l','@','!','U','T','F','-','8','!', 0 };
static char kEndID[]   = { ',','!','@','I','n','s','t','a','l','l','E','n','d','@','!', 0 };

static struct CInstallIDInit
{
  CInstallIDInit()
  {
    kStartID[0] = ';';
    kEndID[0] = ';';
  }
} g_CInstallIDInit;

#ifdef _MSC_VER
#pragma optimize("", on)
#endif

However, now I get a crash when extracting the 7z file. The .7z file concat'd onto my installer was created with the latest version of NanaZip available in the Windows Store. I'm getting a crash at the end of the ExtractArchive function as CThreadExtracting t and its member ComPtrs are released.

I haven't figured this out yet.

I have got the reason for kStartID and kEndId. I will try to make a fix in recent 24 hours to the main branch.

But the crash issue I need to do some investigate.

I also found the reason why caused the crash.

I have done some fixes. You can test that if you want.

Thanks, I tested the main branch as of 6f8ac860f755fc49f9f0cd25f20191ba481c94d3 and everything seems to be working as expected. My installer program runs consistently now!
