Hi Gunnar,

Error 0001:000-4 means that the installer stub loader was unable to unpack the decompression library into the temporary setup folder. The CreateFileA Windows API returns INVALID_HANDLE_VALUE in your case. It's very well possible that protection software systems "block" your installs (e.g. caused by a false-positive on your images and/or your code-signing certificate). You can try to check this on VirusTotal.com. But it has nothing to do with SetupBuilder. The installer stub loader (and the decompression component) did not change for years.

And please make sure that your code-signing certificate has a "good" reputation. Use "dual" SHA-1/SHA-2 code-signing for maximum backward compatibility and to minimize false-positives.

Hope this helps a bit.

Friedrich
