IntegraXor installer is digitally signed before publishing to ensure file integrity. This can be used to check if a file has been tempered or it was not fully downloaded. Below are the file properties window for checking the digital signatures.

"Digital Signatures" can be seen for successful download

"Digital Signatures" tab is missing for incomplete download

Incomplete installer prompts with error: "Error attempting to read from the source install database:"

Another possible error may pop up with message:"An error occur during the installation of assembly...". It should be due to corruption in Windows registry, which may be caused by an unsuccessful install of prior Windows Updates or custom MSI package. This can be confirmed by having similar error while attempt to install another MSI based installer. For instance, 7z compressor. This issue can be resolved by performing a repair install of Windows to repair any corruption in registry and/or Windows system file, then try to install IntegraXor again.
