I'm getting a weird error whiles signing my software. I'm using inno setup 4.5.2.

Running Sign Tool command: signtool.exe sign /a /f cert.pfx /v /t "http://timestamp.verisign.com/scripts/timstamp.dll" /p pwd /d "Setup Label" "out\uninst.e32.tmp"
SignTool Error: An unexpected internal error has occurred.
Error information: "Error: Store IsDiskFile() failed." (-2147024893/0x80070003)
Error in W:\path\installer.iss: Sign Tool failed with exit code 0x1.
Compile aborted.

Command line seems pretty ok, it even work outside the inno setup compile. While setting the SignedUninstaller=no get me farther, it still make this error while trying to sign the output setup file.

Now i've looked pretty much everywhere for that error code (0x80070003) and/or the message "Store IsDiskFile() failed". I have also tried with multiple version of signtool.

I figured out the problem, the path to the certificate must be relative to the installer output path, not the current working folder. In this case, it would be "..\cert.pfx".

I had the same problem. My problem was I have used " in the signTool command, while I needed to use $q instead. Surprisingly it was successfully signed the executable but it failed to sign the result setup.exe file.

My problem was having the .pfx file on a network drive (G:). Moving it to a lokal drive (C:) solved the problem.
