Installation

Windows

Error: nw_elf.dll not found

When executing Icestudio I get this error message (In spanish)

  • Reported by: Demócrito

  • Solution: Just reinstall icestudio again and the problem should be gone (Solution provided by Democrito)

Toolchain installation stalled at 30%

When installing the toolchain from icestudio, the installation bar freezes at 30%. I did not have problems with Icestudio in earlier versions

The problem was the Antivirus preventing icetudio from executing external programs for downloading the toolchains

Steps to solve the problem:

  • Run "icestudio.exe" (nothing weird detected).
  • Select install toolchain: at 10% the AVAST was activated automatically (automatic new advise in my toolbar) about "POSIBLE SOFTWARE MALICIOSO SE ESTÁ EJECUTANDO".
  • AVAST gave me 2 options: remove the app (as a security measure) or trust it and add the "icestudio.exe" to the exclusion list. Select "include in the exclusion list", icestudio run and the toolchain install continued and finished satisfactorily.

The problem was not detected because the first time Icestudio was executed it did not show the previous messages from the Antivirus. After rebooting the computer and installing it again, the warning messages were display

After that, the installation completed successfully:
