Error while installing Juila packages on windows

General Usage
1

I am installing julia packages on my windows machine and i am getting errros that go like this →

*.dll is either not designed to run on windows or contains an error. Try installing again using original installation media or contact system admin or software vendor for support. Error status 0xc0e90002.

I got this error earlier as well when i was trying to install older version of julia by an exe installer.
Any idea on what to do??

A few questions:

  • what is the output of
julia> versioninfo()
  • which package(s) do you try to install
  • what is the output of
julia> using Pkg; Pkg.status()

And if you share the output you get, please enclose any messages in triple backslashes, like ```

All of this was a fresh install on the machine. All packages were installed together via one command and were installed successfully. Errors started popping up after installation at the time of precompilation.

Here is the ss of one of the popups:

For debugging:

Can you remove the DifferentialEquations package and check if it then works:

using Pkg
Pkg.rm("DifferentialEquations")

This package is very large and likely contains many solvers you do not need.

But first, check if this helps. If yes, we can figure out how to install the solvers you need.
