Apologies if this is the wrong area.

I was directed here from the IJulia Github page (I got it wrong there also)

I am unable install IJulia on Windows 10.

Please let me know if I should continue or this topic should move to a different area.

Welcome to the discourse forum!

Which Julia version do you use?  
What did you try and which error message do you get?

in a Julia console:

Julia 1.8.5

using Pkg  
Pkg.add(“IJulia”)

Very long out put after that, is there a place to post that (ie. not here?)

Do you have a clean environment?  
What is the output of:

```julia
using Pkg
Pkg.status()

```

It’s a fresh install. That was the first package I tried to install.

I just tried it myself, add it worked without any issues. So if it causes issues for you we need to see the error message. If it is long, can you copy it into a .txt file and attach that file to your message?

Also interesting would be the output of:

```julia
versioninfo()

```

and the amount of RAM and free disc space you have…

Well, that is an error that is not so easy to understand. Perhaps someone more experienced could have a look?

I can only guess:

- is sys.dll corrupted?
- a virus scanner deleted a file?
- missing access permissions?

Hmm, virus scanner. Let me disable mine and try again with a fresh install.

I have admin access to this computer but as you can see i’m trying to install in a local profile.

For Julia there is normally NO need to be adminstrator, just try to do everything as normal user…

Ok. virus checker disabled.

Slightly different error this time. Attached.

I’ve tried a few other things.

I read in a forum (can’t recall where now) that deleting the General registry worked for those getting a similar error, but not for me.

I DO have WSL installed and I have IJulia installed in that, and Jupyter notebooks with it work as expected.

It’s only Windows 10 where it’s not working. For me anyway 🙂

Your problem seems to be this issue (found by googling the relevant parts of the error message: `"EXCEPTION_ACCESS_VIOLATION" "fs__chmod"`): [add package crashes with Exception violation when I try to `add` any package · Issue #41642 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/issues/41642)

The only other thing you could try is to use an older Julia version, e.g. 1.8.3 to find out if this bug is specific to 1.8.5.

The problem with Windows is that exactly the same Windows version can have different system .dlls installed…

I believe I have solved the issue.

I use a ramdisk, with only 4gb of space (I can change the size at will).

I changed my env variables for the tmp/temp directory back to a data drive, and the package installed flawlessly (and worked with a Jupyter notebook.)

I am guess that the temp space needed is fairly large.

Really want to thank those who replied. Now I can go on to converting my Mathematica programs.
