Anaconda 3 installation error - no scripts folder and no conda command prompt and shortcuts

Question

I am trying to install Anaconda3-2019.10-Windows-x86_64.exe on window 8.1. During installation, I checked details and there seemed have many issues.

• No Scripts folder or Conda Command prompt or shortcuts were created.
• Only conda-meta, Lib, pkgs,_conda.exe and Uninstall-Anaconda3.exe are created.

I tried 32 bits also and miniconda versions. All of them don't work for me. I already tried multiple uninstallation and installation. But the result is the same.

any inputs will be very helpful.

During handling of the above exception, another exception occurred:

Answer 1

Global search for the file .condarc in the drive you installed in. Uninstall anaconda and delete .condarc file. Reinstall Anaconda and you should be good to go. Was stuck with this problem for hours, hope this helps!

Answer 2

This problem still exists in Anaconda3 2021.11. I suspect the problem is in the username (might be that this occurs only with certain localizations). If the username has special characters or space the AppData/Local/Continuum folder will simply be missing. What is unacceptable is the installer telling the installation was a success.

If you install it globally you will still not be able to use it when you create a new enviroment (It tries to put it in the user folder, succeeds, then doesn't find anything when eg. you try to install new packages to this env). (This might be dependent on other localization settings too)

Solution is to create a simple user folder like instead of Kovács Xaviér make it KovacsXavier (I'm sure the Caps doesn't bother it). Now you will be able to install it.

If you have a new windows installation you can trick windows into creating such a short username by adding this as your "UserName" first and later renaming yourself. The directory created will remain the same but you can rename your displayed name later. I really doesn't recommend anyone letting Windows create a fancy named home folder. Not anaconda is the only software that has problems with this.

Another notable observation that you better leash your antivirus software when installing Anaconda.

But it is obvious Anaconda doesn't check software integrity after install. Which is sad.

This issue can be eradicated by uninstalling the current version of conda and install the previous version of anaconda anaconda 2019.03. It will help solve the issue.

Answer 4

For me, it's the opposite. When i used the installers from 2020, Anaconda is installed in C:\Users\username\Anaconda3. This gives me the same problem as you with no Scripts folder, no command prompt, no Anaconda Navigator. I tried the 2019 version and now Anaconda is installed in C:\Users\username\AppData\Local\Continuum\anaconda3 and it works.

Maybe changing the install path for the 2020 versions would have worked too. I didnt try it though. I have Windows 10 and used the x86_64 files.

Answer 5

Finally, I used 64 bit preview version of installer from from 2020 Feb. The installation was completed successfully now and everything is working fine. I suspect there is issue with 2019.10 verion which might have caused problems.

Thanks to the github conda issues page which leads to this solution.

Make sure to check hash values of your installer just for in case too.
