Windows Uninstaller for Anaconda deletes Users folder #11726

Open howardhshen opened 4 years ago

howardhshen commented 4 years ago

I was testing some installation setups for Anaconda, which required me to uninstall Anaconda and reinstall it. When I did this a few days ago, everything was fine, but when I did this today, the Anaconda uninstaller removed all the files in my Users folder, which included all my documents, pictures, downloads, etc. The main difference is that my last installation, I installed for "All Users" instead of the current one. However, when I tested this afterwards, both installation types resulted in the Users folder being wiped.

Actual Behavior

Use Windows Programs and Features menu to uninstall Anaconda. Anaconda is uninstalled. All files in Users folder also deleted. All folders and subfolders remain, but are empty.

Expected Behavior

Use Windows Programs and Features menu to uninstall Anaconda. Anaconda is uninstalled.

Steps to Reproduce

  1. Install Anaconda (either for All Users or Just Current One)
  2. Uninstall Anaconda via Windows Programs and Features menu.
  3. Check Users folder.
Anaconda or Miniconda version:

Anaconda3-2020.02-Windows-x86_64.exe

Operating System:

Windows 10

We are not able to reproduce the issue on windows 10x64 bit for the Anaconda3 installer. It is tested on the following installations:

The output from the uninstaller in the second comment also does not indicate that it deleted everything in the home folder - everything is under the \anaconda3\ directory.

Can you provide any additional insight or log information?

howardhshen commented 3 years ago

Sorry to leave this issue open for so long; I didn't have a chance to test until now as I didn't want to risk losing all my files again.

I tested this again today, using the installer for the 2020.11 version, and the problem appears to be unique to my device.

The only other notable difference that I know of between the two devices is that the path on the first has a space ("C:\Users\Howard Shen\anaconda3"), and the path on the second does not ("C:\Users\chowd\anaconda3")

When I tried to uninstall Anaconda, it attempted to delete the user folder instead of the Anaconda folder under the user directory. It also marked them for deletion during the reboot phase. It was a complete nightmare. When I restarted, I couldn't log into my machine, and all my documents and application settings were erased. The recovery application called Recuva didn't work either. Please fix this bug immediately or remove the uninstall application to prevent others from experiencing the same issue. WhatsApp Görsel 2023-05-31 saat 19 13 22

Thank you for reporting this! I am trying to replicate the problem and made some progress, but I need some additional information.

  1. Which Windows version are you using?
  2. How was Anaconda installed? Which directory was Anaconda installed into?
  3. How was the uninstaller executed? If it was executed in Windows Explorer, where was it located?
  4. Did you see any errors pop up during the uninstallation? For example, that it failed to run "pre_uninstall" or similar?
cenkersisman commented 1 year ago

Hi, here are the answers:

  1. Windows 11 Home 22H2
  2. c:\users\cenke\anaconda3 3.It was downloaded from Chrome and the executed file was Anaconda3-2023.03-1-Windows-x86_64.exe 4.No there was no errors.
marcoesters commented 1 year ago

Could you elaborate on how you uninstalled Anaconda? Did you use "Add or remove programs" or executed the Uninstaller (Uninstall-Anaconda3.exe) from Windows Explorer?

If it's the Windows Explorer, where was the Uninstaller file located?

cenkersisman commented 1 year ago

I executed the uninstaller from windows Explorer.

And I assume the uninstaller was located inside c:\users\cenke\anaconda3?

I have so far only been able to reproduce this bug by moving the uninstaller outside this directory, but that produces additional errors that come with an "abort/retry/ignore" message box.

Hello, A similar issue occured today. I use Anaconda Navigator 2.5.0. Operating system is Windows 11 When I tried to remove an environment located at different folder i.e. c:\python\programs\anaconda3 from Environments tab of the navigator, it deleted the anaconda3 folder and removed programs folder and python folder as well. Hopefuly there was no files other than anaconda3 in python folder. But it frustrates me a lot. It deletes all back folders..

Sorry to leave this issue open for so long; I didn't have a chance to test until now as I didn't want to risk losing all my files again.

I tested this again today, using the installer for the 2020.11 version, and the problem appears to be unique to my device.

  • I tried 4 times on the original device (a Lenovo T480), and each time, it deleted the files in my Users folder but left the file structure intact. If I had a file open in another program, the file would not be deleted, but everything else would be. I can 100% replicate the error on this device, and can actually see the files disappear in Windows Explorer while the uninstaller is running. The files are deleted either very late in the last "Execute:" step, or occurs in one of the following steps (those steps are very quick and it's hard to pin when the deletion occurs.
  • I also tried installing and uninstalling the 2020.11 version on a second computer (Dell Inspiron 5577, Windows 10), and could not replicate the problem. I installed and uninstalled twice just to make sure.

The only other notable difference that I know of between the two devices is that the path on the first has a space ("C:\Users\Howard Shen\anaconda3"), and the path on the second does not ("C:\Users\chowd\anaconda3")

Thanks for reminding a lot. I tried many ways to uninstall Anaconda3 in many ways including control panel and program management but failed. Then i through Lenovo PC Management to uninstall it and it worked. I think it might be the issue about the device.
