    • The file extension changes to .solitairetheme8 if Microsoft Solitaire Collection is installed

    • I am experiencing this problem as well, and I know of several other who are, also.

      Over 5 months and no response (or fix) from Microsoft?

    • Can this issue be reopened? It is reproducible by having Microsoft Solitaire Collection installed when attempting to download Marcelo’s file. The issue has its roots in how Microsoft Edge determines what file extension to give downloads.

    • We are no longer able to repro this issue. If you are still seeing problems, can you provide additional information? Versioning information, screenshots of the difference, etc.

    • Hi Kelly. I attempted to download a .tgz file from (The linux install) but this showed up, regardless which file, as a .solitairetheme8 file extension.

      I uninstalled solitaire so it works now. Thanks Braxton for your idea of uninstalling solitaire.

    • I got the same problem on a Windows 10 with Chrome.

    • From what I’ve seen now (since I’m not a Windows Insider), the bug was producible in the Anniversary Update but it’s been fixed as of the Creators Update

    • I’m running the latest insider build and this is still an issue.

    • I’m not on an Insider release - just running the base Creators update - and this is still happening, so it is definitely not yet fixed. I am using Chrome too.

    • Same issue occurs with latest edge version “Microsoft Edge 40.15063.0.0” in creators update. I tried to download the kafka_2.12- from my local web server but it is downloaded and saved locally with .solitairetheme8 extension instead of .tgz.

    • Same issue when downloading cudnn 7.0.3, on fresh Chrome, on Windows 10 (version 1709, build 16229.19).

    • This is obviously a real issue happened to many people.
      I don’t know how Microsoft says:
      "NOT REPRODUCIBLE Issue #8475572". This cannot be serious.

      Anyway, this issue is that IE automatically rename .tgz to some solitairetheme file extension, which is ridiculous. I removed that app from windows 10. Not sure if it’s going to help.

      BTW, why do I use IE? Because EDGE is extremely slow and has issue with MS’s own input method.

      Windows support is almost nonexistence these days.

    • I don’t think this is an IE bug, it also happens in Chrome on Win10.
      Noticed on nvidia’s cudnn download page.
      Thankfully I really don’t need solitaire collection, so it’s kinda fixed for me by uninstalling it.

    • Thanks for the bug report. The root cause of this issue is understood (when Microsoft Solitaire Collection
      is installed, it creates overwrites the
      value of
      HKEY_CLASSES_ROOT\MIME\Database\Content Type\application/x-compressed
      to .
      ) and it has been assigned to the correct team for followup.
