Unable to Install AI Assistant: LZMA Codec Not Supported
Unsolved
Qt Creator and other tools
-
Hello everyone,
I am facing an issue while trying to install the AI Assistant extension in Qt Creator. Here are the details of my problem:
Error encountered:
When I try to install AI Assistant via the Extensions interface in Qt Creator, I get the following error:
Running C:\WINDOWS\system32\tar.exe xvf C:/Users/masto/AppData/Local/Temp/QtCreator-NEzDNX/dHfpDr-Asset in "C:\Users\masto\AppData\Local\Temp\QtCreator-NEzDNX\plugininstall.YCcvgb". tar.exe: LZMA codec is unsupported tar.exe: Error exit delayed from previous errors. Command failed.It seems that the issue is related to the LZMA codec, which is not supported by the version of tar.exe used by Qt Creator.
How can I resolve this issue to install AI Assistant successfully?
Is there an alternative way to manually install the extension?Config :

Try out Qt Creator 16.0.0. We changed the order of searching tools on the machine that could unpack a
7zfile.Otherwise do try to install https://www.7-zip.org/ on your machine.
