WinRAR error: Unknown option "optemp" (Update WinRAR to fix)

Hi,

I have WinRAR set as my default archive program. It seems recently the command line parameters have been changed and now get this error when it attempts to unpack:

Hi man, thanks for the bug report. I will investigate this ASAP!

Interesting, I cannot reproduce this issue, @H3X1C what's your WinRAR version?

[H3X1C]

WinRAR 5.71, I know an older version. Checking I don't think this version supports the optemp arg. I see you recently refactored the process spawning logic: https://github.com/ElPumpo/TinyNvidiaUpdateChecker/blob/ce6e311466d36c4632170b356d1db77ef8b55467/TinyNvidiaUpdateChecker/MainConsole.cs#L902 This would explain why it previously worked and now doesn't for my version.

Guessing the aim is extraction to a folder called temp overriding existing files. If so the following works on my version: "c:\Program Files\WinRAR\WinRAR.exe" x HardwareManagerSvc.zip -o+temp

Was the p in -optemp a typo?

@H3X1C be wary of versions before 6.23 https://nvd.nist.gov/vuln/detail/CVE-2023-38831

Yea update WinRAR, that will fix the problem, seems like that old version doesn't have this CLI argument. I agree with you it looks very weird, but apparently that's how they developed it. If I were them I would have something like a = char to sepeate arg and its value.

This is new code because we now extract the full driver file and then query all components, display to user which chooses which ones he wants.

Also like Mr Tech is advising you.. update! It has a CVE

Just wanted to say thanks for the resolve, I was having the same issue and have thus resolved it after reading this!

[ElPumpo]

Perhaps if this secondary argument works on both version I might change it

EDIT Yea i dont think i am going to address this issue. Just update winrar
