“Logi Capture cannot install, requires restart”. How to fix?

A lot of people are complaining about being unable to (re)install Logi Capture, the software that comes with modern Logi (formerly known as Logitech) webcams.

The complaints

For example, Sasha says: "Logi Capture Version 2.06.8 will not complete installing on my Windows 10 PC. The .exe file immediately jumps to a "Restart Required" screen, and upon reboot nothing happens.  Have cleared regisistry and removed all other logitech files.", to which the customer support gives an answer that indicates they didn't even read the question.

Michael says: "can't install Logi Capture software for my Brio anymore. I get the restart required splash screen after clicking the exe. Restart doesn't solve the issue. Cleaning up the registry doesn't help either. using Win 10 (1909)"

And Jason says: "I just uninstalled Logitech Capture  2.00.226 from my Windows 10 64bit. Then I went to install it again as an Admin, but I now get a window telling me, Restart Required - "Restart is required to continue with LogitechCapture installation." I have followed this process 3 times, with no installation complete. FYI- I have Skype for Business and ZOOM installed on my machine. Skype and another Softphone client that has video conferencing login upon startup."

I think I figured out how to fix this issue. I first installed version 2.08.11, which has some bugs. After removing that version, I ran into the same message trying to install version 2.06.12. Restarting the computer didn't fix anything.

My analysis

It seems that when uninstalling LogiCapture, the old version leaves uninstall instructions in the registry, the LogiCaptureSetupNeedReboot key in the RunOnce section to be exact. The installer expects Windows to run a command based on that, and then remove the data from the registry. It is normal for uninstallers to do such a thing, but Logi has done it wrong: when you're running a 64-bit computer, it writes to the 64-bit registry. Apparently, Windows doesn't even look at the 64-bit version of the registry for RunOnce entries. Therefore, after uninstalling the software from a 64-bit computer, you can never reinstall Logi Capture anymore.

My fix

Fixing this issue is simple. Just remove the wrong entry from the registry

click start
type "cmd" and then press ctrl+shift+enter to run cmd as administrator
then in the command line screen, type:

reg delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce /v LogiCaptureSetupNeedReboot /reg:64

(on one line)

After this, I could start Capture_2.06.12.exe or Capture_2.08.11.exe to reinstall Logi Capture.

Please use these tips at your own responsibility.

The real fix

Of course, Logi should fix this in their installer/uninstaller. But given that version 2.08 introduced an annoying message in big red letters to push you away from Logi Capture to another product, I don't think we'll get a real solution soon.

chattr and lsattr in Python

Apart from changing the rwxr-xr-x like permissions, some Linux filesystems have another way of protecting files. You cam make them IMMUTABLE, after which no program can change them. Not even if you have the right permissions. Python however does not support reading or writing the immutable attribute.

Inspired by yellowcrescent, I just wrote the following code snippet for my own use:

# Code from geeklab.info
import fcntl
from array import array

# FS constants - see /uapi/linux/fs.h in kernel source
# or <elixir.free-electrons.com/linux/latest/source/include/uapi/linux/fs.h>
FS_IOC_GETFLAGS = 0x80086601
FS_IOC_SETFLAGS = 0x40086602
FS_IMMUTABLE_FL = 0x010

def chattri(filename: str, value: bool):
    with open(filename,'r') as f: 
        arg = array('L', [0])
        fcntl.ioctl(f.fileno(), FS_IOC_GETFLAGS, arg, True)
        if value:
            arg[0]=arg[0] | FS_IMMUTABLE_FL
        else:
            arg[0]=arg[0] &~ FS_IMMUTABLE_FL
        fcntl.ioctl(f.fileno(), FS_IOC_SETFLAGS, arg, True)

def lsattri(filename: str) -> bool:
    with open(filename,'r') as f:
        arg = array('L', [0])
        fcntl.ioctl(f.fileno(), FS_IOC_GETFLAGS, arg, True)
    return bool(arg[0] & FS_IMMUTABLE_FL)
    
f="/root/testfile"
print("Yes" if lsattri(f) else "No")
chattri(f,False)
print("Yes" if lsattri(f) else "No")
chattri(f,False)
print("Yes" if lsattri(f) else "No")

Use it as you like, at your own risk. If possible please link my website.

Keep in mind that only users with root-access can change file attributes.

msiexec /package {90120000-001A-040E-0000-0000000FF1CE} /uninstall {BBE4FD45-34D1-4497-8F75-77965C4E044D} /qn /quiet /norestart

Or remotely:
psexec \\computername "msiexec.exe" /package "{90120000-001A-040E-0000-0000000FF1CE} /uninstall {BBE4FD45-34D1-4497-8F75-77965C4E044D} /qn /quiet /norestart"

Windows 7 and Windows 8 updates slow

The last few months, I've noticed brand new clean Windows 7 installs have a hard time updating for the first time. Doesn't matter if they are updating from the original Microsoft update service of from a WSUS server, the time until the first update sometimes can be hours.

This update is supposed to fix that. I haven't tried it myself yet:

Fix idealcheckout_unserialize

Sorry, I don't feel like typing a message dedicated to this fix I made. Let's just post the code.

Original code:

function idealcheckout_unserialize($sString)
    {
        // Recalculate multibyte strings
        $sString = preg_replace('!s:(\d+):"(.*?)";!se', "'s:'.strlen('$2').':\"$2\";'", $sString);
        return unserialize($sString);
    }

Error:

PHP Deprecated:  preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in ... on line ..

This means idealcheckout_unserialize is not php7 compatible.

My fix:

    // Unserialize data
    function idealcheckout_unserialize($sString)
    {
        // Recalculate multibyte strings
        $sString = preg_replace_callback('!s:(\d+):"(.*?)";!s',
            function($matches){
                return 's:'.strlen($matches[2]).':"'.$matches[2].'";';
            }, $sString);
        return unserialize($sString);
    }
