“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.

How to check connection between windows and anywhere usb with nagios

The easiest way to monitor the connection between your Digi Anywhere USB device and a server is to monitor the USB device connected it. I use Nagios to monitor several indicators in each server, and the following script can be used to monitor if USB devices are connected:

strComputer = "."
 
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colDevices = objWMIService.ExecQuery ("Select * From Win32_USBControllerDevice")
 
For Each objDevice in colDevices
    strDeviceName = objDevice.Dependent
    strQuotes = Chr(34)
    strDeviceName = Replace(strDeviceName, strQuotes, "")
    arrDeviceNames = Split(strDeviceName, "=")
    strDeviceName = arrDeviceNames(1)
    Set colUSBDevices = objWMIService.ExecQuery ("Select * From Win32_PnPEntity Where DeviceID = '" & strDeviceName & "'")
    For Each objUSBDevice in colUSBDevices
        'Wscript.Echo objUSBDevice.Description
        If objUSBDevice.Description="SCR3311 USB Smart Card Reader" Then
           WScript.Echo "OK - Card reader detected"
           WScript.Quit 0
        End If
    Next
Next
 
WScript.Echo "WARNING - No card reader detected"
WScript.Quit 1

In my case, I monitor a card reader that identifies as "SCR3311 USB Smart Card Reader". You should type the exact name of the device you're monitoring at that spot. If you don't know the exact name of the device, uncomment the line
'Wscript.Echo objUSBDevice.Description
and then execute
cscript //nologo //t:10 "check_cardreader.vbs"

Put above file in c:\program files (x86)\nrpe\check_cardreader.vbs and update nrpe.cfg to contain:
command[check_cardreader]=cscript //nologo //t:10 "c:\program files (x86)\nrpe\check_cardreader.vbs"

After restarting the NRPE service, you're ready to monitor the USB device.© GeekLabInfo

Windows 7: Using symbolic links

Linux and unix have had this nifty little feature called symlinks (symbolic links) for decades. Windows has finally caught up with the new command mklink.

Windows Vista introduced the new command mklink, which was expanded in Windows 7.

Syntax

MKLINK [[/D] | [/H] | [/J]] Link Target
 
        /D      Creates a directory symbolic link.  Default is a file
                symbolic link.
        /H      Creates a hard link instead of a symbolic link.
        /J      Creates a Directory Junction.
        Link    specifies the new symbolic link name.
        Target  specifies the path (relative or absolute) that the new link
                refers to.

Examples

Link d:\myfile.txt (the file) to c:\something.txt (the link):

mklink c:\something.txt d:\myfile.txt

Make some crappy old program save its data to your fileserver directly by linking \\fileserver\data (target) to c:\program files\crappy-old-program\data (the directory).

mklink "c:\program files\crappy-old-program\data" \\fileserver\data /d

Use dsacls to gain access to active directory policies

I've locked myself out of group policies a couple of times. When this happens to you, you can gain access again running the following command:

dsacls.exe "CN={GUID},CN=Policies,CN=System,DC=local" /R "Authenticated users"

MS Paint: Insufficient memory

One of my users got an annoying message when starting MS Paint (mspaint.exe):

Onvoldoende geheugen of bronnen om de bewerking te voltooien. Sluit enkele programma's af en probeer het opnieuw.

Which means:

Insufficient memory to complete operation. Close some programs and try again

Other resources suggested that the file opened was too big or that we're doing something with a .tiff file. But he was just starting paint, no images involved at that point. The solution was to open regedit and remove the following key:
HKCU\Software\Microsoft\Windows\CurrentVersion\Applets\Paint
That reset all MS Paint settings and we could start paint again.© GeekLabInfo

Minimize Google Talk at startup

Google Talk has a function to automatically start on boot. However, it cannot minimalize automatically. To run Google Talk minimized by default, you'll need to use some external software.

CMDOW

I'm using a tool named cmdow to do the hiding for me. Cmdow is an extremely useful tool for showing, hiding, minimizing, resizing and closing windows. Unfortunately, some malware uses this functionality as well. Therefore, your virusscanner may tag cmdow as malware, but it actually isn't.

Scripting

Google Talk starts 'on boot'. Just a few seconds later we need to run the cmdow command. To do this, we create a .bat file in the Startup folder.

@echo off

rem The next line hides the batch file execution

cmdow @ /hid

rem The next line delays the batch exec for 4 seconds.

ping localhost

cmdow "Google Talk" /HID

Printing from a CUPS server to Windows 7

A colleague of mine has some family issues that require him to be home more often. However, work continues. So he started working at home with a laptop. Nothing special about that. What is special, is that we're running a piece of software ("RR") that has old-style telnet-like terminals, which is sending it's print jobs straight to the printer.

His laptop has a direct VPN connection to the company network, but his printer doesn't.

Network info

The old software ("RR") is running on a pretty new RHEL 5.6 installation. It uses CUPS to queue and deliver print jobs. In my situation, the RR printer has zero printers configured, there's another Linux server that has all printers configured and broadcasts those printers over the network. But you could leave that print server out.

Problem

RR cannot reach the printer directly. But it can reach the laptop, which is running Windows 7 Professional. I searched for an IPP server that I could install on Windows, so that the printserver could use that to relay messages to the local printer, but I couldn't find any.

Solution

Windows 7 still has the option to install an lpd server. It's not installed by default, but it's very simple to install.

Windows setup:

  • In the Windows 7 Control Panel
  • Go to the "Programs and Features"
  • Click "Turn Windows Features on or off"
  • Turn on the LPD protocol.
  • Now go to the "printers" and share all printers you want to share.
  • Don't use long names and names with spaces, like "HP Laserjet 4200 Series", which are hard to setup on the client. Use something short like hplj4200.

Client setup:
Now you can setup the client to print to lpd://[ip-or-hostname-of-client]/[printername], for example lpd://10.10.10.17/hplj4200

If you can't get it to work, please check printer permissions and the firewall of the Windows 7 machine, which must have port 515 open.© GeekLabInfo
