[SOLVED] Java update “Failed to download required installation files.”

There have been a few occasions recently where a Java update fails


Java Update failed to download the required files

Having looked about for a solution, there is two methods that i have found to quickly rectify the problem.

1) The cheats way.
Re-install java on top of itself.

NB, Java has many different versions depending on which OS and update version of the OS you are using, the quickest way to re-install with the latest version i have found is to use Ninite. This will find version and install it correctly for you.
https://ninite.com/java8/

2) Edit compatibility settings on the Java updater.

go to: %PROGRAMFILES%\Common Files\Java\Java Update

and find jucheck.exe (updater)

right click --> Properties --> Compatibility

select the tick box to run with a previous version of windows, anything before Vista seems to do the job. (XP, Win95 etc…) As this is just the updater and not java, it ensures you still get the correct version.

BONUS 3)
This seems to be an issue with privilege elevation in windows – if you have access to an admin account, then you can log into that then try updating 8/10 it works without the above.

Check if PC is joined to the domain

Here is a quick way to check the health of a PC joined to a domain controller. This is very useful if you need to do a quick check in the first instance of diagnosing a trust relationship issue.

pc is joined to the domain

Here are the steps to check if a pc is joined to the domain using Powershell:

1) Open up a powershell console

2) Type or copy/paste the following, replacing the *dc mane* with your networks domain controller

Test-ComputerSecureChannel –Server *dc name* -Verbose

3) check results, If it comes back with red text it is a pretty good indicator that there is some form of problem going on, however if it returns “The secure chanel between ‘*’, ‘*dc name*’ and ‘*domain*.local’ is alive and working correctly”  then you can continue investigating your problem knowing that the PC is nice and safely connected to the domain.

Set server to automatically update time

If you have ever been in the situation where a time server or an old server will just not keep in sync, perhaps due to a CMOS battery error, or simply old hardware, then this cmdlet is for you.

Here is how to set a server to automatically update time;

automatically update time

Open up a command prompt and copy/paste the below:

w32tm /config /manualpeerlist:”0.pool.ntp.org 1.pool.ntp.org 2.pool.ntp.org”,0x8 /syncfromflags:MANUAL
w32tm /config /update
net stop w32time
net start w32time
w32tm /resync /nowait

All that this is now doing is setting the clock to update automatically from a web time server, the servers we are using are the public pool 1, 2 and 3 at ntp.org
We stop and start the time services, and then tell it to resync with the new settings.

Windows Update stuck 3 of 3 – Can’t use PC

It would seem that the last batch of updates from Microsoft around the 12th-14th May 2015 have been causing quite a few PC’s to hang stopping at Update 3 of 3.

This so far looks like it is only affecting Windows 7 Pro X64 based PC’s

As with most IT Professionals, we would never suggest performing a Hard shut-down to your PC, unless there really is no other option, however it does look like in this case this is the only way to fix this particular ‘Stuck Update‘ issue.

If your Windows Update  stuck: windows update stuck 3 of 3

Option 1)

Press CTRL + ALT +DEL
This seems to be working for 50% of users encountering this issue, if it does not work then proceed to option 2.

Option 2)

Step 1) Hold down the power button on your PC for 10+ seconds,
Step 2) Restart PC by repressing the power button
Step 3) If confronted with a windows error ‘Your PC did not shut down normally’ screen, select “Start Windows Normally”

Out of the 7 PC’s we have now done this to, all in different environments, we are yet to see any errors or corruptions caused by this. We are continuing to look into which update specifically caused this and why, and so check back later to keep yourself updated.

Use CMD or Powershell to find last boot time

Ever wanted to check the last boot time of a PC or server?

There are multiple reasons why you may want to find out the last boot time of a server or a PC, Perhaps your server has been restarted without you knowing, and you want to be able to have a starting time to aid in your search through event logs to see what happened prior to the restart. Maybe you are remotely logged onto a PC which is running slow, but the user hasn’t restarted it for a while.

Anyhow, below is how to check the last boot time using either Powershell or CMD:

Powershell:
Get-WmiObject -class Win32_OperatingSystem | Select-Object __SERVER,@{label=’LastBootUpTime’;expression={$_.ConvertToDateTime($_.LastBootUpTime)}}

last boot time using powershell

CMD Method:

The built in systeminfo command may however be easier to remember using CMD:

systeminfo | find /i "Boot Time"

Or with the help of WMIC:

wmic os get lastbootuptime

wmicLastBoot

 

As you can see, the easiest and probably most useful quick command is by using SystemInfo, easy to remember, quick and nicely formatted.

 

Can’t use browser – Jump to URL (hh h)

Ever been stuck with a web browser so full of toolbars or extensions that its almost impossible to do anything? Is your browser unresponsive or you are unable to use the internet?
Then you need to deploy the Windows hidden Cutdown browser:

Here is how to access the web when you can’t use browser.

Simply use the following hotkeys Win+R  to open the Run box, then type “hh h” and hit enter
Cutdown web browser HH H useful can't use browser

This will bring up the ‘HTML Help’ documentation window,can't use browser

Right Click and select ‘Jump to URL’
Cutdown web browser HH H

Enter URL of site you need, in this case a copy of RKILL to help get pc back into shape,
Cutdown web browser HH H

Resolve Logmein Error 4320 (Method 2)

 

 

 

Another way to resolve Logmein Error 4320 

As discussed in my previous article on this logmein issue, this error code is most commonly found in a domain environment, or where there may be some form of user lockdown, and may even occur on a multi user non domain PC.

Basically, it is meant to protect the users PC from being accessed by someone other than the logged in user who installed logmein in the first place.

  1. First off, lets open up the logmein Control Panel (Right-Click on the logmein icon in the taskbar, or open from the start menu)
    Add users logmin
  2. Next we are going to select ‘Options’
    Add users logmin
  3. Then ‘Preferences’
    logmein properties
  4. Select the ‘Security tab’
    logmein properties
  5. Click on ‘Show Details’
    Error 4320
  6. Click on  Browse and select the correct user you want to add to allow access to the PC. You can choose from a list either by selecting the local PC name, or if you are on a domain, then the domain name that the PC is registered with.
    Logmein Error 4320
  7. Click OK to close all windows, Turn off Logmein then turn it back on,
  8. You are good to go!

 

Preventative measures could be taken however, When installing logmein, if you do so whilst logged in as a local admin for the PC, this seems to resolve the issue. Please note, this is only for the LOCAL admin for the PC, a domain admin account will most likely not work, and provide the same Logmein error 4320 as discussed above.

Resize VHD / Shrink Virtual xp Disk

So you still have something running on that Virtual XP machine silently consuming space on your HDD?
Finally decided that you need to resize VHD disks to free up wasted storage? Here is how;
Run out of space HDD

This process will assess how much space is currently being used, and the, remove the rest leaving 10-20% headroom for growth of the disk. It can take up to 30+ mins to complete this process, so be patient! By using this simple tool, you can shave a good 60+GB of wasted space into freely usable storage.

Resolve Logmein Error 4320 (Method 1)

How to resolve Logmein Error 4320 

Whilst setting up logmein for remote access in a pretty locked down domain environment, I have noticed that quite frequently we would get an ‘admin error 4320’ on the remote users PC.

Now the official logmein site would suggest adding users within the logmein interface, which we will cover in ‘Method 2’ however I have found a quicker workaround that works 9 out of 10 times is by simply always running the program as administrator.

  1. Place the Logmein icon either on your desktop or navigate to the program folder path usually “C:\Program Files (x86)\LogMeIn Ignition”
  2. Right click on the icon and select ‘Properties
  3. Once in Properties select the ‘Compatibility’ tab at the top
  4. At the bottom under ‘Privilege level’ tick the ‘Run this program as Administrator’ box*.
    How do I resolve Error 4320
  5. If you have more than 1 user on the PC, select ‘Change settings for all users’
  6. Again tick the ‘Run this program as Administrator’ box
    Logmein Error 4320
  7. OK out of both windows, If logmein is running. Close it again and re-open it, now using an Administrative logon.

Your Logmein error 4320 should now be resolved. if not see the link below

*If the ‘Privilege level’ box is greyed out, be sure that you are logged on as an administrative user, or log off and back on as one in order to continue.

Top 5 Obvious but little known useful cmdlets and IT support tricks

As an IT technician, I am often adding new quick tricks to my mental shorcuts list, here are my current top 5:

  1. Need to log onto a domain as the local PC admin but don’t know the PC name?
    Simply use ” .\” at the start of the admin username to log on as a local PC user.
  2. Powershell if PC has trust relationship
    Test-ComputerSecureChannel –Server *dc name* -Verbose
  3.  shutdown /i (-i ) remote shutdown
  4. Create big dummy file:
    Cd \sysinternalssuite
    Contig -n 2gbEmptyFile.txt 20000000
  5. For Spooler Crashes, first try below to clear all jobs
    net stop spooler
    pause
    del /S /F “C:\Windows\System32\spool\PRINTERS\*”
    net start spooler
    pause
