Hi everybody, my first post so please bear with me!

 

Windows 7 Pro X64

 

Unable to start On Screen Keyboard (OSK) either from ease of access centre or running Application  C:\Windows\System32\osk.exe.

Just get Pop up error 'Cannot start On Screen Keyboard'

 

Things Tried so far:

 

Have run SFC /Scannow and all files correct

SURT ran no problems updates

Booted in both Safe and Clean modes

Created a test account in case profile corrupt

No Lockdown Progs installed, just Avast Free and Winpatrol

Run CHKDSK and 2 third party disc checkers and HDD Healthy.

 

All of above to no avail.

 

At loss on how to proceed further.

Help anyone Please.

May or may not work. Turn off Table PC Components. Reboot. Turn on again.

Right click the OSK.exe file and select Properties. What is the size in bytes?

I have Win 7 64bit but not Pro. It shouldn't make a difference though. I need about 10 minutes or so and then I will post what I get for a size.

 

My sizes are the same.

 

Right click the osk.exe file and under the security tab do you have checkmarks next to read&execute and read? Click the Advanced button and under the Permissions tab make sure Trusted Installers have full control. Administrators, System, and Users should have read/execute permissions.

Open the registry, browse to the following key

 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI

 

Does Show Tablet Keyboard have a Dword value of 0 or 1. Change it to 1 if it's a zero.

 

Other than that I am out of ideas, sorry. I don't know if it would make much of a difference but I could upload my osk.exe file to Dropbox and PM you a link.

It's also suggested to run System File Checker

https://www.lifewire.com/how-to-use-sfc-scannow-to-repair-windows-system-files-2626161

 

If that don't work you most likely have a corrupt User account. 

 

Have you ever tested your HDD to see if it is healthy?  Corrupt files may be due to a bad Hard Drive, the first thing to go in most computers.

Hi all,

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI  :

 

Had Dword of 0 Changed to1 as suggested and re-booted but no change. Put back to 0

 

As mentioned in opening post SFC has been run several times and all clean.

New account created to eliminate possibility of corrupt profile

CHKDSK and 2 third party progs run to check HDD. All Clean and OK.

 

John_C21

Yes, please upload OSK.exe its worth a try.

 

Thanks everyone for your help.

 

Magdalene

It will be a bit before I get a chance to PM the Dropbox link. Copy the file to your desktop and double click it. If you still get the error then something is going on in Windows. If it brings up the On Screen Keyboard then replace the osk.exe in System32.

 

Edit: Check your PM.

Did you see this Microsoft thread? It could be related to a bad update albeit the update was in 2014.

 

 

This is due to a bad Windows update. Remove KB3004394 from Windows Updates and restart. It has caused numerous issues.

 
Go to Windows Updates. It should be listed in Start | All Programs, or you can find it in the Control Panel.
 
Click on View Update History and then Installed Updates. In the search bar type in KB3004394. When it shows the update, right click on it and Uninstall.
 

Microsoft has pulled the update so you don't have to worry about it coming back.

KB3004394 never installed. Ran 'Silver Bullet' Patch KB3024777 just to be sure.

That all the ideas I have other than the possibility of the program being restricted in Group Policy but if that was the case you would get a small dialog box noting as such. This is one of the strangest problems I have seen. You have done everything possible.
