Hi visuman,

that error message is generated either by Windows or by OSK.exe as can be seen by its text. If the osk.exe wouldn't be found the text would be different!

OSK is found, but can't be started - that's quite a different error message!

I suspect it's some kind of access right problems...

HI GerdW,

Yes, its unable to start the exe. I have Admin privileges still unable to access OSK from LV.

But in another PC, i am able to do it.

Am just curious to know ,why its not happening in my laptop.

it seem to be an issue with access rights. if i use a different useraccount it won't work for me as well.

but interestingly it works out of the temp directory

C:\Users\username\AppData\Local\Microsoft\Windows\Temporary Internet Files\keyboard.vi

so i figure a batchfile with runas should hopefully do the trick. i will give it a try

Give this a try hopefully it works for you

Hi Bijay

yea i see your troubles and i bet you have tried all different prossible ways.

this might be not the best solution but since system32 either require adminrights to call osk. you either have to create a batch or vbs ... or whatever to call osk.exe with adminrights.

An different approve would be to create a copy of the file C:\Windows\System32\osk.exe in your project and call this one, you should have the rights to call this file (osk.exe)

To test it i copied the osk.exe on my desktop. This might be an option

[Bijay]

I copied osk.exe to desktop and gave the path as mentioned but still can't access from LV.

But really its a good learning for me. 

I hope Visuman gets his issue resolved and post the solution soon
