I have tried updating with iTunes but failed. I thing I lost most of the installed software.
I succeeded in downloading to my PC iOS11 but can't flash it to my device. Being used
to windows system I need some guidance on how to install downloaded iOS11?
It's npt clear what you are talking about.
IOS11 is the operating system for iPhone /iPad etc. It's not windows software. You'd normally update it over the air without a WindowsPC or mac. However if your IOS device will not function well enough to do that then you can recover it by connecting to a PC via a cable through the iTunes software (which is the application that runs on the Windows PC or mac).
See the following instructions If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support
If your iTunes software itself is damaged, to may need to reinstall it or repair it. See these articles (use whatever seems appropriate for your situation - don't blindly do it all!...

If you need further assistance, please try to describe to us exactly the steps you are taking and what is happening when you perform them.
No problem, I suppose that you've googled 'jailbreak' now? Without detail about why you were trying to 'flash' the device (and assuming that you didn't find the recovery steps in the first article useful for some reason), I'd assumed that the phone had firmware had become damaged in a way that should not be possible in normal usage.
If you do need further help, please do try to post information about exactly which steps you followed and what exactly you observed.
Also any information was to why you think that the phone's software is corrupted would be useful.
For example instead of reinstalling IOS, you might try resttting thr device to facory settings

my device software is corrupted and damaged, App update software is either missing or corrupted. It does not show. I am trying to install ios11 on a clean hard disk. I have downloaded ios11 and saved on my Windows 7 pc. I tried but cannot flash because it is different than Windows language. Shall appreciate guidance.
The first link in my post above is the lowest level recovery available to the end user.
I'm not sure what you mean by "accidental deletion of software". If you've tried to jailbreak your device and that went wrong then you've got a very expensive paperweight as nobody will be able help you here.
I'm unable to assist on this further.

My device had accidental deletions of software. Tried software update but cannot access this application on my device. Is there a procedure to flash ios11 directly to
the device?
I had never heard of jailbreak. Thanks for educating me.
Presently my device can call and receive calls and messages.
I plan to follow ur suggestion and am hoping it works. Best wishes.
iOS11
