Hello Richard,
                    If those ICs have a transparent window on top, maybe need to be UV erased first.
Check in the top 'Device' tab, and do a blank check first, if it have the window on top of ic, and fail the blank check,
it doesn't  allow you to program/reprogram the device.
If is the case, do an UV erase cicle, to one or more ICs, recheck if pass blank check, and then reprogram it.At bottom left of app window, you can also set  the blank check to run first before programming.
UV light EPROM Eraser Ultraviolet Light Drawer style to erase EPROM micro-controllers erasable IC, Timer can set erasure time (aliexpress.com)
If not the case, post an image with error or what you see.
Hope it helps, or not :-(

    Hello Richard,                         I do not see Admin here for a long time, updates also fail to show,
at least monthly, then i remember that this IC, maybe included in a flaw that appear some
time ago, and maybe not yet corrected. Can you test with older version software?Do not have the IC available myself, then cannot test to see the tip is working or not, sorry.  
You may need to get OS date back to last year or so  12.55 or earlier and be offline, no network?

    Hello Richard,                        As you found a way to program your needed ICs, like me , wait for the new version
of software. Unfortunatly, no new version was out in the latest 3 mounths or so, and also hopping that
this version was not a time bomb date builtin.
To ADMIN, please, release updated software. Thank You :)

Hello Sir,I cannot program the Eprom completely as there are errors in some pages.

Hello Richard,                    Unfortunatly some app software versions ago, many ICs lost writing capabilities,
Do not know if 27011 was affected. You can see it by reports , at least from T48 and T56 Users.
As I've noticed, the problem appear not to be the firmware updates, as users reported going back
some versions back with the software, solve the writing issues on already present ICs in the database.
Unfortunatly, with time passing, many months so far, even the old software versions did not work at
all due to a 'time bomb' included with the software, then date of computer must have rolled back to
get it to work with old versions, even with new software, and disconnected from network.
I also cannot ensure you anything, because i do not have a sample from 27011 myself to test, yet.
In one of the latest presences of Admin here, he said, that they are waiting for ICs to test....
Maybe they are preparing a complete new software ?
I can see they still somehow active, from hardware page at Ali Express Oficial page  XGECU Official Store - Amazing products with exclusive discounts on AliExpress   
as new and cheap adapters appear recently, but thats all.
I've tested many old ICs so far with 12.66, all worked writing except 27Cxxx without glass window
already programed ( OTPs units) , and this behaviour is expected and correct.

I can only hope your sucess with older version software, a new version of software with this error
corrected ( in the case it never worked), and of course, good ICs with You :-)

   Hello,            Nice to hear from you. Do not forget that some old ICs doesn't erase completely with the usual UV time,
then after erase cicle, if they pass test, because they already had the status before erase, you cannot complete
programming (errors). Clean the window as well as you can. Keep posting us with the progress, hoppefully will return to
a montly app update, now at 4 months time.If You can, please describe how you erase it, time , tools used, etc, may help others to find a path to their sucess.

    Dear Richard,                         As you say that new version did not work, can you, please tell us,
as you have a patch to get it to work, as they have included new a D27C011, that use same algoritm
as D27011, which values are shown in the 'others' section at bottom of app window?
for me it shows... the voltages show the same as defaluts on both ICs, normal and 'C' versions.

Yesterday cleaned the label from more then 50 ICs, but still no luck with a 27011 to test :'(

    Hello Richard,                         I guess the problem was only the software needs update, you mention ver 12.68, firmware still the
same as 12.67. As version 12.68 isn't yet available for download, it will soon for sure. Lets wait for it.
I think you made the very best, sending the samples with the programmer.
For worst cases, as many versions/batches available, having samples for test is the best way for quality work, Admin request
this way sometimes in the past.


Thank you for your help and feedback, for sure it will help.

    Hello fordav1,                         Can you, please, post any IC equivalent table or list you may have, or found by your know how,
to help us? Any link to the attached pic adapter suppliers will be nice, also!
