After installing the latest sdk I got at_cmd_parser.h error.

I tried to change the path but didn't work for some reason.

Please copy & paste the error text - not a screenshot.

Also the relevant source line(s).

Probably best to paste the error text as for source code - just leave the 'Language' as 'Text' (ie, omit Step 3):

Hi!

What NCS tag are you on? 

at_cmd_parser.h was moved to ncs/nrf/include/modem a few tags back, so all includes of this file should be #include <modem/at_cmd_parser.h>

Just changing this line won't work, as there are probably a lot of there small changes made. You need to make sure when running an older application, that you run it in the correct NCS tag.

Best regards,

Heidi
