IDE 1.8.9, windows 10 update upload issue.

Development Tools Uploading

So I've been working on a project for a while that uses ver 1.8.9 IDE and a Arduino Nano. It was working fine until the a windows 10 update a couple weeks ago. Now, I can't upload from either the win 10 computer or a win 7 computer the board and got the following error...

Arduino: 1.8.9 (Windows Store 1.8.21.0) (Windows 10), Board: "Arduino Nano, ATmega328P"

Sketch uses 930 bytes (3%) of program storage space. Maximum is 30720 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

(couldn't get the code tag to work)

I've tried several boards, several cables, two different machines and to test I am simply trying to upload the blink sketch. Always the same result. One of the computers was Win 10 and the other a Win 7. Both computers had updates applied between the time this worked and then didn't work. I am reasonably sure it is not the Nano, the USB cable, or the the sketch (which compiles fine)

I am pulling my hair out trying to figure this out but I am out of ideas. Can anyone give me some guidance?

Select Tools > Processor > ATmega328P (Old Bootloader) and try uploading again.

Seemed to swap one error for another. After selecting the ATmega328P (Old Bootloader) i get this error.

Build options changed, rebuilding all
Sketch uses 3736 bytes (12%) of program storage space. Maximum is 30720 bytes.
Global variables use 331 bytes (16%) of dynamic memory, leaving 1717 bytes for local variables. Maximum is 2048 bytes.
avrdude: ser_open(): can't open device "\\.\COM5": The system cannot find the file specified.


Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

I've been through the trouble shootiig guide a couple times and any of the issues listed there.

Wow! I didn't see it till now but the com port shifted back to com5 and I am on com19. I really thought I had checked that....

Worked now

thanks
