Compile error with 12F752 ADC to DAC

Hello, I'm new to this forum. My name is Rene. I still get the following error message:

Hi Rene,
Welcome to the forums.
If you make a backup copy of 12F752.fcdx and replace with attached version in:
64bit windows
C:\Program Files (x86)\Flowcode 7\FCD\PIC\
32bit windows
C:\Program Files\Flowcode 7\FCD\PIC\

Finally Reload:

Hopefully you will get further.
You will need to bear in mind that I don't know anything about 12F752 especially it's DAC.

Can you let me know how you get on.

I still get the same problem unfortunately.

I still get the same problem unfortunately.

I compiled using the modified 12F752.fcdx:

After file replaced, did you reload the flowchart:

Can you take a screen shot showing the modified file with the path including time stamp please.

Thankyou!! It working now with the "Reload"option.

You're welcome.
Thanks for the update.
I had added additional Reload instruction in my first Reply.

I can't guarantee hardware will work.
You will need to disable Watchdog timer and possibly MCLR Pin depending on hardware set up.
Also as you're using internal oscillator you will need to add C code to the start of Main with OSCCON value.
See this post

Before trying D to A converter, you will be best dong one second flasher test
Just to make sure hardware is running at the correct speed.
