There is a bug with the latest CC release (Windows) where if I have a specific profile correction applied to a photo it will not export and give me an 'internal math error' warning. The profile is for the Rokinon 12mm f2.8 ED AS NCS Fisheye. If i take profile correction off it exports like normal. Not a cache issue. Not a GPU issue.

Hi TheLandOfDustin,

Sorry that Lightroom Classic is giving an error message "Internal math error" while exporting images with specific profile correction applied.

Could you please restore Lightroom Classic app preferences to default and let us know if the issue still persists? Please refer this article for step by step instructions: https://helpx.adobe.com/lightroom-classic/help/setting-preferences-lightroom.html#restore_preference...

Let us know how it goes.

Thanks,

Akash

this does not work - restorring settings doesn't fix code errors in the software - this is a problem on Adobe's side of things. NOT the end user.

A corrupt preference file  is not a user error or user mistake. And while it may or may not be an coding error by Adobe, or a hardware error, it occurs and is fixable, If this works, cross fingers that it does not show up again.

 

I am sure examples of this problem and resetting the preferences file exist.

 

Here is one:

https://community.adobe.com/t5/lightroom-classic/internal-math-error-when-exporting-as-well-as-blue-...

 

So, why not give it a try.

 

Now a few warnings.

 

1. After you have Lightroom Classic reset the preferences file, or if you manual move/delete the preference file your shelf. When you restart Lightroom, it is possible that the previous catalog might not get launched . No biggie, just open the correct one.

 

2. It is possible (I can not quantify) that your preferences will reset to defaults.

 

3. Remember, resetting the preference file is Adobe speak for replacing the preference file, not for altering preference settings.

 

 

4. Just a by the way, reinstalling LRC does not replace the preference file.
