I had this several times in the past months. For me the root of the problem comes from ccleaner deleting the temporary folder "SDLTempFileRegen".

If this or similar is also the case for you then an easy fix is recreating the folder:-
Go to %temp% and create a folder named "SDLTempFileRegen". You then will be able to save your file again.

Hello Angela,

I am having this problem right now and creating the folder solves it but just temporarily. I mean, I have to create the same folder time and again (for almost every project). It seems that it gets automatically deleted somehow. Does anyone know any solution?

Many thanks,
Helena

Hi Helena Barrio Herrero 

It's the same here: evertime ccleaner runs it deletes the folder. Unfortunatley I can't exclude it.

My solution is a simple .BAT file which creates that folder. For convenience I pinned it to Start.

This is how you can create the .bat file:

• Open Notepad
• Copy / paste in "mkdir %temp%\SDLTempFileRegen" (without quotes)
• Save the file somewhere (eg. as CreateSDLTempFileRegen.bat). You can name it anything but you should leave the .bat extension

When you double click on it in Explorer you might briefly see a Cmd window pop up and vanish. Since it is just 1 command it goes really fast. Anyhow, it should create the SDLTempFileRegen folder. If not then you are most likely missing the path definion of %temp% in your Environment. Then you can either replace %temp% in your .bat file or add it to your paths (https://www.google.com/search?q=add+environment+variable).
