  • ISAPI Extension cannot write temp files

    Mar 10, 2019 03:05 AM|RolandSmith|LINK

    I have two Windows 10 Home computers. On my laptop I developed an ISAPI Extension (in regular C) which among other things writes data to a temp file.

    Everything works fine on the laptop. In fact it worked the first time. Now I am trying to get it setup on the other computer and the file write feature isn't working.

    I have a custom Application Pool using ApplicationPoolIdentity. I have tried writing the file to several different locations and have given permissions to IUSR but I still can't write the file. I've tried the system temp folder, C:\Temp, and others.
