Error: Invalid temp directory in Chart Handler Configuration
#1 · November 27, 2025, 8:06 am
After installation, in the home page you sometimes get this error:
Error: Invalid temp directory in Chart Handler Configuration [c:\TempImageFiles]
This can happen because of various reasons:
- The temporary chart folder is not accessible
- There are multiple installation of OfficeClip on the same machine and the chart folder is locked by one of them
To fix this try one of the following:
- Make sure that the folder is accessible and has adequate permission for ASP.NET user (Network Service user in Windows Server 2003 and higher)
- In the web.config (located at c:\program files\officeclip\8\officeclip for default installation), look for the ChartImageHandler key and try changing it to something like:
<add key="ChartImageHandler" value="storage=file;timeout=20;dir=D:\TEMPDUMP\;"/> and make sure that you have the folder d:\tempdump and it has adequate permission for ASP.Net process to write to this folder.
Note: Always make backup copy of web.config before changing anything.

I have noticed in Windows 7 Professional whatever you do it shows the same error. In that case it is a good idea to create a folder on your C: drive called TempImageFiles at the root level and give full permission to ASP.Net account.
