The application is probably running with "Internet Guest Account" privileges, which do not have write access to Windows' TEMP folder by default. — Havenard, May 10 '11 at 07:55
Problem solved when I gave "CREATOR OWNER" group, Full access to this folder! — Sali Hoo, May 16 '11 at 16:27

Here are the steps to fix it:

Go to C:\Windows

Right Click the Temp folder

Click on Properties

Go to Security

Give CREATOR OWNER group full control.

+1 But note that windows might ignore the permission changes, the best way around that is to change (temporarily) the ownership to the "Creator Owner" group and then give it full permissions (note that changing ownership to the current logged-in user doesn't necessarily help) – yoel halb Jun 12 '12 at 22:01

I tried to give full rights to Creater owner but it always changes when i click apply.So later what i have done is right click temp folder and then click "Take ownership". – Kamran Shahid Nov 25 '12 at 08:26

for those who cant give FULL CONTROL to c:\windows\temp like me

[this is how i solved]
1- run cmd AS admin (keep it open ).
2- open task manager and KİLL explorer.exe.
3- goto previously opened cmd. write explorer.exe hit enter.
4- go to c:\windows temp (right click)>properties ->security
5- now you will be able to change \IIS_IUSRS to Full Control

note: some application may give error about elevated exploer.exe . it will be fixed after restart.

if you dont wanna restart;
[take explorer.exe out of Administrator mode]
1- goto previosly opened task manager. kill explorer.exe
2- in task manager file-> start new process write there explorer.exe
3- now the explorer.exe is in normal mode.

Tnaks a lot. Allthough it looks like a Windows security issue, it solved my problem. — Manfred Wippel, May 09 '19 at 17:42
