To work around this problem, verify that the ASPNET account has the correct user rights as follows :

%windir%\Microsoft.NET\Framework\Version\Temporary ASP.NET Files: Full Control
%windir%\Temp: Full Control
Application folder: Read
%installroot% hierarchy (for example, %windir%\Microsoft.Net\Framework\Version): Read
%windir%\Assembly: Read

Note This is the global assembly cache. You cannot directly use Windows Explorer to edit ACLs for this folder. Instead, open a command window, and then run the following command:
Code:
```
cacls %windir%\assembly /e /t /p domain\useraccount:R
```
Alternatively, before you use Windows Explorer, run the following command to unregister Shfusion.dll:
Code:
```
regsvr32–u shfusion.dll
```
After you set user rights in Windows Explorer, run the following command to re-register Shfusion.dll:
Code:
```
regsvr32 shfusion.dll
```
Web site root (for example, %root%\Inetpub\Wwwroot) or the path that the default Web site points to: Read
%windir%\System32: Read
(Typically, the ASPNET account has already been granted user rights as a member of the Users group.)

After a lot of research i found that it might be the problem of .NET Framework in your computer. I will recommend you to install the latest framework to your computer & try. I can say that this will definitely work...!
