I DID ALL The Below Steps

1. Open Windows Explorer

2. Depending on whether you installed a 32bit or 64bit version of office you will need to do one (or both) of the following: 32bit Office installation: Navigate to C:\\Windows\\System32\\config\\systemprofile 64bit Office installation:

3. Navigate to C:\\Windows\\SysWOW64\\config\\systemprofile

4. Verify the folder "Desktop" exists (create it if it's not there)

5. Right click > Properties

6. On the security tab: Add the account under which the site is running (eg: Network Service) with default permissions (Read & execute; List folder contents; Read)

In the dcomconfig utility,

go to Component Services --> Computers --> My Computer --> DCom Config --> Microsoft Excel Application (and Powerpoint)

Right click it and go to properties. Go to security tab. Under Security

1, Launch & Activation Permissions --> Choose customise and click Edit. Add User Network Service and check everything under Allow for it.

2. Do the same for Access Permissions and Configuration Permissions.

Then click Apply and close everything.

Sometimes I can download the file but sometimes I got this error Any ideas why?

I did method 4 and it worked for me: https://support.microsoft.com/en-gb/kb/2758592

Method 4: Investigate possible issues with COM add-ins

Many developers create add-ins for Excel. These add-ins are divided into two types: Excel add-ins that are saved as .xla, .xlam, or .xll files. COM add-ins. These add-ins usually have to be installed and include DLLs and registry keys. COM add-ins created for one version of Excel frequently are not compatible with a newer version, and may cause crashes. They are not disabled by Safe mode, and should be investigated separately.

To disable COM add-ins, follow these steps: Select File > Options > Add-ins. At the bottom of the dialog box, change the Manage dropdown to COM add-ins, and select Go. Clear the checkbox for any enabled COM add-ins. select OK. If disabling the COM add-ins alleviates the issue, try enabling them one at a time to test for the problem add-in.If these steps do not resolve your issue, continue to method 5.
