Error: ICA File Not Found

Error: ICA File Not Found

Document number: 28901

Symptom:

User receives an ICA File Not Found error when launching published applications through NFuse.

Cause:

The following scenarios are known to produce the ICA File Not Found error:

Web pages are served with HTTPS and client can not save encrypted pages to disk

When a user clicks an application icon, the launch.ica file is downloaded from the web server and then executed by the local ICA client. If the NFuse web server is using SSL (https://...) and your browser is configured not to save encrypted pages to disk, the launch.ica file can not be written to disk and the ICA client has no file to open.

Excessive internet cache

On Windows computers with large hard drives, the Temporary Internet Files folder used by Internet Explorer can become excessively large, causing too much of a delay in the time required to save the launch.ica file and then retrieve it for use by the ICA client.

Resolution:

Configure your browser to save encrypted pages:

In Internet Explorer select the Tools menu, then select Internet Options.
Select the Advanced tab.
Under the Security section, uncheck Do Not save encrypted pages to disk.

Clear the browser cache:

In Internet Explorer select the Tools menu, then select Internet Options.
Select the General tab.
In the Temporary Internet files section, click the Delete Files button.
You may also want to click the Settings button to decrease the amount of disk space to use for the Internet cache.
Clear any copies of the launch.ica from the local drive, then re-launch Internet Explorer.
