Users may receive the following error message when launching published applications through NFuse:

“ICA File Not Found”

The following scenarios are known to produce this error message:

The Web pages were presented with the HTTPS protocol and the client cannot 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 client. If the NFuse Web server is using SSL (https://…) and your browser is configured so it does not save encrypted pages to disk, the Launch.ica file cannot be written to disk and the client has no file to open.

To resolve this issue:

A. On the client device, in Internet Explorer, go to Tools > Internet Options.

Select the Advanced tab.

Beneath the Security section of options, clear the option called Do Not save encrypted pages to disk.

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 client.

To resolve this isue, clear the browser cache:

In Internet Explorer select Tools > Internet Options.

Select the General tab.

In the Temporary Internet files section of options, click Delete Files.

Note: You may also want to click Settings to decrease the amount of disk space to use for the Internet cache.

From the MSconfig/General tab, choose selective start option, clear load startup items, and click Apply. Restart the system.

Accessing through NFuse Version 1.6

You can launch applications only once.
