"ICA File Not Found"

Home > Troubleshooting > ICA File Not found

Symptoms

This symptom occurs on a Windows Computer in Microsoft Internet Explorer.

1. User gets to the login page
2. User clicks the TSSM icon
3. An "ICA file not found" error is displayed. Only choice is OK and then nothing happens.

Resolution

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

1. 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.
   
   To resolve this issue, at the client machine:
   1. In Internet Explorer select go Tools > Internet Options
   2. Select the Advanced tab
   3. Beneath the Security section of options, uncheck the option called Do Not save encrypted pages to disk
2. 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.
   
   To resolve this issue, clear the browser cache:
   1. In Internet Explorer select go Tools > Internet Options
   2. Select the General tab
   3. In the Temporary Internet files section of options, click the Delete Files button.
   4. You may also want to click the Settings button to decrease the amount of disk space to use for the Internet cache.
