  1. Ensure your browser is configured for Blackbaud Hosting Services.
  2. When clicking your application icon, you may receive a security notice that may automatically minimize itself to your task bar or may land behind the browser window. The application will not complete its launching until this item has been affirmed. Please click OK to this prompt to resume the launching process. 
  3. Disconnect from any current open sessions in the Citrix Connection Center.
  4. Clear your Internet browser's temporary Internet files:
  5. Turn off proxy server settings in the browser:

  1. Log into your Application Hosting Portal for Boston or Orange County.
  2. At the top of the screen click Settings.

If the .ica Citrix loader file becomes incorrectly associated with the wrong application, follow these steps to correctly associate it:

1.  Citrix Connection Manager is wfcrun32.exe.  To find its location, search the computer (Start button, then search box against the Local drive) and find the folder it is sitting in.  Make note of this path.
2.  In Control Panel > Default Programs > Set Associations, highlight ".ica".  If the "Current Default" column shows something other than "Citrix Connection Manager", then click the "Change program..." button:

3.  If the Citrix Connection Manager app is not listed in "Recommended Programs" (see screenshot below), then it needs to be associated manually, by locating the executable.  Click "Browse":

4.  Enter the path in Step #1.  Highlight and select the wfcrun32.exe file and click "Open".  Then click OK to get out of the Associations dialog box.

That file type will now be associated with Citrix going forward.
