User installation permissions

Installing MiCollab Client requires administrator permissions on the user’s computer. In Windows 8/10, the user is prompted to provide User Account Control credentials (standard user) or confirmation (administrator) to install the client. Running the client does not require administrative privileges.

All data files that are modified (logs, config, contact database, recorded calls, etc.) when settings are updated (call forwarding profile, startup mode, etc.) are located in the following folder:

  • Windows 8 & Windows 10: C:\Users\{USER}\AppData\Roaming\Mitel\UC

Client firewalls

A client computer that uses a firewall, such as Windows Firewall or a third-party firewall, must specify MiCollab Client.exe and UCASoftphoneManager.exe as exceptions in the firewall's configuration settings. This allows UCA.exe and UCASoftphoneManager.exe to accept network traffic through the firewall. The MiCollab Client client installer adds these exceptions automatically.

Microsoft.NET framework

The MiCollab Windows Desktop Client requires the installation of the Microsoft.NET Framework prior to installing the MiCollab Windows Desktop Client.

After the user installs the .NET framework, he or she will need to restart the MiCollab Windows Desktop Client installation. You can download the Microsoft.NET Framework v4.5 from the Microsoft Web site (
