The silent installation enables an administrative install of the Outlook plugin as a company-standard application. The process allows an IT admin to obtain a Trusted Publisher certificate for the plugin and deploy the certificate to user machines, and to create an installation package that will automatically install the plugin on user devices. The certificate must be renewed on an annual basis.
Once the plug-in is installed on a user's account, it updates automatically. Each time Outlook is restarted, the plug-in checks for updates, and if they are available, makes the updates automatically without user notification.
* Required for Outlook 2016 and later only
Deploying the certificate(s) consists of copying the file or files to local machine stores and then adding them to the Trusted Publishers store for both the machine and the current machine user. Most IT departments have tools that accomplish these steps. The deployment of the certificate(s) is described here as a separate step, but you could also incorporate it into the silent install described in the next section.
To test this, or if you are scripting this install, you could use a script with syntax something like the following (the script will pick up all certificates in the directory):
@Certutil -addstore -enterprise -f "TrustedPublisher" LogMeIn*.cer"
If you want to step through these processes manually to test them or for a problem machine, see Install the Trusted Publisher Certificate Manually.
The silent mode installation of the GoToMeeting Outlook Plugin can be accomplished using your standard IT deployment tools. LogMeIn provides an installation package that includes sample scripts and the Plugin installer that you can use or modify as needed.
The scripts provided, and their functions, are:
|ImportCertificate.cmd||Copies the certificate to the local machine and adds it to the Trusted Publishers store for the machine and current user.|
|Test_SilentPluginInstallation.cmd||Sample install of the GoToMeeting Outlook Plugin.|
|TestandInstall_G2MOutlookPlugin.cmd||Sample boot script to check for the plugin, and if it is absent, to install it. Also disables existing, older version of the plugin.|
|TestandInstall_G2MOutlookPlugin.ps1||The sample boot script in Windows PowerShell format.|
|LogMeIn_2015-2018||The certificate file.|
1. Click Download to get the certificates.
2. Click Download to get the install package.
The contents of the package are:
- ImportCertificate.cmd - this picks up a qualified certificate files in the directory location
3. Create the install model that works for your environments. The full install should accomplish the following:
- Execute ImportCertificate.cmd as administrator to copy and install the certificate(s).
- Optionally check local machines on boot for the presence of the plugin using the equivalent of TestandInstall_G2MOutlookPlugin.cmd.
- Install the plugin in silent mode as in Test_SilentPluginInstallation.cmd, or TestandInstall_G2MOutlookPlugin.cmd.
- Disable any older plugins.
If you are using a boot script on local machines, the syntax would be something like:
"C:\Program Files (x86)\Common Files\microsoft shared\VSTO\10.0\VSTOInstaller.exe" /install https://builds.citrixonlinecdn.com/builds/calendarintegration/ outlook/G2M/GoToMeetingOutlookCalendarPlugin.vsto /silent
This completes the silent mode installation instructions. If you have difficulties, questions, or comments, please either comment on this page, or contact email@example.com.
The remaining sections of this article provide manual steps for the certificate deployment process.
If there is a problem installing the Trusted Publisher certificate, or if the install is to be performed locally on a user device, you can complete installation manually.
1. Locate the LogMeIn Signing Certificate, for example LogMeIn_2015-2018, and double-click on the file to check the expiration date. The certificate is valid for roughly one year. Note the date of expiration and set a reminder to download a new silent install package with a new certificate a month or so prior to the expiration of your current certificate.
2. If the certificate is valid, click Install Certificate. Choose Next to continue.
3. In the Certificate Store window, choose Place all certificates, and click Browse. In the Select certificate store dialog, select Trusted Publishers and click OK, then click Next.
4. In the Completing the Certificate Import window, make sure the Certificate Store Selected by User is selected, and choose Finish.
5. After a few moments, you should see an "Import was successful" dialog box. Choose OK to end the install process.
1. In your computer's Start menu, type mmc in Search programs and files and press Enter.
2. If you are asked for permission to proceed choose Yes. The management console opens.
3. Open File | Add/Remove Snap-in.
4. In the Add/Remove Snap-in box, select Certificates and then click Add.
5. Click Computer Account, and then click Next.
6. Click the Local computer (the computer this console is running on) option, and then click Finish.
7. Repeat steps 4 and 5, this time choosing My User Account.
8. Click Close, and then click OK. If you are asked to Save the console settings, choose Yes.
