By default, MyOffice Spreadsheet only works with extensions signed with a valid certificate. Invalid extensions are blocked as they are potentially unsafe for the system.

If the selected extension is invalid, a corresponding message is displayed in the Install Extension window. To view detailed information about the error or developer certificate, click Show Details. Click Select Another to select a different extension to install.

If blocking of invalid extensions is disabled by the administrator, such extensions can be installed in the same way as valid extensions.

If the selected extension is valid, the Install Extension window displays the following message: “This extension is ready to be installed. Do you want to continue?” Click Continue.

Invalid extensions are automatically disabled when you install an updated version of MyOffice desktop editors, each time you open MyOffice Spreadsheet and MyOffice Text, and within an hour after the certificate expires. You can enable such extensions manually only if the administrator has disabled the blocking of invalid extensions.

If a valid extension was disabled and is no longer valid during the current application session, when you try to enable it:

•The extension is not enabled.

•A dialog box opens with a detailed description of the reason why the extension cannot be enabled.

•The enable button is disabled.

•A brief description of the reason why the extension cannot be enabled is displayed in the extension line.

The validity of the installed extensions is checked once per hour. The time of the last check can be seen at the bottom of the Extension manager window.

MyOffice Spreadsheet monitors the expiration dates of the certificates of installed extensions. 14 days before the expiration date, a banner will appear with a notification and information about the extension expiration. For more details, click Extension manager on the banner.

You can manually disable and enable the installed extensions.
