Do the following to verify that iManage Drive is properly installed on your device:
Application installation
After running the application installer successfully and quitting the installer wizard, verify that the iManage Drive 
icon is displayed in the Windows taskbar.
Folder mapping
Go to the network drive, which is M drive by default in Windows.
NOTE:
If the M drive is already in use, the mapping isn't created. You can set it to any other drive letter using the native_drive_letter option. For more information, refer to Configuring user settings and Changing iManage Drive directories.
Ensure that the workspaces you synced are available.
Verify that the workspaces contain the same folders and files that are available in iManage Work.
Application integration
Right-click any file on your local drive and verify that the context menu options are available.
