Viewed 293 times


This article describes a scenario in which a ZCA VRA continuously crashes due to some files being installed on C: drive when Zerto is installed on a different drive letter.

Root Cause

The ZCA was not installed in the default drive and location: "C:\Program Files\Zerto\Zerto Virtual Replication"
Dependent files gets created on the C: drive and in the default location and if Zerto is installed on a different drive or location, it will not properly reference these dependent files.


  • ZVR is installed on a different drive than the C: drive
  • ZVM may report a disconnection with the VRA
  • VRA service not stay running and ZVM may report as crashed
  • The following assert is also found in VRA logs similar to the following:

Copy the files from the "C:\Program Files\Zerto\Zerto Virtual Replication" to the current drive and location of the Zerto installation.

xcopy /E "C:\Program Files\Zerto\Zerto Virtual Replication" "D:\Program Files\Zerto\Zerto Virtual Replication"

Permanent fix:
Upgrade to Zerto version 8.5 or higher
