Vmware Vcenter Converter Standalone Unable To Start The Change Tracking Driver Apr 2026

She changed it to "Warn" (temporarily), ran gpupdate /force , rebooted again, and started the conversion.

This time, the driver installed. The progress bar jumped from 5% to 15%.

Same error.

Sarah sighed. Not this again. She opened her browser and started the late-night ritual. The VMware forums were full of similar stories—admins stranded at the same 5% wall. Change tracking. That kernel-level driver used by Converter, Backup APIs, and replication tools to monitor disk block modifications. Without it, no incremental sync, no hot cloning. Just failure. She changed it to "Warn" (temporarily), ran gpupdate

The logs were her only friend now. She navigated to %ALLUSERSPROFILE%\VMware\VMware vCenter Converter Standalone\Logs and opened converter-worker.log .

She had done this a hundred times.

The next conversion attempt was clean. The driver started. The clone synced block by block. Same error

And somewhere in a data center, another Windows box silently stopped breathing, waiting for its own 2 AM hero.

She closed her laptop, leaned back, and stared at the ceiling.

She disabled the AV real-time scanner temporarily. No change. She opened her browser and started the late-night ritual

ERROR: Failed to install change tracking driver. Error 577: Windows cannot verify the digital signature for this driver. A recent hardware or software change might have installed a file that is signed incorrectly or damaged. Error 577. Signature validation failure.

At 5%, the progress bar froze.
