Install Boot Loop

[HaroldW]

Howdy,

Every time I install, it says it needs to reboot to complete, after reboot, it tries to install, says it needs to reboot to complete, etc.

I read through: 

 

and I don't have the registry keys for:

1.  HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Malwarebytes Anti-Malware_is1

2. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{35065F43-4BB2-439A-BFF7-0F1014F2E0CD}_is1

Attached are my results from Check, Clean, and FRST.

Thanks,
Harold

Hello @HaroldW

Can you please try this:

1. Download the mbam_clean tool from: xxx

2. Run the tool. Tool will ask you for a reboot.

3. After reboot please run the latest MB 3.3.1 build from https://downloads.malwarebytes.com/file/mb3

Let us know if that worked.

The following MBST tool should be used to perform a clean removal and reinstall

Downloaded the latest clean file, ran it, rebooted.

After reboot, downloaded the 3.3.1 build, ran it, it started up and then said it needed to reboot to complete installation.

Rebooted, after reboot it automatically restarted the setup.  Click Agree, and then it says my computer must be restarted to complete the installation again.

Still stuck in the reboot loop.

Just to confirm @HaroldW did you run mb_clean or mbam_clean  ?

[HaroldW]

mbam-clean-2.3.0.1001.exe

Hello @HaroldW

Can you please try something just to rule out an infection.

Can you boot into safe mode and run the latest installer and check if its doing the same thing (asking for a reboot)

[HaroldW]

Sorry for the delay, I had to go out to the customer site.  I booted into safe mode, no networking.  Ran the MB3-Setup-Consumer-3.3.1.2183.exe and it said it would need to reboot to complete setup.

Rebooted back to safe mode, run setup, and it's back in the boot loop.

Boot back to normal mode, setup tries to continue to run but it's also back in the boot loop.

Same situation.

Thanks,
Harold

Hi @HaroldW

Can you please do this:

2. Export that registry key.

3. Please attach it to the post here.

Thank you.

Here's the key.

Can you please try this:

1. Delete this registry key: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{72BE25D7-574A-4F4D-B9B3-907D239CE1C7}

2. After you delete this key run the latest installer from https://downloads.malwarebytes.com/file/mb3

Let me know if that worked.
