I am running Windows 10 on my home Dell XPS laptop after re-configuring the pc a few days ago following a disk failure. All has been running fine for a few days and I installed MBAM version 3 a couple of days ago and decided to run a scan earlier today. When I tried to open MBAM (for the first time since it was installed) I got an error message that said something like Service error unable to start Malwarebytes Antimalware. I thought I would try to resolve this by uninstalling and re-installing the software and uninstalled using 'Uninstall a Program' but when I tried to re-install I got an error message, as follows:
An error occurred while trying to replace the existing file: DeleteFile failed: code 5 Access is denied
Click Retry to try again, ignore to skip this file (not recommended) or abort to cancel the installation. ‘
So, I aborted the re-install and followed this process:
Navigate to C:\Windows\system32\drivers
Find mbae64.sys, right click and select rename, and change it to mbae64.old
Now try to install new Malwarebytes, it will be installed without any issues
But, when I tried to rename the file in step 2 I got a message that I need administrator permission to rename this file. I was logged on to my system with my user account that has administrator rights so I am not sure what to do.
Please would somebody be able to help me resolve this so I can re-install Malwarrebytes ?
