Installation path cannot be a root directory error

[exile360]

I just tried installing the beta over 3.8.3 and after clicking on the advanced options link in the installer and unchecking the option to create a desktop shortcut and then clicking Install I received the following error:

Here is what the installer looks like where I am clicking 'Install':

I did not change the default install path, I didn't click 'Browse' and all I did was click the checkbox next to Create desktop shortcut to uncheck it so I'm not sure why it's throwing this error, but I thought you might want to know about it.  I'll try a couple of things to see if I can get around it.

I'm on Windows 7 x64.

I finished the install by skipping the advanced options and instead just using the defaults and was prompted to reboot to complete the installation.  After doing so, I noticed that MB did not launch on boot and so I launched it manually only to discover that I was till on version 3, not beta 4.  Obviously there was a problem during the upgrade.

Here is the install log.  I'll try again by removing MB3 first to get the beta installed.

Hello @exile360
We're aware of the bug and this should be fixed in the next MBAM 4 iteration.

Out of curiosity, what version was mbsetup.exe?

It should be saved in C:\ProgramData\Malwarebytes\MBAMService\instlrupdate

I grabbed a fresh copy of the installer front-end for the beta right before initiating the install so it should be the latest one; I didn't upgrade to the beta through the UI of MB3 so there is no instlrupdate folder.

The MBSetup version released to the MB3 beta channel (version 97) contains the fix for this issue. The installer can be downloaded from here: https://malwarebytes.box.com/s/j5v0tn737r3ay1qsc0ggos3tqm2qeq2c

Cool, no worries, I already got it installed, but that explains why I ran into the issue in the first place since I didn't upgrade to the beta through MB3; I just downloaded the web installer for the beta itself and tried installing it over 3.8.3.
