Let's see if we can square this away:
So if I downloaded 1.3.15 then why does it show the same version number as before? I'm stymied at this point and do not want to move on to Step 4 (Session Manager) until we resolve this conundrum.
Not quite sure what to make of that myself! That may be a question for the maker of XMarks. Atleast you know you have a clean and fresh version, as updated as we know it to be.
Go ahead and reinstall Session Manager.
I have also noticed that for some time that Tools/Reopen last browsing session has been grayed out. I don't remember if that started before or after my original posting. I was accustomed to using it because the selection to restore the previous browsing session in IE options never did work.
That could be a result of repairs. History was erased in both of the FRST fixes. After that, a new history will have had to be rebuilt in order for Reopen last browsing session tabs to open as such.
To check further with regard to Reopen last browsing session not working correctly, please check the following settings:
Press Windows Key + R combination and put inetcpl.cpl and hit Enter to open Internet Properties.
In the below window, make sure you have selected the option Start with the tabs from last session under Startup.
After making this setting, whenever you open Internet Explorer, it should start from last session tabs, or simply it will restore the tabs. If that is already checked or if Internet Explorer on your system is not able to restore tabs after making this setting, try this:
1. Press Windows Key + R combination and put inetcpl.cpl and hit Enter to open Internet Properties.
2. In the Internet Properties window, switch to Advanced tab first. Then here in Settings section, scroll down to find Enable automatic crash recovery* option with a star mark on it. Star mark shows whatever changes you make to this setting, it will be effective after reboot.
Since you’ve mentioned the issue of not restoring the tabs, you might find this option unchecked.
If not checked Check this option and click Apply followed by OK.
Reboot the machine and start Internet Explorer, you should be able to restore previous session if you have not deleted browsing history of that session.
Let's check the system files, make sure they are ok:
Please close all windows before proceeding.
Press Windows Key + R combination.
In the Open field, type sfc /scannow (Note: There is a space between sfc and /scannow)
Select the OK button.
Follow the prompts throughout the System File Checker process.
Reboot the computer when System File Checker completes.
Please let me know how it goes
