Thank you very nuch bob3160, ondrejz and Asyn !!!
It did work !!! (running compatibility with Windows 2000, since I tried first with Windows XP SP3, which was the default selection, and nothing changed). Greetings from Spain.
You’re welcome and thanks for the feedback.
Yeah, it worked.
However, Bank Mode shows grey window when its starts, and doesnt show any tabs and then it becomes not responding.
Additional in event log Win 7 there are errors related to Avast Secure Browser Elevation Service.
The problem, alas, is not solved.
The problem with elevation service in system log will be solved too. We know about it. This is a minor issue now - it does not block you in anything.
The bank mode is problem because you cannot change how the browser in bank mode is started 
The only solution will be update to next version.
I haven’t been able to use the browser since about April the 20th either. I tried turning off hardware acceleration, and I really have no idea what the ramifications of messing around in there are… as I started the nVidia program that runs my video card because windross 7 wouldn’t let me disable hardware acceleration from the control panel. I had to first add avast secure browser to the list of software it (nVidia) was supporting, then I tried to turn off hardware acceleration, but instead had to turn off about 10 options individually (oh, that program they made really sucks), some of which couldn’t be turned off…
That didn’t work…
Oh, and, I BARELY stumbled through the process (using computers for 20+ years), I have NO IDEA how my mother could do this… oh, wait, it would have been IMPOSSIBLE… Welcome to the “world of computers, 2019”, STILL unusable by the average person!!!
Anyway, what you recommended worked (I tried windross 7 first, that was a no-go).
Ok, you tried 2 ways, I went straight to windross 2000 and it worked… but, really? I’m supposed to use this in windross 2,000 mode?
So, if I reinstall Avast Secure Browser, I’ll lose the history and various other things in there, right? Of what value is that, if it’s unreliable? There are IMPORTANT things in there.
Can I reinstall without losing the passwords, bookmarks and a few other things in there, or not?
Thank you evallejo, because until I saw that I should choose windross 2,000, well, I don’t know, I was digging through some unforesaken parts of windohs’ twisted tangled options sub-sections and bumped into it.
Starting a program that won’t start to change an option setting wasn’t doing it for me.
I haven’t updated wingross 7 for about 8 months, could that have anything to do with it?
I have NO PROBLEM with Mozilla FireFox, Google Chrome, Opera and Vivaldi of which I run all of them at the same time, even until Avast Secure Browser failed on me. I quit all of those browsers including ASB to re-boot my computer which had been running for about 8 days, and all except ASB would start back up again.

Hi Asyn,
Can I install it over the current one that is there, WITHOUT losing my history file, and the various places I have logins at and, the bookmarks, etc.?
Hi, should work.
Hi,
I’ve had this problem too since version 73… Windows 7 sp1 x64 and x86 machines.
Installing NET Framework 4.7.2 (kb4054530) solved the problem!
Hope this helps.

I have this version of the .NET Framework already installed and it makes no difference.
Not a problem on Windows 10. Wonder if it’s Windows 7 related ???
I have this version of the .NET Framework already installed and it makes no difference.I was able to launch avast secure browser after installing this version of net framework (included in windows 10 by default, I read). Just a thought : do you install windows updates? Nicolastr
I have every single Windows 7 update installed. I am very anal about making sure to keep my machine with the latest stuff.
No clues.
Have you had this problem since secure browser version 73?
Version 74 is available download it from here: https://www.avast.com/en-us/secure-browser
The website still states 73 but the download is version 74.
On my windows 7 machines, secure browser v73 didn’t work. When I updated to v74, it still didn’t work.
After installing net framework 4.7.2, secure browser v74 launches.
The browser works fine on my machine. It all the errors that are getting written to my System log that is my problem. Something about Elevation Service and Schannel errors.
getting the same issue, using windows 7
If its helpful, it really seems like everything is there in the browser, but for some reason its invisible. Like you can type stuff into the address bar if you can find and click it (though the text is invisible too)
I also clicked and dragged in the middle of it and could see a pic I clicked on that was in the browser.
