KB4055532 Security and Quality Rollup for .NET Framework in Windows 7

Update Saturday morning: I did a normal shutdown from Safe Mode last night, not seeing the reply in this forum (thank you, Nasty7). I figured I'd try using the "windows repair" program from my hard drive in the morning. But, this morning, I decided to try one more time and so I did a normal boot up and it worked perfectly! My regular desktop was back and everything seems to be ok. The restore point had rolled me back to the time immediately prior to the install of the windows update yesterday. Of course, a few minutes after I logged on, that update was back, begging to be installed. I "hid" it and will be careful about uploading any new windows updates until I can research whether or not they are causing problems.

Connie, look at Post#8 by Sky Ranch to see manually if you have the prerequisites.
KB4055532 Security and Quality Rollup for .NET Framework in Windows 7 - Windows 7 Help Forums

You can open File Explorer, go to C: Drive>Windows\System32 and browse way down below all the Folders, in alphabetical order, to d3dcompiler_47.dll, to see if it is there.

You can also look in your Updates to see if you have been installing .NET 4.7 installations. They will look something like this, this is the last one I got, before the offending one that may have caused you problems.

Code:

2017-09 Security and Quality Rollup for .NET Framework 3.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7 on Windows 7 and Server 2008 R2 for x64 (KB4041083) Installation date: ‎9/‎15/‎2017 12:09 AM

Thank you, TPau - that picture allowed me to find the d3d compiler in a few seconds. I do have this compiler, the final '47' version, so I went ahead and installed this '532' update. It installed with no problem and I switched off and logged on again just to make sure and all is OK.

Many thanks to all for the help.

Another update on my situation: After my post saying everything was back to normal after I'd used system restore to roll back to the point before the lasted .NET update, I had more (different) problems.

When I tried to start my computer later that same day, the start-up process hung up on the "Wecome" screen. I waited and waited and finally used the power button to shut it down. I tried to start in Safe Mode with Networking but the exact same hang up happened there, too. Used the power button to shut down, and did successfully start up in plain Safe Mode. Tried various things, including rolling back to an even earlier restore point (before the huge update on 1/16) eventually using the F8 key to get to the "Startup Repair" option. Ran that twice, both times it said the OS was starting without problem. So, I restarted normally and again got hung up on the Welcome screen. I walked away and watched some TV. When I came back about 40 minutes later, there was my desktop! I have not shut the computer down since. I just let it sleep and it's working fine. But, I know this is only temporary because eventually I will have to shut down and restart. Plus, if there is a vulnerability, I need to fix it.

This morning, I examined two things per Nasty7's suggestion:

(1) Windows Update history. I have been installing the usual "2017-xx Security and Quality Rollup for .NET Framework..." updates monthly, last one being mid-December, 2017.
(2) I have the "d3dcompiler_47.dll" file installed, but it's dated April 2017.

I've seen some things which indicate what my antivirus company is doing matters. I use WebRoot and they say their next version will include an automatic change to the regkey to allow the windows update and they also provide now a manual way to do that immediately. Do you think I should wait for them, or do it manually? Or, in theory, do I not have to do that because I have a '47' file installed already? I'm just not that knowledgeable about this stuff and have become more confused. So, I appreciate your patience.

Also, are these windows update fixes different from getting fixes from the computer manufacturer for the actual flaws in the chips? I saw what looked like very complicated instructions from another site to fix the chips themselves. HELP!

ConnieB, first off, I'm not the least bit worried about this security problem, at least anytime soon, so don't get into a rush a make things worse, believe me I've done that before. And Webroot has not released a date for this fix, though as you said there is a tool they provide to do it manually.

When you do a System Restore, make sure you Update all your programs before you shut down just to be safe. I think sometimes these out of date programs cause problems after a System Restore.

I would back up all my files before you have more issues, if that's possible. You can do this with an inexpensive USB Flash Drive. This way if you have a major problem you won't have to go to the local repair shop to retrieve your files, and then you could reinstall yourself if you are capable of something like that.

Unfortunately we don't know how good of shape your pc is in now? Have you created Recovery Media? I would get a few of these things done before you shutdown again. Finding Recovery Media for Windows 7 is not easy, unless you buy it from your pc manufacturer.

I would at least manually check the Webroot daily to see if they pushed an update, if not multiple times a day. Or use the Tool They provided. And Update all you Programs. Webroot may have a program Updater Checker, if not someone may suggest one.

You could also Set Windows 7 Updates to Not Check for Updates at all for now. I use "Check for Updates but let me decide whether to download and Install" Setting myself.

It seems to me the "d3dcompiler_47.dll" is just a prerequisite to the latest MS Update, and the "ALLOW REGKEY" registry key is different.

Nasty7, Thank you for the detailed ideas.

--- From what I had been reading, it seemed to me this was not an urgent matter, which is why I hadn't taken any action. I didn't anticipate it would be forced on me. But, I agree, I am trying to act slowly. ---

---Yes, I do have an external back-up drive and the first thing I did when I originally thought my problem was solved was bring that up-to-date, and I will re-do whenever I create new important files (like taxes, ha ha).---

--- Yes, I did that but found the setting changed with all the fooling around I was doing. It actually had re-downloaded, but not installed, the latest big updates. I discovered I could "hide" even already downloaded updates. Now they are listed, unchecked, in the "optional" updates. (I did re-install the Windows Defender update.) I am checking my settings daily to make sure they stay to "notify, but not download." ---

Hello Nasty7,

If you get KB4055532 via Windows Update, then you should install it. Otherwise, you don't need to worry about it.

OMG Nice way to bury the lead - I read that whole thing, as I was reading I was checking my puter for updates and check again for another update KB (whatever #), did a search for .dll file - OK - I think I'm OK, I think I understand

I didn't realize there was a Readers Digest Condensed Version - I wish you had posted this FIRST -
