LogMeIn Windows7 Pro Constant Crashing

Been running LogMeIn Pro for several years on approx many mahcines. Been very happy with LogMeIn and love the product line. We have had almost no issues, until recently. On all of our Win7 Pro machines, LogMeIn crashes constantly upon connection. Once connected it is fine, unless you switch between RemoteControl and FileViewer, etc... The logs (both LogMeIn and Windows EventLog) indicate the issue is within ntdll.dll. LogMeIn support helped up to that point and then offered no futher assitance. this is happening on fresh clean Windows 7 Pro installs on new Dell computers. It does restart after about 2 minutes and 1/3 of the time we can connect, the other times it crashes again. Eventually we can get onto the machine, but sometimes that's after 5 minutes - and we only connect when there is problem that needs attention immediately - so this is a major problem.

LogMeIn support basically pointed us to a google search telling people how to deal with ntdll.dll issues. Since it is running new hardware, with new windows builds, and on several machines, all crashing, it is not likely that is it a hardware probelm - though I admit it could be some kind of driver issue. We've tried disabling everything from Aero, Sound (removed the sound drvivers, driver sharing, graphics acceltation, etc...)

I searched the web and could not find that many references to LogMeIn and ntdll.dll. Is anyone else experiencing this?

Thank you for the response (sorry for the delay in my response, was away on vacation).

We have already tried the client app as well as all browsers we can think of. The host application itself is calling something within ntdll.dll and that is causing the crash.

I am not an expert and am not sure how you're accessing LogMeIn. The issues I had (Win7 Pro OS) - was using IE. Didn’t matter which version 11, 10, 9 whatever, and even had issues with Chrome as a browser. I finally ended up getting the info I pasted below:

I pasted the email reply below that I got from them (LMI). It includes the link to their download page for various products. Please let me know if you have problems. I hope it works for you as well as it has for me.

This is happening due to a security misconfiguration in Internet Explorer. For some reason Internet Explorer is telling our website that it will not allow it to use full functionality due to some security setting. However it isn't the same security settings for everyone causing this. Some have seen this get fixed by restoring Internet Explorer to defaults. Others use a different web browser altogether to get around it, using Firefox or Chrome for instance.

The one sure-fire way to get access to your computers is this, so then let's try a different approach: download and install the LogMeIn Client desktop app for Windows which you can find on the left side of this page:http://help.logmein.com/SelfServiceDownloads and try accessing through that application. This is a fully functional replacement of the procedure of logging in through the website this will bypass the issues that some web browsers may have.
