Solved: Internet Explorer Flashes Open Then Immediately Closes

Posted by admin on June 28, 2011

I was updating another browser on my Windows 7 system and all of a sudden IE 9 decided it didn't want to start up anymore. After a day of bad advice from Microsoft's tech forums I finally found the working solution:

Re-register IEPROXY.DLL by clicking START  (the win 7 icon in the bottom left hand corner of your desktop) and typing 

regsvr32.exe "c:\program files\internet explorer\ieproxy.dll" 

and then clicking OK.

If it doesn't find ieproxy.dll, dig around your system to find its location.

That simple. Add it to your tech boards, Bill

I just ran across this on a Win7 enterprise machine and I had spent 90 minutes trying everything and this fix worked.

Muchas gracias por el tip, es el único que realmente me funcionó.

Es increíble cuantas soluciones inútiles ofrecen en las páginas oficiales de Micro$oft.

Ya son demasiadas las ocaciones en que la solución de algún problema, la encuentro en cualquier otro lado, menos en las páginas oficiales donde supuestamente deverían estar.

Something as simple as this after about an hour searching for a fix from microsoft and they NEVER list this in their list of fix its. Thank you! I used this method posted by another commenter:

"run command prompt (cm) as an administrator click start, and type cmd then right click and click run as administrator then copy the above and paste in..."

Tried but did not fix. Windows 7-64 IE8 uninstalled 9 and 10.

IE in 2 places Program files and Program Files (x86)ieproxy.dll Modified ?Thursday, ?December ?20, ?2012, ??8:55:20; AM Accessed Yesterday, ?March ?09, ?2013, ??11:06:16 AM and? Modified Thursday, ?December ?20, ?2012, ??7:49:52 AM Accessed ?Yesterday, ?March ?09, ?2013, ??11:06:16 AM.

IE worked when Chrome uninstalled and brought up "sorry page" that is what I'm currently using.

Great tip. Though on a 64-bit machine you have to run the command twice.
Once as above: regsvr32.exe "c:\program files\internet explorer\ieproxy.dll" and then again: regsvr32.exe "c:\program files\internet explorer (x86)\ieproxy.dll"

Didn't work for me. running IE 10 on Win 7 Professional 64 bit. Only IE 8 seems to run even if they Administrator rights. When logged on the actual Administrator account, IE 10 works fine. I'm baffled. I will have to roll it back to IE 8 in order to get functionality.

didn't help.. this is IE10 though

There needs to be a slight change for the 64-bit instructions. The (x86) bit was in the wrong place. The second line should be:

regsvr32.exe "c:\program files (x86)\internet explorer\ieproxy.dll"

It's now working for me.

I executed both commands and it did not fix the problem. When I click on the ie symbol the screen still flashes and ie does not start up. Oddly enough, when I try to run IE form either the program files or the program files (x86) directory I get an error message

I finally got it working. I used the commands above but use F: instead of C:. I found folders on f: from before my re-install of windows on c: somehow the system trsy IE icon was pinting to F:

Thanks Gabe, your regsvr32.exe "c:\program files (x86)\internet explorer\ieproxy.dll" did it for me. :)

On Win 7 64 bit regsvr32.exe "c:\program files (x86)\internet explorer\ieproxy.dll" worked for me too.

Thanks again!!

I have been trying to get IE 10 installed on my local pc for the longest time and this fix finally worked for me. THANKS!!!!

Brilliant! Worked for me with IE 11. Microsoft support is useless, tried everything they suggest nothing worked until I stumbled on this solution. Wasted a few hours in between... Many thanks

I tried the regsvr command but get an error msg that The Module failed to load. IE is useless. It just will not load. flashes then disappears. I have tried just about everything.

For those of you who have 2 partitions and may redirected the default installation path to the second partition, you will need to register the dll on the secondary drive. IE does not install onto the default Windows Directory.

Thank you to the original poster of this fix!

(for those with dll issues after running the fix enter the command: sfc /scannow and run this fix afterwards)

THANKS! also for x64 run this after the first one.. that bit took me awhile to figure out since the OP obviously is on a 32 bit os

regsvr32.exe "C:\Program Files (x86)\Internet Explorer\ieproxy.dll"

This worked for me too, thank you
