Fix for “Internet explorer has closed this webpage to help protect your computer”
Many users face issue running Oracle forms on Microsoft Internet Explorer 8 (IE8) which causes the page to redirect to following url
res://ieframe.dll/acr_depnx_error.htm#<domain>,http://<server>:<port>/forms/frmservlet?config=<config>
It displays following error.
Internet explorer has closed this webpage to help protect your computer
A malfunctioning or malicious add-on has caused Internet Explorer to close this webpage.
Solution:
Goto Internet Explorer -> Tools -> Internet Options -> Advanced -> Scroll down to Security -> Uncheck “Enable memory protection to help mitigate online attacks*”
Close all browser windows and restart the browser. The issue should have been fixed 
Edit: Alternatively you can use either of following 2 alternate solutions.
Alternate 2:
Open registry using start->Run->regedit->ok
Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main
On the right hand side you will see a DWORD key called DEPOff. IF this is set to value 0, just change it to 1 and close registry editor.
Restart Internet Explorer and check if the problem has been fixed or not.
Alternate 3:
Right click on My Computer->Properties (or start->Run->sysdm.cpl->ok)
Click on “Advanced” Tab. Click on “Settings” button next to Performance.
Click on last tab “Data Execution Prevention”
Select Second option and then select “Internet Explorer” from the bottom pan.
(If “Internet Explorer” is not already present there then just click on “Add” and then select “c:\Program Files\Internet Explorer\iexplore.exe”)
Click OK and restart internet explorer. The problem should have been fixed.
Thanks,,,I appreciate it,,,it worked for me
We have an Asset Management Program under Oracle that was the only one that was responding with the above error and would not let us log in. I applied the first alternative and now could log in without an issue. But, My concern is, if we disable the memory protection from online attacks, wouldnt that alow internet online attacks and not protect the computer? Would it be better to use alternative 2 then add and select the Asset Management program by turning on the DEP for all except the Asset Management Program? Thanks, this has been very helpful!
After i made the above said changed, the WS_Ftp Pro software started closing down, it is shutting down automatically when trying to connect.
I Love you, very very very thanks. my problem resolved
Hello,
I tried allyour 4 solutions (3 alternatives + jvm.dll) and still it did not fix the issue. Also i dont think the administrator has locked the privelege as I can see the changes after browser restart but i am not sure if there is anything else as its the clients laptop and dont have Administrator password. I am trying to login into Oracle Discoverer. I have XP SP3, IE 8 (8.0.6001), jre1.5.0_10 installed on my laptop.
Please let me know if there is any other alternative to resolve this issue?
Thanks,
MJ
Thanks, it was very useful and worked like a charm !!
Is this really a ‘fix’? So now I’m not protected against buffer overflows just so I can live with some Oracle funkiness??? Can’t Oracle fix something on their end so I don’t have to expose myself to Mr Internet?
Thanks a lot, it solved my problem with SVUonline webdemo and IE 9 on windows 7 64bit.
@Ivan Itchybut
Yes we do understand your concern but the reason being Oracle and Microsoft being independent companies the newer versions of IE are not always compatible with older Oracle forms products. If they release new Jinitiator with new JVM files then you can always update your jinitiator to fix the issue but until that we need to use this fix/workaround.
