Re: Windows has blocked this software because it can't verify the

Thanks Jan; I've tried all of that. After reading the popup message again I
noticed it said that 'Windows' has blocked the software! I think I should be
looking for a Windows setting rather than IE setting. The software that is
being blocked is a .cab file. I wonder what Windows setting might check for
invalid certificates?

Can anyone think of what Windows setting might be blocking the software?

Try the following and see if it helps:

First: It is very important that the time of your computer clock is correct.
Every Certificate has an expiration and start date. When your machine clock
time or date is off, even just a few minutes or hours, it may cause the
Certificates to be seen as invalid or expired, which can cause various
problems. So, be sure your machine date and time are always set correctly.

If still no joy....

Go to IE>Tools>Internet Options>Advanced
Scroll down to the Security Section
Check "Allow software to run or install even if the signature is invalid"

UNCheck the following
"Check for publisher's certificate revocation"
"Warn about invalid site certificates"

If that does not work, you might also try:

Go to Tools>Internet Options>Security tab>highlight Internet
Click Custom level tab>scroll down and Uncheck "Don't prompt for
client certificate selection when no certificates or only one certificate


How can I turn off the "security alert" dialog boxes that appears when I
open a webpage

How to make a good newsgroup post:

After loggin to my a secure website to view my store cameras I receive the
following message:

Windows has blocked this software because it can't verify the publisher.
Publisher: Unknown Publisher.

I am using xp-pro sp2 also xp-home sp2 with IE6. Everything works well on
Windows 98se with IE6.

When I navigate to the page I allow the ActiveX blocker to download the
and I see the camera program. Then I get the message that the .cab has
blocked. I have entered the site as a trusted site and reset my security
settings to the lowest settings but still am not able to download the
There is NO option to save the file to disk.

ie. the camera program loads ok but it needs to download the .cab as a
viewer. This is a Samsung camera console unit that has a webserver and
server built in. The security certificate is out of date but this is a
legitimate program and I need to use it even if it is out of date. I have
saved the certificate to my trusted certificates but that doesn't help.

Does anyone have any suggestions about how I can workaround this problem??
There must be SOME way to allow this program!!
