Hello! I am using Internet Explorer 8 on a Dell desktop computer running Windows 7 Professional 32-bit. This computer is in a pharmacy and therefore has high security protection (firewalls, I'm assuming?). A music program wasn't working properly, and troubleshooting suggested I update my flash player.
I try to download the new version's Flash Player installer for IE on Windows, and it downloads fine for a second (up to, say, 10-20% downloaded). Then progress halts and my download speed goes down to 12 bytes/sec. [Sidebar - downloads unrelated to flash player, sending/receiving info in other programs, and streaming music are all working fine.] If I pause the download and resume, it completes in less than a second, but then I run into problems installing. It will install to 47% and then I get an error message saying "Cannot contact reliable source". Another message I have run into is "Certificate authentication failed, please re-install to correct the problem."
On the website for troubleshooting Flash Player downloading & installing, it suggested uninstalling the current version of flash player before installing the new version. I have done so, but it didn't resolve the problem, and now I am totally hooped with no functional flash player on my computer.
It sounds like you might be running into a firewall/proxy issue. Can you try installing our stand alone installer located on this page?
