Qt SDK Installation Download Error
I am trying to install the Qt SDK. I have downloaded the LGPL Qt SDK for Windows. I run the installer, select the default installation, and click Install. The installation runs for about one minute, gets to the Symbian Development files, and stops. There is no network utilization for a few minutes, and then the connection times out and an error is displayed. Here is a screenshot:
I have run the installer at least 10 times, and it never works. I am running Windows 7, and I have plenty of free space on my hard disk and RAM.
This has had me stumped for hours. Any help will be appreciated.
I agree, I think it is a connection problem. I have tried with a wireless connection and a cable connection. I have also re-started my computer. Nothing works.
By the way, it doesn’t always stop on “Symbian Development Files”. Sometimes it stops at “MinGW 4.4” or another place, but it never gets past about 5%.
I downloaded the offline installer, and double-clicked on it to run it. The normal warning “The publisher could not be verified. Are you sure you want to run this software?” pops up, and I click “Run”. But nothing happens. The task manager shows that no Qt processes are running.
I am beginning to think that this is a problem with my computer, or maybe with my firewall. I will try disabling my firewall temporarily.
Firewall should have no interference with the offline installer, maybe the firewall caused the online installer failures, but for the offline version only the antivirus has work to do (so you can try to temporary disable the virus shield).
Are you sure that there is no process running? Because this couple of minutes waiting period after the double-click is normal behavior – the installer is compressed and it has to decompress some files before it can start.
Yeah, I completely turned off my anti-virus (Microsoft Security Essentials), which includes the firewall and the virus shield. I tried running both the online and offline installers, but there is no difference.
Yes, I had to wait for about 1 minute while my computer was busy. Actually, I tried again, and the process pops onto the task manager for about 1 second, and then goes off.
In response to your earlier post, yes, I have tried to run both installers with “Run as Administrator”, but to no avail.
I am sure that this is a problem with my computer. The question is how to fix it.
Well, my computer is running on a network in a workplace, and the network administrator had installed a program called NetNanny that monitors our internet activity. For some reason, it was blocking the online installer from downloading the necessary files. I contacted the network administrator, and asked him to make an exception for the installers. After he made the exception, out of curiosity, I tried the offline installer, but it still didn’t run. Then I tried the online installer, and it ran fine.
I still don’t know what the problem was with the offline installer. Perhaps 1.5 Gb was too much for my system to handle. Anyways, the problem is solved.
Thanks again for your help.
