I've had this problem before, and never got any help. I am not able to install any Wolfram products. I download the download manager .exe OK. But when I run it (by double clicking on it), it hangs. I see it on the task manger. Eventually it times out.
According to instructions, it is supposed to open "immediately". Yet., this has never happened to me. This window never opens. So I have no idea why it says "immediately"
I made sure also the desktop is clear, just in case it is hiding behind some window.
I had this problem before when I tried to install the Wolfram player. Same thing happens. I download the DM.exe OK. But it never runs. Here is a link Today, I wanted to install 11.3 on windows 7. I downloaded Mathematica_11.3.0_WIN_DM.exe
OK. But again, it does not start.
I also tried running it as administrator. No help. it still hangs.
I do not use Windows firewall. I use ESET security/anti-virus software. Been using it for many years with no problems from any software. But I also disabled this software now to see if it has any effect, then tried running the Mathematica download manager. It still hanged.
I also booted the PC in safe mode (but with network enabled). Then Tried running DM manager. Again, it hangs. Even in safe mode.
If I leave it running, after about 40 minutes of so, it times out.
If I try to run it a second time while waiting for the first one, which is still running, I get error that only one instance is allowed to run
This whole process of installing Mathematica is broke. Before, I would just download the .exe itself. I do not care if it was 10 GB. Now, I can't install any Wolfram product using this download manager thing.
Is it possible to download the actual installer.exe or the product file itself without having to download this small download manager (as used to be the case before?) It does not matter if it too large. I see that on Linux, there is no download manager. But only for windows and Mac. It will be better to also give the choice to customer to either use the download manager or to download the file directly itself, and let customers decide what to do.
I have no idea why it does not start. I can't see any errors. I see it sitting there in the task manager and nothing happens.
My PC is home edition, running windows 7, 64 bit. Latest version. Any ideas what to do?
