I was wondering if anybody could help figure out what is wrong.
I've downloaded Quartus (91_quartus_free.exe) twice, and Model Sim (91_modelsim_ase_windows.exe) once and they don't seem to work.
When I double click the installer, I get the standard "Do you want to allow the following program from an unknown publisher to make change to your computer?" prompt, to which I say Yes.
After that, nothing happens. The prompt goes away, I check Task Manager and there is no new process. I've also tried running as Administrator and in XPSP2 compatibility mode.
My box is a Windows 7 Ultimate, (64bit) fresh out of the install (I just installed Windows & nothing else about 3 days ago). I've checked that Windows Installer service is running, and I've not disabled any services.
Can anybody help work out what's wrong? Is there a log / debug mode for the installer?
