TL;DR: Read the title of this thread. No question.
Update: All conclusions from this thread works with Dorico Pro 3. However, on modern computers, Dorico Pro 3 can utilize your GPU more efficiently under Windows 10 (according to my personal tests, which may be different than how Dorico Pro 3 behaves on your computers).
Update: Based on my compatibility tests, if you are using Windows 7, then the Windows Aero (a.k.a. DWM Service) must be enabled and hardware-accelerated (even if you are running Windows 7 Home Basic, regardless the availability of transparent glass visual effect) because Dorico 2 Audio Engine NEEDS THAT. // Later, Daniel told me that the requirements of Windows Aero also exists for Dorico 1.
Most Windows 7 users prefer its ability of completely turning the Windows Aero off which benefits some old computers that uses Intel(R) integrated graphics, reducing the CPU workload. This is one of common reasons explaining why they refuse to use Windows 8 and later. However, if Windows Aero is turned off, then the installation of Platform Update won’t make any sense to Dorico, hence why all dump files look identical to each other (from Ulf’s perspective).
If you are using Windows 7 Embedded x64, then please make sure Windows Aero is installed (I guess it is not removable if adding the packages and dependencies of Windows Explorer Shell support).
(This also proves that Dorico 2 is NOT COMPATIBLE with “WINDOWS 7 STARTER” which has no Windows Aero support and no x64 edition available; Windows Thin PC (a special version of Windows 7 Embedded x86) only has 32bit edition, hence being unable to run Dorico 2.)
Also, according to Ulf, Windows NT 6.1 Platform Update provides crucial support for Dorico 2 running on Windows 7 SP1 x64:
P.S.: At least .netfx 4.x is required for eLicense control center at this moment.
Also, higher .netfx version requirements may come to the incoming next generation eLicense control center + driver suite in the future.
------Previous Post------
I tested Dorico 2 on Windows 7 Home Basic SP1 (with .netfx 4.7.2 installed) through both VMware Fusion and Parallels Desktop.
The Dorico 2 itself passed the eLc check (using USB dongle connected to the virtural machine) and successfully booted up.
However, it immediately shows that the audio engine process “died” and then the Dorico application freezes permanently.
I have no approaches at this moment to test Dorico 2 Compatibility with Windows 7 on an actural machine, hence this thread for attraction and feedback.
P.S.: This test is a voluntary work simply because the forced Windows Update of Windows 10 attracted huge amount of hatred… and some of these haters are also discriminating Apple-related products, hence their choice of Windows 7 or 8.x builds.
