Duality Strings Install Issue - taking hours

[mducharme]

Hello,

I'm having a strange problem with Duality Strings. The whole thing installs just fine, except the 2nd Violins B Dark is taking forever to install. It downloaded fast. I cancelled and tried again (after deleting the files in case the download was corrupt) and it does the same thing.

The 2nd violins goes up to 90% pretty quickly, then after that takes about an hour to move 1%. I'm going to leave it running tonight (it is midnight) but I'm not sure it'll be done by tomorrow morning at this rate.

I've never had Vienna Assistant be this slow before with anything. Its kindof ridiculously slow.

It did finally finish - most of it installed in half an hour, but the single file 2nd Violins B Dark took nearly 6 hours to install. I think something is wrong, because I can't understand why that one file would take so many times longer than anything else.

No - what would that have to do with the install taking hours after the entire thing downloaded in 20 minutes? It downloads first, then installs.

Hi, 

Thanks for reporting, this is indeed unusual.

We have tried to reproduce these troubles with different setups and connections - Works as expected. 

I will keep an eye on it! Sorry for the inconvenience!

Best, 
Paul

In case it helps, my system is running Windows 11. In Task Manager, I was monitoring the install. Normally it would write to the SSD at a large number of MB/s, and it did for most of the install. When it reached that file 2nd Violins B Dark, writing to the SSD slowed down to below 0.5MB/s according to Task Manager. I could also see in task manager that even that was not consistent, it would be at 0.5MB/s for one second, then nothing for a second, then 0.5MB/s for a second, then nothing for a second, and the speed would drop even lower as it got further along.

Hmm....... Could very well be a Windows 11 problem. An other reason for me, to stick to Windows 10 for the time being. Just my opinion.

I highly doubt this is a Windows 11-specific bug, even though it is possible. Windows 11 has been out for long enough now that any compatibility issues should be sorted, and I've never had a single compatibility issue - Windows 11 is good for prime time.

I can't see why everything else (including files of similar size) would install just fine, and only the Violins 2 B Dark take a long time. What I might instead suspect is some kind of bug in the underlying Qt framework that the Vienna Assistant is written in. I have a slightly similar issue with the Steinberg Assistant (written in the same framework), where after it finishes downloading a file from Steinberg (say, a component of a Cubase update) and it has gotten the entire file (often getting the entire thing in just a few seconds), it seems to not realize that the download has completed and instead has slowed to very low speeds. When I pause this download and hit the resume button, it instantly realizes that I have the entire file and installs it instead. But, if I don't pause it and hit resume, it will sit there for a very long time (possibly forever) waiting for the file that is already fully downloaded to finish downloading. I think both the Steinberg Assistant and the Vienna Assistant are written using the same Qt framework.

I've also had Qt related bugs in VSL software before, mostly from the software using the wrong copy of the Qt framework on the system. I found that installing certain VSL software in a certain order can cause problems because the newer Qt version installed with certain programs can be overwritten by the older Qt version in other programs. I have to make sure that I install the VSL products in a certain specific order to avoid issues.
