Your response mashedmitten with item numbers added :-
“I run fully updated XP with no issues.
1- How did you get the elicense software to run without .NET 2.x or higher?
2- Are all drivers and firmware up to date?
3- Do you have Processor set to Background Services?”
My Windows XP system was built by a professional, and ensured , Cubase 4 at the time, was up and running.
All disks fully partitioned, firewire interface working for the interface unit I a provided to him.
I did not have to get involved in the technical set up. It was tuned at the OS level by this specialist.
But after 4 years of no updates on the XP side ( ie, still on SP2) but now on Cubase 5.5, I thought it appropriate to ask the question. Cubase software has moved on a lot , but not my dedicated XP music PC system.
As mentioned, I get occasional Cubase 5.5 crashes relating to Microsoft Visual C++ errors, when I try to add an effect plug in to a track.
Your items :-
1 - I assume you are implying that I need access to the internet for .NET 2.x - I use my home computer for downloading Cubase updates etc.
2- The only drivers I would require updating are the firewire drivers for my one and only audio interface and USB keyboard. I can download these updates as necessary from the manufactures website, which I have done at least once. The firmware has not been updated, to my knowledge, but that is a question to Steinberg - is it necessary, and if so what is the optimum build/version level for XP at SP2 or at SP3 , so as to work better with Cubase 5.5 - your takeaway
3- I have not tweaked any of the background services - I know there are websites which recommend removal of non essential services, which I will look into. This may improve performance, but it would certainly not stop the Cubase crashes IMHO
