Recommended Patch levels for CUBASE 5 (XP ) and C++?

I have a dedicated music PC ( Windows XP SP2 build) which has no internet connectivity, and hence does not get any regular Microsoft updates.

What is the recommended XP SP level and Microsoft Visual C++ version to be on for Cubase 5?

Can the updates improve performance and minimise CUBASE crashes? I get the usual crash from Microsoft Visual C++ related errors.

I run fully updated XP with no issues. How did you get the elicense software to run without .NET 2.x or higher?

Are all drivers and firmware up to date? Do you have Processor set to Background Services?

I was able to upgrade to 5.5.3 on my interent-free XP SP2 32 bit PC with the following

Installer WindowsXP-KB942288-v3-x86.exe
dotnetfx35.exe (get the full 237MB install, not the online version). This may not be the latest version, but i think that would require XPSP3, which i didn’t want to do at the time.

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
