still have a few rendernodes running xp64.

the latest beta gives me a "maxwell.exe is not a valid 32bit application" error when it is started. (3.0 was running fine)
could I be missing some updates, runtime binaries? win update is not running on the nodes.

or is XP no longer supported for node rendering?

[dk2079]

system requirements still list XP:

The minimum system requirements for Maxwell Render V3 are as follows:
Windows (32 and 64)

Windows XP, Windows Vista, Windows Server 2008, Windows 7, Windows 8, Windows 10
2 GHz Intel® Core2 processor, AMD Athlon 64 or better
1GB RAM minimum. 4 GB of RAM memory is highly recommended
400 MB available hard disk space for installation
Accelerated OpenGL drivers
3 button mouse recommended

is this info out of date?

[JDHill]

To be precise, the answer is both yes and no: that information will be out of date when 3.2 is released, because XP will no longer be supported.

In my opinion, though, it should already have been changed, because "supported" can be interpreted to mean that a) "it is possible to run the program on XP" and/or b) "we officially support running the program on XP", where regardless whether (a) may be true, (b) can only be false, because from a development perspective, XP no longer exists, having been officially retired by Microsoft. I will talk with some people and see about updating the system requirements to reflect this.

Thanks for the clarification Jeremy.
true 3.1.99.10 is not 3.0 but noting it somewhere on the Beta Download page is probably a good thing.


the situation is, we still have quite a few old machines running Q6600s/8GB. they are of course not the star of the show but get stuff done too.

Now there are two options:

1- upgrade to win7 x64 (put money in old machines..)
2- change to linux

I however have read here that such old CPUs might have troubles rendering on Linux.
Now before I get into reinstalling and so on, I was hoping to get some info on if this will actually work?

[JDHill]

I don't personally know, and would doubt NL has an actual 6600 with which to test. That is an old CPU (released in 2007), but it supports SSE/SSE2/SSE3, which I think should be sufficient for Maxwell, though I can't say for a particular flavor/version of linux. I'm not sure what "illegal instruction" was being referenced in the thread you linked, but that was from nearly a year ago, and if you are determined to use these machines without upgrading Windows, I would probably just take one of them, put in an empty drive, and then install centos (maybe a good choice, since it tries to be stable, not cutting-edge, and since the Maxwell sys reqs page says that Maxwell is tested on centos 6.5 -- I have run this myself, but only on haswell) or whatever on it, to confirm whether it works. That would be the quickest (and the only 100% sure) way, to know.

I was running Maxwell fine on Ubuntu. Only sometimes there were startup stability problems - Maxwell started and then exited right away, but didn't have time to solve it.

hey Jeremy,
thanks for the tip.

installed centos 7 but I am stuck with the environment variable.

the linux beta is a tarball and does not create the variables automatically.

If you have a quick tip how to do this I would be very thankful. (played with arch linux some years ago.. don't remember much :/ )

I tried what Miguel suggested in the thread http://www.maxwellrender.com/forum/view ... 16&t=38523

I of course corrected the path to 3.1 etc, but no success.

the thing is I kinda registered the variables but can't get maxwell to start.

here goes a real "screenshot".. trying to copy the png from linux back to win sever gives ma an "invalid argument" ...zzzz



also I am not sure if it should be:

1 done via Terminal ( execute the line "export MAXWELL3_ROOT=......)

2 put into .bash_profile

3 put into .bashrc ( using this guide)

4 and in which user profile? root I only use to copy extracted maxwell directory into /opt, right? so I should do this in §Home of the user I want to render with?

[JDHill]

Say that you unarchived the download to ~/Maxwell. You can then open a terminal and:

Code: Select all

gedit .bash_profile

At the bottom of the file, add:

Code: Select all

export MAXWELL3_ROOT=~/Maxwell

Back in the shell, refresh the environment and run Maxwell:

Code: Select all

source .bash_profile
./Maxwell/maxwell

Maxwell should start up. To start it by double-clicking in a file browser, you will need to log out, then log back in. This would be for a user-local install; if you instead installed it to /opt/Maxwell, then you could add export MAXWELL3_ROOT=/opt/Maxwell to /etc/environment, log out and back in, and it should work for any user.

gotcha, /etc/environment did it
