Hi,
I just tested subtracting a mesh from a dynamesh and ZBrush still crashes as it did in the ZB4R2 release. I have submitted a support ticket and hopefully we can traack this issue down.
Nevertheless, I had hoped for a fix in this release so perhaps I am doing something wrong or need to change some settings or configuration. Any information on this issue would be helpful.
Thanks
XP is not supported for version 4R2b. This was a last-minute item that wasn’t able to make it into the documentation and instructions.
Deactivate 4R2b and delete its folder. Rename your backup folder to “ZBrush 4R2” again. Now run ZBrush and activate it again. This will revert you to 4R2.
If you didn’t back up your folder prior to installing the Update you will need to reinstall 4R2. If you no longer have the installer, submit a Support ticket and be sure to specify that you’re using XP.
That’s disapointing; I was just getting into playing with FiberMesh and grooming brushes which are absolutly fantastic! Are we at a point where Windows 7 is essential to have the full benefit of new functionality?
I assume ZB5 being 64 bit will require it; I just want to know if now is the time to consider migrating over to Win 7.
My system will support it but my wallet, not to mention my wife, aren’t all that thrilled given the current economic climate.
Ouch! I feel your pain. You can pick up an OEM of Windows 7 Home Premium 64bit for about $100.00.
OEM (legitimate OEM as opposed to pirated OEM) can only be sold with the purchase of a motherboard and CPU.
However, there are upgrade versions of Windows available for less than the regular price. Home Premium on Amazon is currently $110 (http://www.amazon.com/Microsoft-Windows-Home-Premium-Upgrade/dp/B002DHLUWK/ref=sr_1_2?ie=UTF8&qid=1327427151&sr=8-2) and will upgrade XP or Vista.
This is unfortunately a reality with the software industry. Sooner or later, new features outstrip older OS’s ability to support those features. With most programs it never really becomes seen as an issue because most programs don’t keep giving out free upgrades. By the time the program has outlived the OS, you’ve usually moved on to another app and never even realize it happened. 
We have tried very hard to maintain support for older operating systems for as long as we could. Eventually, though, it’s just not possible anymore.
On the other hand… it’s a great way to justify the new OS to your missus. “Hey honey… think how much money I haven’t had to spend on ZBrush upgrades!” 
Oh, OK, I didn’t know that. Thanks. Mine is OEM, but I did build my own PC and bought it at that time. I didn’t realize you can only get it with new MoBo and CPU purchase.
I was still having this problem as well after installing the update. I was hoping this would be addressed with this release, but I wasn’t aware that Pixologic had finally dropped support for XP systems. Now I know!
I will say that I finally tried the 3gb switch and it did allow me to use negative meshes. I’m not sure it’s the ideal solution, but I’m pretty sure it’s the cheapest one. I would encourage anyone still having this problem to at least give the 3gb switch a try. So far I am running Zbrush 4r2b on a 32bit XP with only minor issues.
Aurick, I agree; without buying a new system I would not seek an OEM solution. When I purchased my BOXX system 5+ years ago I made sure it would support a 64bit OS. I knew that eventually I would need to make the change sooner or later and it looks as though that time has come.
I do appreciate everything you and the entire team at Pixologic has done in the realm of digital art. Pixologic’s innovation is amazing and your generosity is a breath of fresh air in an increasingly cynical world.
The price of an OS upgrade is virtually insignificant compared to what I have saved due to Pixologic’s generosity. I’ll see if my wife will buy into that proposition.
However I will not be surprised if, like Cuba Gooding Jr in the movie “Jerry Maguire”, she taunts me into screaming “Show me the money!” as my freelance digital art career crawls ragged and thirsty through the desert that is our current economy.
So as I wax poetic drifting back to that world of imagination and swirling pixols, where the faint of heart dare not go, I thank you my friend and the entire Pixologic team for the epic journey that is ZBrush.
Happy ZBrushing
