Floating licenses use a server rather than a serial number.  If you have a serial number, you do not have a floating license and this article does not apply to you.

At this time, we are working on fixing issues that were found in 4R7 after it was "in the wild" and being used by thousands of people.  Some of these issues are significant and releasing the patch to fix them has proven to be taking longer than expected.  We recognize that floating license customers typically use ZBrush in enterprise environments where they depend upon the software being as stable as possible.  Further, it is not feasible in a team environment for some users to stay with 4R6 while others are using 4R7 -- that would result in file compatibility issues that can bring production to a standstill.

For these reasons, we will not be releasing 4R7 for floating licenses until we have been able to release the patch fixing these issues.

Our current estimate is that this patch will be released during the first half of March, immediately followed by the floating license client.

If you have floating licenses, we recommend that you subscribe to the RSS feed on the main Support page.  As soon as the floating client is released we will be updating it with a news article to let everyone know.  Subscribing to the RSS feed will ensure that you are notified immediately when that happens.

Thank you!

ZBrush 4R7 is now available as a FREE upgrade for all registered users.

You may upgrade immediately at the Pixologic Website:  CLICK HERE

Please note that the Auto Update feature cannot be used for this upgrade.  You will need to use the stand-alone installer from the link above.  You will also need your serial number, which is the same one that you have had for every release in the ZBrush 4.x series.

For information about ZBrush 4R7 and its features, visit the Pixologic Website's feature pages.

An FAQ covering common issues with upgrading can be found here:  ZBC FAQ Thread

ZBrush 4R7 supports -- but does not include -- the ZBrush to KeyShot Bridge and any release of KeyShot 5.  The ZBrush to KeyShot Bridge may be purchased from the Pixologic Store.  There you will also find a special edition KeyShot for ZBrush.

Special note for Floating Licenses:  The patch to fix issues with 4R7 has proven to be more complicated than expected.  As a result, the floating client for ZBrush 4R7 has been delayed by up to two weeks.  The new estimate is before the middle of March.  If you have a server-based/networked license instead of a serial number you will need to wait for the floating client to be released.  We recommend subscribing to the Support RSS feed so that you can be notified as soon as it is available.  We apologize for the delay.

Update 7/18/2014:  Avast's most recent updates appear to have resolved this issue.  If you have Avast and your ZBrush.exe was removed, please follow the instructions below.  If you have Avast and have not been affected, you should no longer need to worry about it after making sure you are updated to the most current Avast update.  Thanks!

As of this morning, Avast Antivirus has started spontaneously deleting the ZBrush.exe from computers.  We are currently communicating with the publisher to have the issue resolved.  There is no ETA on this, however.

If your copy of ZBrush has been deleted, here are methods to get it back:

1. Open Avast, right-click on one of the four big icons (the "Add one if it's available) and choose Change Shortcut > Virus Chest.  Now click on the Virus Chest shortcut.  Within the Virus Chest you will hopefully see the ZBrush.exe.  If so, right-click it and choose "Restore and Add to exclusions".  This will put ZBrush back and also prevent Avast from repeating its mistake.
2. If ZBrush is not found in the Virus Chest then you will need to reinstall it.  There are two ways to do this:
   • Reinstall ZBrush over top of your original installation.  (Recommended)
   • Install ZBrush to a temporary location, copy the ZBrush.exe back into its proper location and then uninstall the new installation.  

• Note: Neither of these methods will add ZBrush to Avast's exclusions list, so you should make a backup copy of the ZBrush.exe just in case Avast removes it again.  If you don't have a backup copy of your ZBrush installer you will need to download it again.  If you originally purchased ZBrush at version 4R5 or earlier, you can get the installer from https://pixologic.com/zbrush/downloadcenter/instructions/full-installer.php.  If you purchased ZBrush 4R6 then the download link will be in the same email that has your serial number.  Please be aware that download links are valid for 2 downloads or 1 week, whichever comes first.  As a result, you may get a message telling you that your download has expired.  In that case you will need to submit a Support ticket so that we can renew your download for you.

Unfortunately, this is something that was totally beyond our control and impossible for us to predict.  However, we hope that the above information will help you out.  If you do need further assistance, please submit a Support ticket.  We will be happy to help!

Happy ZBrushing!
