Resolved: Internal Error, unable to open/save ZProject.dll

PARENT-SUPPORT CHILD-Startup And Compatibility Troubleshooting
#1

I have just installed ZBrush 4 and have immediately run into this problem. Upon starting up ZBrush, it shows an internal error window with the text:

INTERNAL ERROR.\AFile.cpp Line:728
Unable to open/Create a FileC:\PROGRAM FILES (X86)\PIXOLOGIC\ZBRUSH 4.0/ZData\ZPlugs/ZProject.dll

It then invites me to either click OK to exit ZBrush or Cancel to continue. If I hit Cancel, it shows a window with this text:

Unable To Save File
C:\PROGRAM FILES (X86)\PIXOLOGIC\ZBRUSH 4.0/ZData\ZPlugs/ZProject.dll

In a possibly related problem, ZBrush is not remembering that it’s been registered. After hitting OK on the last error message, it brings up the registration window. I went through the paces of registering the program, and it actually said “Registration Successful” or something to that effect. From there, I can use the program normally.

However, when I close ZBrush, these problems return. The two error messages, AND the registration window. It apparently does not save any information regarding my registration, but using the same registration code does not work, saying that the registration failed. I have to actually reapply for a registration code in order to use the program again.

I’ve been using ZBrush for a couple years, and have never come across a problem like this. I recently upgraded from Windows Vista to Windows 7 Ultimate x64. Could that possibly be to blame?

Any help would be GREATLY appreciated!

Something is messed up with the permissions. ZBrush is unable to write to its own folder and subfolders.

ZBrush should be installed and activated by an administrator account. Under most network environments it then runs for all accounts on that computer. It cannot be successfully installed and activated by a regular user account.

If it was installed and activated by an admin, then there is something unusual about how your computer’s permissions are set up. All I can tell you in this situation is that ZBrush must be able to write to its own folder and subfolders. Once you’ve fixed the permissions to allow that, these problems will go away.

Thanks very much! That fixed the problem nicely. I feel kind of silly for not having thought of that myself.:o
