GroupWise 2014 R2
When performing a Server Install, it is possible that a dialog with the warning "Error writing to file:<filename>" will display. The options are given to "Retry" or "Cancel".
It has been found that if the permissions to the directory are not sufficient, then this error is likely to be displayed.
To correct the problem, examine the file and directory structure referenced in the error and begin examining the permissions for the directory structure beginning at the last directory structure listed and proceeding up the directory tree from there.
For example, if the error displayed showed the error writing the file: C:\Program Files\Novell\GroupWise Server\admin\webapps\gwadmin-console\gwAdminConsole\05F2AE168153243732FBAFCE716D01CE.cache.js, the area to start examining rights would be in the gwAdminConsole directory and then working to the gwadmin-console directory and so on until the directory is found.
To view and modify the permissions, do the following:
Start Windows Explorer
Expand My Computer, and then click the drive that contains the folder that you want to examine
Right-click the folder that you want to examine, and then click Properties
Click the Security tab
Insufficient rights to write the file to the directory structure during the install.
