RPK200189: Unable to build RPP project containing UNC paths in RPSourcePath table

Product:        RayPack

Version/-s:     4.0

Issue:          Unable to build RPP project containing UNC paths in RPSourcePath table

Jira-Task:      RPK-2145


The problem occurs if file paths saved in RPSourcePath table are using UNC format (for example \\server\share\file1.txt) or if the path is resolved to a value being in UNC format.

In affected product versions, building such projects may result in a message saying that there are missing files. This effectively means that the project cannot be built.

Versions prior to 4.0 are not affected by this issue.

Workaround:     Yes



Move files to a local drive and build the project from local sources, or map the UNC share using a drive letter (for example W:\Share) with help of 'net use' command (see https://technet.microsoft.com/en-us/library/bb490717.aspx?f=255&MSPPError=-2147217396). Make sure the paths in RPSourcePath table are not hardcoded - otherwise, use the Table View to adjust them to a local or mounted path.

Patch 1 and/or hotfix (see below) makes this workaround obsolete, as they can correctly check linked source paths.


  1. Close all instanced of RayPack.
  2. Download the attached .dll file and extract it to the /Libraries subfolder where RayPack is installed (by default C:\Program Files (x86)\RayPack\Libraries for a single installation and C:\Program Files (x86)\PackagingSuite\RayPack for Packaging Suite installation).
  3. Overwrite the previous version of the file (you may want to back it up first).
  4. (Only for Windows 8, 8.1 and 10 users) Make sure the new file is not blocked by Windows by going to its properties and pressing the Unblock file button (Windows 8/8.1) or unchecking the checkbox (Windows 10).
  5. Start RayPack, open the project and rebuild it.

Resolved in:    4.0 Patch 1
