Repackaging errors during build, please help?

I am trying to package a piece of software and when I attempt to build the project, I receive the following errors:

1) ISDEV : error -1501: Could not compress "C:\Packages\LOCALAPPDATAFOLDER\Microsoft\Windows\WebCache\WebCacheV01.tmp" into "C:\Packages\MSI_Package\Data1.cab"
2) ISDEV : error -6271: File C:\Packages\LOCALAPPDATAFOLDER\Microsoft\Windows\WebCache\WebCacheV01.tmp not found. An error occurred building the MsiFileHash table record for this file. Verify that the file exists in the specified location.
3) ISDEV : error -6103: Could not find file "C:\Packages\LOCALAPPDATAFOLDER\Microsoft\Windows\WebCache\WebCacheV01.tmp"

The build fails and I am unable to move on. Does anyone know what these errors mean, or how to fix? I would really appreciate anyones input on this.

Thank you!
