If there are two files in the same source folder of a package. For example, one file is called logger.man, the other file is called logger~1. The machine is using short file name and the package has "compress file for distribution" option selected.
Double click on the .osd file for the package under staging/command folder will result in the error below in the installation log:
Download OK for "xxxxx/logger.man.gz"
Downloaded file size is incorrect, should be xxxxx
Once compressed, the short file name for "logger.man.gz" is "logger~1.gz" which is the same file name once logger~1 is compressed (logger~1.gz). It end up the contents of logger.man.gz is overwritten by the contents of logger~1.gz. And the logger~1.gz will not appear in the folder after compression.
- Change one of the file name so the short file names for both files will not be the same. If these are part of the msisource for a msi package, the msi file has to be changed to reflect the file name change.
- Distributing without compression does not resolve the problem in this case - files are still clashing
